    Criteria for Evaluation of Smog Forecast Systems (2000)
    Springer
    Environmental monitoring and assessment 60 (2000), S. 1-14 
    Details
    ISSN: 1573-2959
    Keywords: air pollution modelling ; forecast ; model evaluation ; ozone

    Notes: Abstract Forecasts of air quality provide information to the general public during periods with high levels of air pollution. Criteria for testing the validity and reliability of forecast systems are discussed. As the objectives of a forecast may widely differ (providing information to the public or triggering short-term emission reduction measures) there is not a single evaluation procedure. It is recommended to use a set of performance indicators. The strong year-to-year variability in occurrence of smog episodes makes it necessarily to use several years of data in the evaluation.

    Atmospheric Volatile Organic Compound Monitoring. Ozone Induced Artefact Formation (2000)
    Springer
    Environmental monitoring and assessment 65 (2000), S. 89-97

    Notes: Abstract Assessment of population exposure to VOC in ambient atmospheres is receiving heightened interest as the adverse health effects of chronic exposure to certain of these compounds are identified. Active (pumped) and passive samplers are the most commonly used devices for this type of monitoring. It has been shown, however, that these devices, along with all other preconcentration techniques, are susceptible to ozone interference. It is demonstrated that this interference occurs even at low ozone concentrations and that it may result in the under-estimation of population exposure. A convenient and effective ozone scrubbing method is identified and successfully applied and validated for both active and passive samplers for a range of VOC.

    Notes: Abstract A study to evaluate the effects of ethylene diurea (EDU) as a protective antiozonant for beans (Phaseolus vulgaris) submitted to different ambient ozone concentrations was performed in three stations of the rural Network for Air Quality Monitoring (Catalonia, NE Spain). The highest ozone concentrations were accompanied by significant reductions in fruit yield, number of fruits and shoot biomass. These reductions were lower in plants treated with EDU. The results showed toxic ozone effects on sensitive species such as beans and a protective antiozonant effect of EDU. The intensity of the EDU protective effect differed among the different stations characterised by different meteorological conditions and O3 concentrations.

    Notes: Abstract The stress by air pollution at the systematicPan-European 16 × 16 km2 forest (crown) condition monitoring network, is discussed by comparingsite-specific estimates of critical and presentconcentration and deposition levels for S and Ncompounds and ozone. Results indicate that theexceedance of critical levels, related to directabove-ground impacts, decrease going from O3 〉SO2 〉 N compounds. Critical N loads related toeffects on the forest understorey are exceeded atapproximately 25% of the plots, located mainly inWestern and Central Europe. Critical N loads relatedto effects on trees are hardly ever exceeded, but mostlikely, this is an under estimate. Critical aciddeposition levels are exceeded at approximately 30%of the plots with a low base saturation, where acidinputs may release toxic Al. This is especially thecase in Central and Eastern Europe, where presentloads are high and in boreal forest in SouthernScandinavia where critical loads are low. Although theuncertainties in the calculated exceedances is large,the spatial pattern, which is most important for acorrelative study, seems reliable, implying that thecritical load concept is suitable for regional risk assessments.

    Effects of environmental stress on forest crown condition in Europe. Part II: Estimation of stress induced by meteorology and air pollutants (2000)

    Notes: Abstract In order to assess the relationship betweenenvironmental stress and crown condition of foresttrees monitored since 1986 in Europe, estimates ofstress factors, including temperature stress, droughtstress and air pollution stress, were derived with thebest data, methods and models currently available.This paper presents information on the methods used toderive such stress factors, and on the overall ranges,the temporal trends, the spatial distribution and thereliability of the calculated stress factors. Thetemperature stress indices did not show much temporalvariation between 1985 to 1995. As expected spatialpatterns were north-south orientated, going fromcolder northern regions to warmer southern regions.The calculated relative transpiration showed a morecomplex pattern, coinciding to a large extend withpatterns of rainfall and temperature. Potential aciddeposition decreased between 1986 and 1992, butremained fairly constant after 1992. The strongdecrease was mainly the result of the decrease inSOx deposition, and to a small decrease inNOy deposition. Highest levels of the S and Ndeposition were calculated in Central and WesternEurope. Base cation deposition was largest in coastalareas and in southern Europe. This is mainly due tosoil dust, Sahara dust and sea salt. Base cationdeposition can compensate almost entirely for thepotential inputs in the south of Europe, whereas incentral Europe it equalled about 25% of thepotential acid input. A comparison between sitespecific modelled deposition and deposition derivedfrom throughfall data showed that the total aciddeposition is usually overestimated by the model,whereas the total nitrogen deposition isunderestimated, especially at plots with high nitrogenloads. There is, however, a significant correlationbetween measured and modelled data for all S and Ndeposition, thus allowing their use in a statistical analyses.

    Identification of New Drinking Water Disinfection by - Products from Ozone, Chlorine Dioxide, Chloramine, and Chlorine (2000)

    Notes: Abstract Many drinking water treatment plants are currently using alternative disinfectants to treat drinking water, with ozone, chlorine dioxide, and chloramine being the most popular. However, compared to chlorine, which has been much more widely studied, there is little information about the disinfection by-products (DBPs) that these alternative disinfectants produce. Thus, it is not known if the DBPs from alternative disinfectants are safer or more hazardous than those formed by chlorine. To answer this question, we have set out to comprehensively identify DBPs formed by these alternative disinfectants, as well as by chlorine. The results presented here represent a compilation of the last 8 years of our research in identifying new DBPs from ozone, chlorine dioxide, chloramine, and chlorine. We also include results from recent studies of Israel drinking water disinfected with both chlorine dioxide and chloramine. Over 200 DBPs were identified, many of which have never been reported. In comparing by-products formed by the different disinfectants, ozone, chlorine dioxide, and chloramine formed fewer halogenated DBPs than chlorine.

