    Regulating a Polluting Firm Under Asymmetric Information (1997)

    Notes: Abstract This paper reinterprets the Laffont-Tirole model of regulation under asymmetric information to cover the case of pollution control. The asymmetry of information concerns the firm's cost of lowering its pollution. The regulator has three objectives: Ensuring an efficient abatement level, generating 'green taxes' and securing the survival of the firm. We show that when optimal abatement is important relative to tax generation, the regulator cannot use the policy of offering the firm a set of linear tax schemes from which to choose. By contrast, this policy is optimal in the Laffont-Tirole model under certain not very restrictive assumptions. We proceed to establish a simple rule for when to shut-down inefficient types. In an example with specific functional forms, we derive the optimal tax function both analytically and graphically. We show the effect on the optimal tax system of a change in a technological parameter.

    Notes: Abstract The Tagus estuary, located at the western Iberian coast in front of Lisbon is the largest one in Portugal, where it drains highly populated and industrialised regions. The amount of sediment transported by this river is so great that the submarine delta is one of the largest in the Iberian margin, very well defined and reaching the 70m isobath. The geochemical pattern of the muddy deposit off the Tagus river has been determined by elemental analyses of bulk surficial sediments, collected at the Portuguese margin adjacent to the Tagus estuary. Measurements were carried out by energy-dispersive X-ray fluorescence spectrometry (EDXRF). Sediments were usually composed of fine particles (silts and clays) and were high in organic matter (measured as loss on ignition). Elemental concentrations for Zn and Pb clearly indicate an estuarine contamination probably associated with discharges from urban centers or due to the influence of the industries located downstream. Apparently the depletion on the Cu contents is caused by its release (soluble complexes) into the marine environment. Variations observed in the elemental distribution of the sediments off the Tagus with distance from the estuary seem to be dependent on the grain size distribution related to the dynamics of the sediment transport.

    Notes: Abstract A combined statistical and computergraphic approach is proposed for apportionment and attribution of soil contaminants in complex areas. The field test site lies north of Swansea, south Wales and contains two major pollutant sources, an active nickel refiner and (4 km away) the site of major base metal smelting in the nineteenth century (the Lower Swansea Valley reclamation study area). Soil samples (70 samples, 0–15 cm) were collected on a regular grid of 1000 m interval. They were extracted using 0.05 M diammonium EDTA and the extracts analysed for Cd, Co, Cu, Fe, Mn, Ni, Pb and Zn. Soil pH and %organic content were also determined. Factor analysis yielded three groups which explained 73.8% of the data variance (1: Cd, Cu, %OM, Pb, Zn, Ni; 2: Cd, Zn, Mn, pH; 3: Cu, Mn, Co, Ni, Fe). Isoline plots were classifiable into the same three groups. It was concluded that factor 3 contained those elements associated with smelter emissions, factor 1 with contamination from the Lower Swansea Valley and in factor 2 pedogenetic processes control the occurrence of the elements.

    Notes: Abstract A study was carried out recently to determine the pollution level of waters in the Karachi harbour and adjoining backwaters. Nine locations were selected, four in the backwaters, two on the seaside, and three in the main navigable channel. Four of these locations were deliberately selected to coincide with those of a previous study conducted in 1982 by Pakistan Council of Scientific and Industrial Research (PCSIR) so that the values for the concentration of different pollutants could be compared. Analysis was conducted for pH, bicarbonates, Total Solids, Volatile matter in Total Solids, Chlorides, Sulphates, Calcium, Magnesium, Sodium and Potassium. The results indicate that the composition of sea water as far as the concentration of above constituents is concerned has not changed much since the time of the PCSIR study, viz 1982, except that the organic matter concentration has increased. The reasons for this increase in organic loading and its possible impact are discussed in this paper.

    Notes: Abstract The space-time distribution of some pollutants (Cu, Ph, Zn, Cd, Fe, Mn, V, Ni, Cr) in the sludge of the canals of Venice was studied. The contamination levels were comparable to, or higher, than those measured in the most polluted sediments of the Lagoon of Venice Sediments were collected by two different sampling techniques I ) collection of sediment cores (upper 5 cm) by a syringe-type corer, 2) collection by traps, placed on the bottom of the canal Traps pennitted the sampling of sediments essentially resuspended by overlying water turbulence This sediment fraction is subjected to variations of its physicochemical parameters (principally change of redox conditions) and therefore to pollutant exchange at the water/sediment interface The metals principally exchanged during sediment resuspension were Cd, Pb, Zn and Cu These metals have principally an anthropogenic origin and are bound to the most labile geochemical phases of the sediment (such as sulphides), which can be oxidised during sediment resuspension, releasing metals into the water Fe, Cr and Ni were only partially exchanged, while Mn and V were generally not exchanged, a significant fraction of these metals is of natural origin and is bound to the most refractory phases of the sediment.

    Notes: Abstract A fugacity-based model to explain the partitioning of contaminants in the environment is evaluated. Using emission inventories, air and water concentrations predicted by the model for the southwestern Québec region generally agree with field data for phenanthrene,α-HCH, lindane, and DDT. For pyrene, air concentrations are in agreement but water concentrations were in error by a factor of nearly 20. There is also a possibility for using the model to predict emissions from known air and water concentrations. The model was run over 120 times each for phenanthrene, HCB, and lindane while randomly varying the input parameters each time. A Principal Components Analysis and a partial correlation analysis indicate that certain input parameters are more important for some compounds than for others and that log K ow is the physical-chemical property of greatest importance.

    Notes: Abstract In many forested wetlands of Louisiana, surface water quality is being deteriorated by nutrient input from adjacent agricultural production area. This field study assesses the input of fertilizer N, applied to sugarcane fields, to forested wetlands. The potential use of natural abundance variations in15N/14N ratios for identification and tracing surface water N sources (NH 4 + - and NO 3 − -N) was evaluated. Runoff and surface water samples were collected from sugarcane fields and bordering forested wetlands (6 stations) over a 16 month period and analyzed for NH 4 + -N, NO 3 − -N, and associated NH 4 + -δ 15N and NO 3 − -δ 15N ratios. FertilizerN draining into adjacent forested wetland was estimated to be only a small fraction of the amount applied. Concentrations of NH 4 + - and NO 3 − -N in the collected water samples were low and ranged from 0.02 to 1.79 mg L−1. Isotopic analysis revealed NH 4 + -δ 15N and NO 3 − -δ 15N means were distinctive and may have the potential to be used as tracers of N contamination. The mean NH 4 + -δ 15N value was +18.6±7.1‰ and the NO 3 − -δ 15N mean was +8.3±3.1‰. Anomalously high NO 3 − -δ 15N values (〉30‰) were attributed to denitrification.

