    Notes: Abstract During the last decade an increasing amount of studies have investigatedthe relationship between air pollution and human health effects. In thisstudy we investigate how these effects in turn induce reduced labourproductivity in terms of sick-leaves, which is an important factor inassessment of air pollution costs in urban areas. For this purpose weemploy a logit model along with data on sick-leaves from a large office inOslo and different air pollutants. Our results indicate that sick-leaves aresignificantly associated with particulate matter (PM10), while theassociations with SO2 and NO2, are more ambiguous. We also tryto estimate the induced social costs in terms of lost labour productivity andincreased governmental expenditures, although these estimates are moreuncertain.

    Notes: Abstract This paper examines the impact on air pollution ofchanges in the composition of manufacturing output indeveloped and developing countries. Pollutionemissions from manufacturing output are estimated ina manner which holds constant the effect of technologyand regulations allowing the impact of compositional changes alone on pollution to beestimated. The paper has three main findings; (1) theinverted-U estimated between per capita income and thepollution intensity of GDP arises due to both thecomposition of manufacturing becoming cleaner and theshare of manufacturing output in GDP falling.Compositional changes alone are not responsible forthe inverted-U between per capita income and percapita emissions; (2) changes to the composition ofmanufacturing output are consistent with the pollutionhaven hypothesis, however there is clear evidence thatrising per capita incomes are associated with afalling income elasticity of demand for `dirty'products. This fact may explain the compositionalchanges that occur with development; (3) in additionto the income elasticity effect, the analysis suggeststhat land prices and to a lesser extent the prices oflabour and capital, determine the proportion of dirtyindustry within a country's manufacturing sector.

    Notes: Abstract The ozone forming potential of VOCs and NOx for plumes observed from several cities and a power plant in eastern Germany was investigated. A closed box model with a gas phase photochemical reaction mechanism was employed to simulate several scenarios based upon aircraft observations. In several of the scenarios, the initial concentrations of NOx, VOCs, and SO2, were reduced to study the factors limiting the O3 production. Ozone production was limited by the initial VOC concentrations for all of the simulated plumes. Higher O3 concentrations were produced with reduced initial NOx. In one sample with high SO2 mixing ratios (〉100 ppb), SO2 was also identified as a significant contributor to the production of O3.

    Notes: Abstract A group of 50 inexperienced scorers were asked to estimate –using standard reference photos – foliar injury induced by the gas pollutant ozone on the supersensitive indicator planttobacco (Nicotiana tabacum L.) cv. Bel-W3. Theaverage accuracy level was 56.1% (95.9% when theclasses nearest to the reality were also consideredcorrect) and the average repeatability was 65.4%. Theextreme classes were easily scored. Central classesproved to be more difficult to be evaluated: this maydepend on the fact that two leaves may have similaractual total injured area, but substantially differentnumbers and spatial distribution of the lesions. Insome cases we observed a prevalence of overestimationerrors in the high classes and underestimation in thelow classes: this is in contradiction with theWeber-Fechner law. It is noteworthy the very shorttime required by operators to score, regardless of the results.

    Notes: Abstract A quantitatively robust yet parsimonious air-quality monitoring network in mountainous regions requires special attention to relevant spatial and temporal scales of measurement and inference. The design of monitoring networks should focus on the objectives required by public agencies, namely: 1) determine if some threshold has been exceeded (e.g., for regulatory purposes), and 2) identify spatial patterns and temporal trends (e.g., to protect natural resources). A short-term, multi-scale assessment to quantify spatial variability in air quality is a valuable asset in designing a network, in conjunction with an evaluation of existing data and simulation-model output. A recent assessment in Washington state (USA) quantified spatial variability in tropospheric ozone distribution ranging from a single watershed to the western third of the state. Spatial and temporal coherence in ozone exposure modified by predictable elevational relationships (∼ 1.3 ppbv ozone per 100 m elevation gain) extends from urban areas to the crest of the Cascade Range. This suggests that a sparse network of permanent analyzers is sufficient at all spatial scales, with the option of periodic intensive measurements to validate network design. It is imperative that agencies cooperate in the design of monitoring networks in mountainous regions to optimize data collection and financial efficiencies.