    Towards a Science-Based Integrated Ozone-Fine Particle Control Strategy (2000)
    Springer
    Water, air & soil pollution 123 (2000), S. 195-201 
    Details
    ISSN: 1573-2932
    Keywords: air quality standards ; control strategies ; fine particles ; ozone
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Epidemiology studies relating health effects to ambient levels of ozone and fine particles have led to the modification of standards in the United States for these pollutants (substitution of an 8-h standard for ozone at 80 ppbv, and addition of 24-h and annual standards for fine particles). The interrelationships of these pollutants in the atmosphere suggest the need for an integrated, science-based strategy for their control. Secondary ozone formation has been controlled through emission controls on VOC and NOx precursors. Fine particles are secondary products largely resulting from the oxidation of precursors (SO2, NOx, and VOCs). The key intermediates in both types of secondary process are free radical species and the photochemically labile compounds that produce them in the atmosphere. However, due to the complex and nonlinear nature of the processes, reductions in precursors may lead to unexpected changes in ozone and fine particle formation rates. For example, reduction in NOx emissions may reduce ozone and nitric acid levels, but lead also to increased rates of sulfate formation in clouds and increased ammonia availability for neutralization of acidic sulfate aerosols. Reductions of SO2 may reduce aerosol sulfate levels in the summer, but have no effect in other seasons. Reductions in VOCs may reduce ozone levels in urban core areas, but not elsewhere. An integrated, regionally and seasonally specific, emission reduction strategy is needed to cost-effectively reduce both ozone and fine particle levels.

    A Three-Dimensional Model Study of the Impact of AVOC and BVOC Emissions on Ozone in an Urban Area of the Eastern Spain (2000)
    Springer

    ISSN: 1573-2959
    Keywords: Three-dimensional model ; anthropogenic emissions ; BVOC ; photochemistry ; ozone
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract This study concentrated on the effects of Biogenic Volatile Organic Compounds (BVOC) emissions on ozone (O3) in an area of the Eastern Spain on June 12, 1997, a day characterised by sea breeze. Simulation of meteorology was performed with the three-dimensional model ADREA-I. Comparisons of the model results with observations have revealed overall a good agreement in temperature and wind velocity. Two runs were performed with UAM-IV for the photochemical calculations. The first simulated the effects of the anthropogenic emissions only (run A) and the second the combined effects of anthropogenic and biogenic emissions, (run B). Comparisons of the model O3 concentrations with measurements showed a general agreement with the experimental data. Discrepancies between the calculated results and the observations during the early morning hours could be attributed to inaccuracies in nitrogen oxides (NOx) from the anthropogenic emissions inventory. Comparisons between runs A and B yielded differences up to 30% in the morning, over inland areas. It was deduced that the inclusion of BVOC in total emissions could result in an increase or decrease of tropospheric O3, depending on the available amounts of anthropogenic emissions.

    Urban Air Pollution Monitoring with DOAS Considering the Local Meteorological Situation (2000)
    Springer
    Environmental monitoring and assessment 65 (2000), S. 119-127 
    Details
    ISSN: 1573-2959
    Keywords: DOAS ; Differential Optical Absorption Spectroscopy ; urban air quality ; monitoring ; vertical distribution ; ozone
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract The concentrations of ozone, NO2 and SO2, measured with a DOAS system 70 m above ground level in the city of Graz were compared with data from conventional ground stations. The dependence of vertical trace-gas distributions on stability categories and time of the day or year was investigated. Concerning the maximum ozone concentrations in summer, the DOAS data are representative for the ground-level situation. In average, the concentrations 70 m above ground are more than twice the ground-level concentrations. It has been shown that beside the reaction with NO, dry deposition is an important sink for ozone near the surface. The DOAS NO2-concentrations are representative for ground-level conditions in summer, except for the morning maximum of NO2. In winter the DOAS NO2-concentrations amount for 73% of the ground level values in average. Concerning the slow reacting trace gas SO2, the DOAS data are always representative for the ground-level conditions.

    Grey Box and Component Models to Forecast Ozone Episodes: A Comparison Study (2000)

    Notes: Abstract For the purpose of short-term forecasting of high ozone concentration episodes stochastic models have been suggested and developed in the literature. The present paper compares the quality of forecasts produced by a grey box and a component time-series model. The summer ozone patterns for three European urban areas (two continental and one mediterranean) are processed. By means of forecast performance indices according to EC and WHO guidelines, the following features of the models could be found: The grey box model is highly adaptive and produces forecasts with low error variance that increases with the time horizon of forecast. The component model is more 'stiff' that results in a higher forecast-error variance and poorer adaption in detail. The forecast horizon, however, could be enlarged with this model. The accuracy of predicting threshold exceedance is similar for both models. This can be understood from the assumption of a cyclical time development of ozone that was made for both models.