    Notes: Abstract Concentrations of HCB, DDTs and PCBs in the tissues andorgans of cetaceans ( Stenella coeruleoalba, Tursiops truncatus, Balaenoptera physalus, Steno bredanensis}, Grampus griseus} and Globicephala melaena) strandedalong the Italian coasts in the period 1987–1993 are reported. The values are compared between speciesand between specimens of the samespecies. Chlorinated hydrocarbon (CH) levels were found toincrease in relation to the quantity andtype of lipids in each tissue and organ. Differences inaccumulation encountered in the differentspecies are principally due to different feeding habitats.Remarkable differences found between malesand females of each species confirm that during gestation andlactation, females undergo disintoxication by passing much of their total burden of CHs to their young.

    Notes: Abstract Since the early 1990's, large areas of mangrove forest along the nearshore waters of Cukai bay had been cleared to give way for the development of aquaculture activities, human settlement and setting up of new small scale fish processing industries. The Cukai bay, facing the South China Sea, has inflows from the Cukai river estuaries and other numerous small river tributaries. The water quality examined (April 1993 to March 1994) in the bay indicated that the ammonium, nitrate and phosphorus contents were high during the pre-wet monsoon (October 1993) with values of 28.2, 30.1 and 29.6 μg L-1, respectively. The source of nutrients in the estuary were from the newly established fish processing cottage industries, nearby fish culture activities, agro-based effluents (mainly fertilisers from surrounding paddy plantations), untreated human (from nearby villages) and animal wastes (from domestic cattle and goat farms) and siltation due to erosion from land development. The main bulk of the microplankton were comprised of diatoms, dinoflagellates, ciliophora and blue green algae. The blue green algae encountered were species of Lyngbya, Oscillatoria, Phormodium and Trichodesmium while those of diatom were species of Asterionella, Chaetoceros, Coscinodiscus, Navicula and Nitzschia. Peak microplankton production in the water column occurred in October 1993, reaching a maximum value of 173 μg C L-1 d-1. This comprised primarily of the blue green alga, Trichodesmium thiebautii.

    Notes: Abstract The probability that the concentrations of toxic substances in soil or other medium exceed tolerablemaxima at any unsampled place can be estimated by indicator geostatistics. The method is developed and used to estimate and map the risk of contamination by cadmium, copper and lead in the topsoil of a 14.5 km 2 region in the Swiss Jura. It combines both direct measurements of metal concentrations and thecalibration of a geological map, and it shows that the risk of toxicity is least on Argovian rocks. Two approaches are proposed to divide a region into safe' and 'hazardous' zones on the basis of probability maps. The first declares as contaminated all places where the risk of contamination exceeds a given threshold. The second approach first evaluates the financial costs that might result from a wrongdeclaration, after which the site is allocated to a class so as to minimize that cost. The risk of exposure for humans and animals is generally greater for contaminated agricultural land than for forest soil, and so land use is taken into account in both procedures.

    Notes: Abstract The paper begins with a brief analysis of the concepts of environmental justice and environmental racism and classism. The authors argue that pollution- and environment-related decision-making is prima facie wrong whenever it results in inequitable treatment of individuals on the basis of race or socio-economic status. The essay next surveys the history of the doctrine of free informed consent and argues that the consent of those affected is necessary for ensuring the fairness of decision-making for siting hazardous facilities. The paper also points out that equal opportunity to environmental protection and free informed consent are important rights. Finally, it presents a case study on the proposed uranium enrichment facility near Homer, Louisiana and argues that siting the plant would violate norms of distributive equity and free informed consent. It concludes that siting the facility is a case of environmental injustice and likely an example of environmental racism or classism.

    Optimal pollution taxation in a Cournot duopoly (1995)

    Notes: Abstract It is well known that the optimal pollution tax in a competitive industry is equal to the marginal damage inflicted by the pollution. It has also been shown that the optimal pollution tax on a monopoly is less than the marginal damage. In this paper, I derive the optimal pollution tax for a Cournot duopoly. If firms have different production costs, the optimal tax rate may exceed the marginal damage. This is so because the tax may be an effective instrument for allocating production from the less to the more efficient firm. It is also shown that, if one firm has a positive most preferred pollution tax, the sum of consumer and producer surpluses will be declining in the tax at this level.

    Notes: Abstract This article concerns itself with the environmental role of heavily polluting industries since 1970, analysing its development in 11 basic industries, as well as electricity production and road transport, in 32 industrial countries. It argues for a green industrial policy, demonstrating that other mitigations of environmental pressure in industrial countries—end-of-pipe treatment, relocation to the Third World, structural change in the industrial sector and even environmentally oriented modernization—have so far been unable to solve the problems of ‘dirty industries’, although some approaches have shown (some) promise.

    Notes: Abstract In this paper an analysis of the U.K. government's air pollution emissions policy for the residential sector is undertaken. The analysis covers emissions arising from water and space heating, electric appliances and cooking appliances. Using an integrated economic-engineering model, the effects of the Energy Savings Trust and the imposition of Value Added Tax on residential fuel will be evaluated in terms of energy consumption and pollution emissions. It is found that the initial proposed policy was not sufficiently stringent to meet the government's environmental objectives, and that subsequent events have undermined the government's programme even further. Unless alternative policies are introduced, emissions from the residential sector will play an important role in jeopardizing the ability of the U.K. government to meet its international obligations.