    Notes: Abstract Norwich is the eastern most city in the United Kingdom. Despite a population of only 100,000 and very little local industry, studies have shown that the city experiences levels of nitrogen dioxide, ozone, particulates and sulphur dioxide exceeding the UK Air Quality Standards. Because of Norwich's situation within a large, predominantly rural area a large non-resident workforce is one factor that contributes to large, often very congested traffic flows. The city's location close to the European mainland also exposes it to polluted airmasses transported from the continent, especially in the case of particulates and ozone. In order to assess the relative contributions of local and regional sources, data from rural and urban monitoring sites are to be used in conjunction with ADMS-Urban and the UK Meteorological Office's NAME model.

    Notes: Abstract Different urban air pollution problems deal with complex structure of air flows and turbulence. For such problems the Computer Fluid Dynamics (CFD) methods become widely used. However, this approach despite a number of advantages has some problems. Experience of use of CFD tools for development of models and suggestions of their applications for a local scale air pollution over a complex terrain and stable stratification are discussed in this paper, including: • Topography and complex geometry: choose of the co-ordinate system and computer grid; • Turbulence closure for air pollution modelling: modified k-ε model for stable stratified ABL; • Boundary conditions for vertical profiles of velocity for stable-stratified atmosphere; • Effects of the radiation and thermal budget of inclined surfaces to dispersion of pollutants; • Artificial sources of air dynamics and circulation. Some examples of CFD applications for air pollution modelling for a flat terrain, mountainous area, mining open cast and indoor ventilation are discussed. Modified k-ε model for stably-stratified ABL is suggested. Due to the isotropic character of the k-ε model a combination of it in vertical with the sub-grid turbulence closure in horizontal can be more suitable for ABL. An effective scheme of boundary conditions for velocity profiles, based on the developed similarity theory for stable-stratified ABL, is suggested. Alongside with the common studies of atmospheric dispersion, the CFD methods have also demonstrated a good potential for studying anthropogenic and artificial-ventilation sources of air dynamic and circulation in local-scale processes of air pollution.

    Notes: Abstract The draft of the German guideline to calculate automobile exhaust dispersion is explained. It contains a two-stage-system: For first quick estimates the guideline contains the simple models MLuS and STREET. In case these models are not applicable or their results shows concentration levels close to the air quality standards, the more complex models PROKAS_V and MISKAM are recommended. PROKAS_V is a Gaussian plume model, MISKAM is a 3-dimensional microscale non hydrostatic flow model for built-up areas with an Eulerian dispersion model. The guideline comprises cases in rural areas without or with few adjacent buildings as well as urban areas with buildings near the roads. The contribution gives information about the models, typical results and some of the problems showing up presently.

    Notes: Abstract The personal exposure of children aged 9 – 11 years to particulate matter (PM10 and PM2.5) was carried out between January and September 1997 in the London Borough of Barnet. Personal sampling along with home, garden and classroom microenvironmental monitoring was completed for all ten children. Each child was monitored for five days during winter, spring and summer. All children completed daily time activity diaries to provide information on any potential activities that could influence their exposure to particulate matter. Each evening a household activity questionnaire was also completed by the parents. Personal Environmental Monitors were used to sample personal exposure to PM10 and PM2.5. Harvard Impactors were used for the microenvironmental sampling of both size fractions. The children's mean personal exposure concentrations for PM10 during winter, spring and summer were 72, 54 and 35 µg/m3 respectively and for PM2.5 22, 17 and 18 µg/m3 respectively. In order to determine the potential sources of particulate matter, analysis of the Teflon filters has been undertaken. The physical characteristics of the particles have been identified using Scanning Electron Microscopy. The relationships between personal exposure concentrations and the different microenvironments will be discussed.