    Topics: Energy, Environment Protection, Nuclear Power Engineering , Economics
    Notes: Abstract Policy makers, industrialists and environmentalists express concern that the imposition of tough environmental policies in some countries displaces production, and hence pollution, to countries which impose less tough environmental policies. Yet empirical studies of such impacts suggest they are small. However, these findings are derived from models in which international trade is modelled as being perfectly competitive. In this paper I model trade as imperfectly competitive with scope for strategic behavior by producers, in this case investment in capital. I show that the choice of environmental policy instrument can have a marked impact on the incentives for producers to act strategically, with environmental standards significantly reducing the incentives for strategic overinvestment relative to environmental taxes or no environmental policy at all. Whether welfare is higher using standards or taxes depends on whether producing countries are also significant consumers of the polluting product, and on whether all producing governments act to reduce emissions or only some subset of governments. To assess the quantitative significance of these theoretical results I conduct policy simulations on a calibrated model of the world fertilizer industry. These simulations show that the impact of environmental policy on strategic behaviour can be large.

    Notes: Abstract The analysis of endogenous growth models with pollution often concentrates on steady state trajectories, under the assumption that the steady state is in some sense stable. In the present note we provide examples showing that this issue should be dealt with carefully. We use the Rebelo “Ak” model augmented with a stock of pollutants causing a negative externality. It is found that optimal growth is not necessarily balanced (contrary to the outcome of the standard Rebelo model). Moreover, the existence of the externality may affect long run optimal growth rates.

We illustrate the importance of an integrated approach by estimating costs and benefits of a proposed energy saving program for Hungary, originally designed to reduce CO2 emissions. The dominant benefit of implementing the program is likely to be reduced health damage from local pollutants. Also reduced costs of material damage and to a lesser extent vegetation damage contribute to make the net benefit considerable. Compared to the reduction in these local and regional effects, the benefits from reducing greenhouse gases are likely to be minor. Since local effects in general occur much earlier after measures have been implemented than effects of increased emissions of greenhouse gases, inclusion of local effects makes evaluation of climate policy less dependent on the choice of discount rate. In our opinion, similar results are likely for many measures originally designed to reduce emissions of greenhouse gases particularly in some areas in developing countries with high local pollution levels. Main uncertainties in the analysis, e.g. in the relationships between damage and pollution level, are discussed.

    Notes: Abstract Human perceptions of the relationship between pollution and food safety are often haphazard and contradictory, based on a variety of sources of information. Recent media events concerning seafood and coastal pollution have generated concern that an otherwise healthy food— fish and shellfish—has become dangerous. We assess consumer knowledge about seafood safety and coastal pollution using several methods, including tests of cultural consensus. We find that consumers view seafood as far more threatened by pollution than scientific analysis suggests, due in part to their perceptions about the dynamics of the marine environment. Finding variation in perceptions within our population based on income and other factors, we explore the use of the cultural consensus approach in large and heterogeneous populations.

    Notes: Abstract In 1986, the National Materials Exposure Programme was set up within the United Kingdom to investigate the effects of acid deposition on buildings and building materials. Thirty sites were chosen, which represented a range of geographical and pollution climates. Each site met a minimum meteorological and pollution monitoring regime (including SO2, NO2). After four years, other sites were included (with less frequent data collection) and some sites removed. At each site, samples of 3 types of stone, mild steel, painted steel, Cu, Al and galvanised steel were exposed, with some of the stone sheltered from direct precipitation. Samples were removed periodically for analysis and dose-response relations derived for different materials. The empirical relationships derived are in the form of: decay rate=a [SO+] + b [H2] + c [rainfall] + d These dose response relations have been used to develop critical load maps for materials for the United Kingdom. Eight years of data have been collected, some for the UNECE task force programme. Laboratory tests using an Atmospheric Flow Chamber were also undertaken. Since the beginning of the programme addition materials have been exposed on some sites including mortars. A further set of eight sites has been used to assess the effects of ozone on a range of organic materials (for example polyvinyl chloride, polycarbonate, sealants). The paper presents up-to-date findings for the programme and confirms the dominance of dry deposition of sulphur dioxide as the main decay process for sensitive materials in areas of significant pollution.

    Notes: Abstract Sandy soils, in the border area of Belgium and the Netherlands (the Kempen region), are heavily contaminated by atmospheric deposition of cadmium and zinc from nearby smelters. Groundwater contamination by leaching from these low retention soils is subject of study. There are reports of high cadmium and zinc concentrations in groundwater in the area, but in most cases the direct sources are unknown. In an attempt to predict present or future risk of groundwater contamination by soil leaching, metal binding processes (retardation) were studied that are specific for these soil types under the existing acidifying conditions. From four fields nine contaminated profiles were sampled and analyzed for cadmium and zinc. Average concentrations of 131 μg g-1 zinc and 1.6 μg g-1 cadmium with maximum values of 2989 μg g-1 respectively 16.3 μg g-1 were found. In addition pH and contents of organic matter, aluminium, iron, and manganese were determined. The relative importance of these soil parameters for metal retardation is derived from the profiles. The data show that organic matter is the most important soil component for binding cadmium and zinc. Adsorption of cadmium and zinc on aluminium, iron and manganese (hydr) oxides appears to be of minor importance at low pH (〈5.5).

    Notes: Abstract To examine the spatial variation of airborne lead in Taipei, a field study was conducted during the summer and fall of 1991. Samples were collected 2–4 times daily at several sites for the determination of airborne lead. Results indicate that the average of air lead concentration of Taipei city is 0.70±0.39 μg/m3 and eighty-eight percent of particles are smaller than 10 pm. From high to low polluted area, the fine particle concentrations are 0.83, 0.51, 0.29 μg/m3 The lead concentration of particulates 〈 10 μm on 2nd, 7th, and 14th floors of a building are 0.75, 0.60, 0.55 μg/m3, and appears to be little difference among vertical dispersions. The air lead concentrations (da 〈 10 μm) on roadside, side walk and covered walk way from the vehicle emission source of a main road are 0.83, 0.78, 0.87 μg/m3 the highest is on the covered walk way. For lead concentrations (da 〈 10 μm) on the main street, side street and alley of an area are 0.34, 0.37, 0.35 μg/m3 the result indicates lead concentrations on these pathways are not significantly different.

    Notes: Abstract In many forested wetlands of Louisiana, surface water quality is being deteriorated by nutrient input from adjacent agricultural production areas. This field study assesses the input of fertilizer N, applied to sugarcane fields, to forested wetlands. The potential use of natural abundance variations in 15N14N ratios for identification and tracing surface water N sources (NH 4 + - and NO3 --N) was evaluated. Runoff and surface water samples were collected from sugarcane fields and bordering forested wetlands (6 stations) over a 16 month period and analyzed for NH 4 + -N, NO 3 - -N, and associated NH 4 + -δ15N and NO 3 - -δ15N ratios. Fertilizer N draining into adjacent forested wetland was estimated to be only a small fraction of the amount applied. Concentrations of NH 4 + - and NO 3 - -N in the collected water samples were low and ranged from 0.02 to 1.79 mg L-1. Isotopic analysis revealed NH 4 + -δ15N and NO 3 - -δ15N means were distinctive and may have the potential to be used as tracers of N contamination. The mean NH 4 + -δ15N value was +18.6 ± 7.1‰ and the NO 3 - -δ15N mean was +8.3 ± 3.1‰. Anomalously high NO 3 - -δ15N values (〉30‰) were attributed to denitrification.

    Notes: Abstract A combined statistical and computergraphic approach is proposed for apportionment and attribution of soil contaminants in complex areas. The field test site lies north of Swansea, south Wales and contains two major pollutant sources, an active nickel refiner and (4 km away) the site of major base metal smelting in the nineteenth century (the Lower Swansea Valley reclamation study area). Soil samples (70 samples, 0–15 cm) were collected on a regular grid of 1000 m interval. They were extracted using 0.05 M diammonium EDTA and the extracts analysed for Cd, Co, Cu, Fe, Mn, Ni, Pb and Zn. Soil pH and %organic content were also determined. Factor analysis yielded three groups which explained 73.8% of the data variance (1: Cd, Cu, %OM, Pb, Zn, Ni; 2: Cd, Zn, Mn, pH; 3: Cu, Mn, Co, Ni, Fe). Isoline plots were classifiable into the same three groups. It was concluded that factor 3 contained those elements associated with smelter emissions, factor 1 with contamination from the Lower Swansea Valley and in factor 2 pedogenetic processes control the occurrence of the elements.

    Notes: Abstract The Tagus estuary, located at the western Iberian coast in front of Lisbon is the largest one in Portugal, where it drains highly populated and industrialised regions. The amount of sediment transported by this river is so great that the submarine delta is one of the largest in the Iberian margin, very well defined and reaching the 70m isobath. The geochemical pattern of the muddy deposit off the Tagus river has been determined by elemental analyses of bulk surficial sediments, collected at the Portuguese margin adjacent to the Tagus estuary. Measurements were carried out by energy-dispersive X-ray fluorescence spectrometry (EDXRF). Sediments were usually composed of fine particles (silts and clays) and were high in organic matter (measured as loss on ignition). Elemental concentrations for Zn and Ph clearly indicate an estuarine contamination probably associated with discharges from urban centers or due to the influence of the industries located downstream. apparently the depletion on the Cu contents is caused by its release (soluble complexes) into the marine environment. Variations observed in the elemental distribution of the sediments of the Tagus with distance from the estuary seem to be dependent on the grain size distribution related to the dynamics of the sediment transport.

    Notes: Abstract Environmental Ethics is the ethics of how we humans are to relate to each other about the environment we live in. The best way to adjust inevitable differences among us in this respect is by private property. Each person takes the best care of what he owns, and ownership entails the free market, which enables people to make mutually advantageous trades with those who might use it even better. Public regulation, by contrast, becomes management in the interests of the regulators, or of special interests, such as lovers of rare species-not the people they're supposed to be serving.

    Notes: Abstract The isotopic composition of lead pollution in the environment provides information as to the source of emission. The 206Pb/207Pb ratio for Canadian industrial emissions (1.153±0.005) is significantly less than U.S. industrial emissions (1.213±0.008) making it possible to determine the relative contributions of emissions from both countries within Eastern North America by means of a simple isotopic mixing model. Profundal sediments in lakes chronicle contaminant inputs and are therefore useful monitors of environmental pollution. Surface sediment from 32 sediment cores across Quebec and Ontario, Canada were analyzed for 206Pb/207Pb to ascertain the relative proportions of Pb emission from Canada and the U.S.A. Data show that U.S. contributions to the total lead burden in surficial sediments across much of southern Quebec and Ontario are often in excess of 50%. Local sources were particularly important in the Eastern Township region of Quebec which lies 200 km south east of the city of Montreal. The results are discussed in relation to the major sources of industrial lead emissions in North America.

    Notes: Abstract Elevated phosphate concentrations at Safaga and Quseir, Red Sea, Egyptian coast, wererelated to some ecological and nutritional aspects of the macro-alga Cystoseira myrica during1985. The results obtained were compared with those recorded for a non-polluted control site atGhardaqa. Chemical analysis of surface seawater samples revealed that the concentrations of dissolvedphosphate at Safaga and Quseir were 3 and 20 times as much as that at Ghardaqa, respectively.The standing crop of C. myrica showed two peaks in spring and autumn. Maximum biomass yield(491 g m-2) and number of individuals (127 m-2) of C. myrica were recorded in the spring at theGhardaqa site. Quseir C. myrica samples contained significantly higher protein-N, total-N andtotal-P values but lower carbohydrate values than the Safaga and Ghardaqa samples (LSD at 1%level). Tissue N:P molar ratios for C. myrica, Laurencia papillosa and Ulva lactuca collected fromGhardaqa ranged from 68-98, compared to 30-59 for the same species collected at thephosphorus polluted sites at Safaga and Quseir. The carbon levels and the C:N ratios of C. myricaexhibited no significant variations in the three studied sites. However, the C:P ratios of Ghardaqaplants were significantly higher than those of Safaga and Quseir.

    Notes: Abstract A fugacity-based model to explain the partitioning of contaminants in the environment is evaluated. Using emission inventories, air and water concentrations predicted by the model for the southwestern Québec region generally agree with field data for phenanthrene, α-HCH, lindane, and DDT. For pyrene, air concentrations are in agreement but water concentrations were in error by a factor of nearly 20. There is also a possibility for using the model to predict emissions from known air and water concentrations. The model was run over 120 times each for phenanthrene, HCB, and lindane while randomly varying the input parameters each time. A Principal Components Analysis and a partial correlation analysis indicate that certain input parameters are more important for some compounds than for others and that log Kow is the physical-chemical property of greatest importance.

    Notes: Abstract Organisms sensitive to ambient environment are used as bioindicators in monitoring pollution. The present investigation is designed to measure the extent of mercury and organomercury levels in selective biota of different trophic levels inhabiting in the coastal environment of Sunderban Biosphere Reserve, eastern part of India. The primary objective of this work is to provide baseline data for future environmental quality programme and to ascertain the suitability of these organisms to be used as bioindicator species of pollution. The seagrass (Porterasia coarctata), macrobenthos (polychaetes, gastropods and bivalve molluscs) and pelagic finfishes were collected from sites of different physiochemical characteristics. Concentration of total mercury was determined by cold vapour atomic absorption spectrophotometry technique (CVAAS) using a Perkin-Elmer 2380 AAS equipped with MHS 10. Both mercury and organomercury levels showed considerable interspecific and regional variations which reflected the feeding strategy of these animals and also the location of stations. The bivalve molluscs showed a high degree of organ-specificity in accumulation which might be attributed to the ion exchange activity of mucous membrane covering gill and mantle. Mercury levels in various compartments did not reveal any regular temporal variations but showed a slight increase in the late monsoon months indicating the apparent influence of river run-off and reduction in salinity in the ambient medium. A continuous monitoring programme is recommended in order to clarify the present trend and to establish the studied organisms as indicator species.

    Notes: Abstract We used flow cytometry (FCM) to conduct a multiple-tissue assay on slider turtles (Trachemys scripta) inhabiting radioactive seepage basins. Duplicate samples of blood, heart, spleen and kidney were analysed on two different cytometers (Leitz MPV and Coulter Profile II), each employing distinct staining protocols (DAPI and PI, respectively). Both DAPI and PI assays of spleen cells demonstrated significantly greater variation in DNA content for the basin turtles than for ‘control’ animals from nearby, uncontaminated sites. Basin turtles also exhibited significant cell-cycle effects for blood and spleen, again revealed by both assays. These corroborative findings demonstrate the consistency and repeatability of FCM assays in environmental monitoring and identify the particularly sensitive nature of turtle blood and spleen to mutagenic agents. Our survey complements previous FCM studies on sliders from contaminated sites and thereby underscores the species' potential as a sentinel for biomarker assays.

    Notes: Abstract Earlier studies have shown that elevated levels of Cd may negatively affect the behaviour of birds and mammals. However, these experiments were carried out under controlled laboratory conditions, and results from free-living populations have not been available. By using osmotic minipumps implanted subcutaneously in free-living willow ptarmigan hens, the effects of Cd contamination on parental behaviour were studied. When CdCl 2 (83.2 mg Cd/l) was administered, an increase in the Cd content in the liver and kidneys was achieved that was comparable to normal field levels. After hatching, the hens were followed by radio telemetry and parental behaviour was recorded when the broods were flushed. Chick survival up to 8–9 days was recorded. Cd-contaminated hens showed less distraction display and flew longer when flushed compared with control hens, although not significantly so. The Cd-contaminated hens had significantly lower chick survival than control hens.

    Notes: Abstract Manipulative experiments in the field are important tools, for improving understanding of disturbances, such as contaminants, causing environmental impacts. We tested a method to create patches of increased concentrations of metals in intertidal sediments. The method produced persistent concentrations of metals, which were as large as those observed in contaminated areas and it appears to be applicable in different habitats. The utility of this technique as a tool to improve predictions about environmental effects needs to be evaluated by repeated experimentation.

    Notes: Abstract Ground running invertebrates were sampled by pitfall trapping in woodlands with high and low aerial pollution by heavy metals. Principal component analysis calculated for the environmental variables showed degree of metal contamination to be the most important difference between the sites. Calculation of canonical correspondence analysis (CCA) for different groups of animals e.g. Diplopoda, Opiliones, Aranaea and Carabidae was carried out and produced plots which can be interpreted with respect to the pollution effect. The effect of different environmental factors on individual species or subgroups delimited by size, breeding season, diet etc. was determined. Species associating with or disassociating from high pollution levels can be identified. No clear patterns were shown when examining size or breeding season in Carabids in relation to pollution. The highly polluted woods near the main pollution source at Avonmouth are lacking in lycosid spiders, the vacant niche may be filled by a large species of ground running agelenid which may be more adaptable in habits than the lycosids. CCA plots of both Aranaea and all species pooled together show a triangular shape. This is interpreted as representing a small number of species able to adapt to high pollution levels and a larger potential number found at ’clean' sites.

    Notes: Abstract The space-time distribution of some pollutants (Cu, Pb, Zn, Cd, Fe, Mn, V, Ni, Cr) in the sludge of the canals of Venice was studied. The contamination levels were comparable to, or higher, than those measured in the most polluted sediments of the Lagoon of Venice. Sediments were collected by two different sampling techniques: 1) collection of sediment cores (upper 5 cm) by a syringe-type corer; 2) collection by traps, placed on the bottom of the canal. Traps permitted the sampling of sediments essentially resuspended by overlying water turbulence. This sediment fraction is subjected to variations of its physicochemical parameters (principally change of redox conditions) and therefore to pollutant exchange at the water/sediment interface. The metals principally exchanged during sediment resuspension were Cd, Pb, Zn and Cu. These metals have principally an anthropogenic origin and are bound to the most labile geochemical phases of the sediment (such as sulphides), which can be oxidised during sediment resuspension, releasing metals into the water. Fe, Cr and Ni were only partially exchanged, while Mn and V were generally not exchanged; a significant fraction of these metals is of natural origin and is bound to the most refractory phases of the sediment.

    Notes: Abstract Elevated phosphate concentrations at Safaga and Quseir, Red Sea, Egyptian coast, were related to some ecological and nutritional aspects of the macro-algaCystoseira myrica during 1985. The results obtained were compared with those recorded for a non-polluted control site at Ghardaqa. Chemical analysis of surface seawater samples revealed that the concentrations of dissolved phosphate at Safaga and Quseir were 3 and 20 times as much as that at Ghardaqa, respectively. The standing crop ofC. myrica showed two peaks in spring and autumn. Maximum biomass yield (491 g m−2) and number of individuals (127 m−2) ofC. myrica were recorded in the spring at the Ghardaqa site. QuseirC. myrica samples contained significantly higher protein-N, total-N and total-P values but lower carbohydrate values than the Safaga and Ghardaqa samples (LSD at 1% level). Tissue N:P molar ratios forC. myrica, Laurencia papillosa andUlva lactuca collected from Ghardaqa ranged from 68–98, compared to 30–59 for the same species collected at the phosphorus polluted sites at Safaga and Quseir. The carbon levels and the C:N ratios ofC. myrica exhibited no significant variations in the three studied sites. However, the C:P ratios of Ghardaqa plants were significantly higher than those of Safaga and Quseir.

    Notes: Abstract A study was carried out recently to determine the pollution level of waters in the Karachi harbour and adjoining backwaters. Nine locations were selected, four in the backwaters, two on the seaside, and three in the main navigable channel. Four of these locations were deliberately selected to coincide with those of a previous study conducted in 1982 by Pakistan Council of Scientific and Industrial Research (PCSIR) so that the values for the concentration of different pollutants could be compared. Analysis was conducted for pH, bicarbonates, Total Solids, Volatile matter in Total Solids, Chlorides, Sulphates, Calcium, Magnesium, Sodium and Potassium. The results indicate that the composition of sea water as far as the concentration of above constituents is concerned has not changed much since the time of the PCSIR study, viz 1982, except that the organic matter concentration has increased. The reasons for this increase in organic loading and its possible impact are discussed in this paper.

    Biological Indicators of Marine Environmental Health: Meiofauna – A Neglected Benthic Component? (1999)

    Notes: Abstract This paper considers the use of meiofauna (benthic metazoa 45 to 500 μm in size) as biological indicators for monitoring marine environmental health. To date, this abundant and ubiquitous group of invertebrates has been largely neglected in applied sampling programmes; instead, emphasis has been placed upon more conspicuous biological components such as seagrass, macrofauna and epiphytes. In an attempt to redress this balance, this paper sets out three objectives: (1) to explain the reasons for selecting biological response indicators from across the whole spectrum of phylogenetic organisation, (2) to summarise those aspects of meiofaunal life-history and demography that render this group suitable for monitoring anthropogenic pollution and disturbance, (3) to suggest how to optimise the inclusion of meiofauna in monitoring programmes so that they provide maximum information for management purposes. To achieve these objectives the environmental impact assessment framework of Ward and Jacoby (1992) is adopted as a matrix into which the relevant components of meiofaunal ecology are fitted. Using this matrix, meiofauna are shown to have advantages that include their sessile habit, high species diversity, short generation time, direct benthic development and ubiquitous distribution. Disadvantages include their small size, high level of spatial and temporal variability, the potential cost of sample processing and the limited taxonomic literature accessible to non-specialist workers. The paper concludes with a discussion of sampling strategies and methods of analysis that may be used to efficiently incorporate meiofauna as biological response indices into environmental monitoring. Emphasis is placed on cost-effective techniques such as taxonomic minimalism.

    Notes: Abstract Results of magnetic susceptibility mapping around a coal-burning power plant were used to verify the field in situ measurements with data acquired in laboratory on soil samples collected at approximately the same measurement grid sites at different distance from the source. This comparison enables quantifying the field data obtained using the Bartington MS2 meter and to relate them, at least approximately, to mass specific values. Moreover, it is shown that certain diversity in the grid points of field measurements and soil sampling can slightly bias the field measurements. However, this shift is of minor significance and Bartington field readings can be considered as reliable.

    Notes: Abstract The long-term study objective was to determine the suitability of selected species of genus Pinus (Pinus sylvestris, Pinus nigra and Pinus mugo) for use as bioindicators of environmental pollution. In these experiments a new methodology of evaluation of mitotic abnormalities was established and its potential for common use tested. The study confirmed three species of genus Pinus as suitable bioindicators. The results also indicate that trees may show adaptive changes in response to severe pollution stress.

    Redistribution of Mercury from Contaminated Lake Sediments of Clear Lake, California (1998)

    Notes: Abstract Mining operations conducted at the Sulphur Bank Mercury Mine at Clear Lake, California, from 1872–1957, together with acid mine drainage since abandonment, deposited ca. 100 metric tons of mercury (Hg) in the sediments of Clear Lake. In 1992 Hg in surficial sediments (up to 183 mg kg-1 total Hg and 15.9 μg kg-1 methyl Hg) exhibited a classic point source distribution with maximum concentrations adjacent to the mine. However, the ratio of methyl:total Hg in sediments increased with distance from the mine, suggesting either differential transport of methyl Hg or a non-linear relationship between sediment inorganic Hg concentrations and methylation. Water exhibited an even more gradual decline in total Hg concentrations with distance from the mine, in both unfiltered bottom water (max. ca. 70 ng L-1) and filtered surface water (max. ca. 7 ng L-1). In comparison with other studies, Clear Lake exhibits high total Hg in sediment and water, yet relatively low methyl Hg concentrations. Our findings indicate a non-linearity between total and methyl Hg concentrations in sediments. The ratio of methyl:inorganic Hg is approximately 2 orders of magnitude higher in the water column than in the sediments, making the methyl fraction much more available for down-gradient transport away from the mine. Particulate Hg comprises ca. 33–94% of the total Hg and ca. 25–78% of the methyl Hg in the water column. Geothermal springs do not appear to represent a significant source of Hg to Clear Lake. The present pattern of Hg distribution in Clear Lake shows that water column transport plays some role in the lake-wide contamination of methyl Hg, but high methylation at relatively low inorganic Hg concentrations cannot be ruled out. No quantitative estimate of the area of sediments requiring remediation is possible from these descriptive data alone.

    Notes: Abstract Changes of phenolics and chemical elements [nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), manganese (Mn), iron (Fe), boron (B), copper (Cu), zinc (Zn), lead (Pb), cadmium (Cd), chromium (Cr), nickel (Ni) and cobalt (Co)] content in needles of black pine ( Pinus nigra) as dependent on age of needles (5–6 classes) and pollution were examined. The content of ortho-diphenols (o-dPh) and total phenols (TPh) was significantly higher at a polluted site than at a control one. It increased with age of needles at both sites. At the polluted site contents of N, K, Mg in black pine needles were lower and of Fe, Ni and F were higher than at the control site. An increase of content with age of needles at both sites was detected for Ca, Fe, B and F, and a decrease for N, P, K, Cu and Ni. The content of elements in different age classes of needles is connected with their mobility. The content of phenolics is negatively correlated with main nutrients and positively with some toxic elements.

    Notes: Abstract The physico-chemical characteristics of the groundwater of the Temara aquifer were studied by means of piezometric mapping and determination of the ionic composition of the groundwater. In general, the agricultural activity is intense in the area, with water being pumped from numerous wells. Two aquifer formations can be distinguished which, over a wide area, are separated by layers of low permeability. The increased salinity at some points of the coastal zone is probably linked to the combined action of the washing out of Miocene marls, dissolution of carbonate rocks, agricultural pollution and seawater intrusion.

    Notes: Abstract The photosynthetic and respiratoric capacity of Fucus vesiculosus grown at three different levels of salinity (4.5, 8 and 20‰) was studied in the presence of different concentrations of lead (5, 10, 15, 20, 25, and 30 mg PbCl2 L−1). The studies were performed by using a light-pipette, which has a precisely defined light source of photosynthetic active radiation (PAR, 400–700 nm). The photosynthetic and respiratoric capacity of the algae were measured when exposed to light pulses with increasing irradiance and after 24 hr in seawater with the addition of lead. The results indicate that the photosynthetic capacity of F. visiculosus from 20‰ is more sensitive to lead compared to those from 8 and 4.5‰. The photosynthetic capacity was reduced by 69% at 30 mg PbCl2 L−1 compared to the control alga. The photosynthetic capacity of F. vesiculosus from 8 and 4.5‰ was reduced by 38 and 15%. The respiratoric capacity of F. vesiculosus from 20‰ was reduced by 41% at 30 mg PbCl2 L−1. However, the respiratoric capacity of the algae from 4.5‰ increased by 55% at the same concentration of PbCl2. The results indicate that lead showed inhibitory effects on photosynthesis but a stimulatory effect on respiration of F. versiculosus grown at low levels of salinity.

    Notes: Abstract The Geological Surveys of Finland and Norway, and the Central Kola Expedition, Russia, carried out an environmental geochemical mapping project, including investigation of stream water quality. The project was carried out in 1992–1993 in the border areas of Finland, Norway and Russia, covering an area of 12 000 km2, to determine the impacts of smelting industries at Nikel and Zapoljarnij. Stream water was one of eight different indicators providing an estimation of the degree and distribution of contamination in the study area. Contamination of surface water was assessed by analyses of 44 samples, 41 variables were measured on each sample. Indicators of human activities in surface waters are NO3, K, electrical conductivity (EC), SO4, Na, Cl and acidification indicated by alkalinity and pH. On the coast Na and Cl contents are also affected by marine salts. The results show considerably higher contents of K, Ca, Mg, SO4, Na, heavy metals and EC in the samples close to Nikel and Zapoljarnij smelters than those sites more distant from the polluting sources. Especially chemical effects of high emissions of Ni, Cu and SO2 on stream water quality from Nikel and Zapoljarnij smelters are clearly seen near the sources of emissions.

    Notes: Abstract The properties of stable oxygen isotopes make them useful for studying processes involved in the atmospheric oxidation of sulphur compounds. Experimental work in the 1980s reported that the formation of primary combustion sulphates by high temperature oxidation of SO2(g) to SO4 leads to δ18OSO4 values between +40 and +45‰. This study reports sulphate oxygen isotopic compositions from precipitation events collected at two sites in eastern Newfoundland. Values as high as +41.7‰ were measured in natural precipitation samples collected near a small oil-fired power plant located on the campus of Memorial University of Newfoundland in St. John's. These values are higher by 16‰ than any previously reported for precipitation in the literature and in conjunction with other chemical data implicate the power plant as the pollution source. Values from the second site (Seal Cove) were similar to previously reported ranges for precipitation, despite its proximity to a much larger oil-fired, thermal generating station, suggesting that different oxidation mechanisms were dominant there. Oxygen isotopic compositions of precipitation sulphates can be an important complementary tool to other isotopic, trace metal and meteorological analysis in the tracing of sources of atmospheric sulphur compounds.

    Notes: Abstract Tropospheric ozone is considered as the major pollutant of concern to the health and productivity of forests in the eastern United States and has more recently become of increasing concern within the forests of southern Europe. Recent observations have clearly demonstrated foliar injury symptoms to be occurring on many tree and native plant species within remote forested areas. Several plant genera (and a few species within genera) found in both the forests of Switzerland and the southern coastal region of Spain exhibit field symptoms typical of ambient ozone exposures. Ozone exposures for many species have been conducted under controlled CSTR conditions and within open-top chambers within the study areas. Results have confirmed that the O3-like foliar symptoms as observed under natural forest and open grown conditions for many native tree, shrub, and herbaceous species in Spain and Switzerland are caused by exposures to ambient O3.

    Notes: Abstract Needle fluctuating asymmetry (FA) in Scots pine (Pinus sylvestris) was studied south of the Severonikel nickel-copper smelter in the Kola Peninsula, Russia. We measured the difference in length of two needles of the same pair, and calculated FA as the ratio between this difference and the average length of the two needles of this pair. Needle FA did not depend on tree age, distance from the nearest neighbour or branch position within the crown, but increased with an increase in branching order. Needles originating in different years (1993-1997) demonstrated among-year variation in FA, which, however, was not related to annual fluctuations in SO2 emission by the smelter. FA increased with decreasing distance from the smelter, and in the sites proximate to the smelter FA was double that found at the most distant (background) sites. The increase in FA was primarily due to an increased difference in the length of the two needles, and this difference may serve as a practicable indicator of pollution-induced stress in Scots pine.

Additionally, comparisons of dry weight rates obtained with two different diameter (4.0 and 7.6 cm) traps of the same aspect ratio (6), at four different depths below the epilimnion, and from the lake's two basins, in 1993, are presented to establish the representativeness of the long-term data. The near equivalence of fluxes determined with the different size traps and cumulative deposition rates measured over the range of deployment depths, and the minor differences in flux observed for the two basins, supports the representativeness of long-term data in quantifying deposition rates for the pelagic zone of the lake. Short-term variations in downward flux have been common in the lake over the period of monitoring. The summer-average dry weight deposition rate decreased systematically (by about 45%) following the closure (in 1986) of a soda ash facility that caused enhanced rates of calcium carbonate deposition; from an average of 23.2 to 12.8 g m-2 d-1. These dry weight deposition rates are high compared to values reported in the literature for other lakes, and are responsible for the lake's high rate of net sedimentation.

    Notes: Abstract In recent decades, SO4 2- concentrations have increased in groundwater and surface water of freshwater wetlands. For many minerotrophic peatlands, S originating from SO4 2--polluted groundwater and surface water is a more significant source of SO4 2- than the actual atmospheric deposition of S compounds. Lowered groundwater tables in wetlands, as a result of either natural or anthropogenic desiccation, may cause acidification because of concomitant geochemical oxidation processes. The impact of the enhanced availability of reduced S compounds, due to preceding SO4 2- pollution, on these processes was tested in a mesocosm experiment, using soil cores including vegetation from a mesotrophic wet meadow. The soils had been maintained in waterlogged condition for seven months, using two environmentally relevant SO4 2- concentrations (2 and 4 mmol L-1). The groundwater table was reduced in two successive steps: 10 cm below soil surface, and complete desiccation. Control pretreated soils did not show a decrease in soil pH during desiccation, due to adequate buffering by bicarbonate. However, both SO4 2--pretreated groups showed a significant drop in pH (from 6.5 to 4.5) caused by additional sulfide oxidation, leading to high SO4 2- concentrations (10 and 16 mmol L-1, respectively). Cation exchange and acidification-related solubilization processes induced the mobiliztation of base cations and potentially phytotoxic metals like Al. Nutrient concentrations in soil moisture were influenced strongly by SO4 2- pretreatment, showing distinct patterns for P, N and K. Therefore, S polluted groundwater and surface water may severely increase the sensitivity of wetlands to desiccation. The results are discussed in relation to wetland management.

    Notes: Abstract The toxic effect of multi metals mixture which exist simultaneously in aquatic ecosystem on natural phytoplankton assemblages (green algae, blue-green algae and diatoms) was studied. For this purpose a laboratory scale unit was designed to evaluate the effect of continuous flow metals mixture in forms if triple and penta metals in Nile water algae. Clear changes in algal biomass in terms of chlorophyll a (chl a) took place when subjected to metals combination. The rise or decline in chl a was in relation with other algal pigments (chl b, chl c, carotenoides and phenophytin), protein and carbohydrate content of algal cells. Substantial changes in phytoplankton community structure was detected and the most tolerant group was blue-green algae followed by green algae while diatoms was the most sensitive group. The most dominant species in all cases were blue-green alga Oscillatoria mougeotii and green alga Scenedesmus quadricauda. In addition clear changes in morphological shape was observed for tolerant species belonging to the three algal groups. Nile water algae has ability to remove and accumulate metals in the following order therefore Zn 〉 Cd 〉 Ni 〉 Cu 〉 Cr. In addition, phytoplankton has ability to recovered from the stress of metals when eliminated from the media and the recovered biomass was nearly equivalent to that before exposing to metals stress. The overall effect of metals mixture depending on the type and number of metals, the algal community structure and ratio between different morphological forms of algae (unicellular, colonial and filamentous).

    Environmental Policy, Tax Incidence, and the Cost of Public Funds (1999)

    Notes: Abstract This paper studies under what conditions a ‘double dividend’ may occur in the sense that both environmental quality and employment rise. A simple static general equilibrium model is employed in which tax policy faces the dual task of internalising a negative environmental externality and raising revenue to finance public consumption. The model features a clearing labour market with both labour demand and supply and a fixed factor of production (e.g. capital). Hence, we can study tax incidence and its effect on employment, environmental quality, and the marginal cost of public funds. It is shown for the case of an upward sloping labour supply curve and less than full tax shifting by employers that a shift towards greener preferences cannot yield a double dividend, even if the fixed factor is important. However, if labour supply curve bends backwards, more environmental concern confers a double dividend.

    Disutility of pollution and endogenous growth (1995)

    Notes: Abstract Endogenous growth is generally built on a positive externality hypothesis which is the opposite of a negative externality caused by pollution. We study a linear technology with simple assumption: an aggregate capital stock which represents a learning by doing effect and a pollution flow proportional to production. In this framework, we analyse the precise effects on growth of the disutility of pollution and its interaction with the utility of consumption in an economy without abatement technology. The decentralized equilibrium always leads to unlimited growth, but optimal growth is often limited (the negative effect of pollution dominating the positive effect of learning by doing). In this case, the optimal policy which leads the decentralized economy to follow the optimal growth path is to tax capital; in contrast with the optimal subsidy policy in an economy without pollution. When an abatement technology is introduced, the optimal solution can lead the economy to unlimited growth, whatever the form of the utility function.

    Notes: Abstract This article concerns itself with the environmental role of heavily polluting industries since 1970, analysing its development in 11 basic industries, as well as electricity production and road transport, in 32 industrial countries. It argues for a green industrial policy, demonstrating that other mitigations of environmental pressure in industrial countries – end-of-pipe treatment, relocation to the Third World, structural change in the industrial sector and even environmentally oriented modernization – have so far been unable to solve the problems of ‘dirty industries’, although some approaches have shown (some) promise.

    Notes: Abstract We investigate the welfare effects of environmental tax reform, i.e. raising environmental taxes and using the proceeds to reduce distortionary taxes on labour. The framework of analysis is a small open economy with involuntary unemployment due to a rigid consumer wage. Environmental tax reform boosts not only environmental quality but also employment if substitution between labour and resources is easy, the production share of the fixed factor is large, and the initial tax rates on resources and profits are small. If the initial tax system is sub-optimal with a negligible tax on resources, profits rise as well.

    Notes: Abstract The powerful mass-flow of melt water during the brief period of spring thaw provides a surge of pollutants and causes extremely toxic short term conditions. Together with the increase in total metal concentrations during this period, a redistribution in metal speciation occurs that increases the proportion of more toxic forms. Concentrations of ion-exchangeable fractions of nickel (Ni), copper (Cu), aluminium (Al), and manganese (Mn) show strong negative correlations with pH. The sum of complex metal species shows a strong positive correlation with total organic carbon (TOC). A data analysis model based on relationships observed between key parameters and metal behaviour together with gidrological data allowed an assessmrnt of the metal impact on waterbodies from accumulated airborne pollution (Ni, Cu) as well as from accelerated leaching from watersheds (Al, Mn).
