Leaching of the organophosphorus nematicide fosthiazate 总被引:1,自引:0,他引:1

Fosthiazate is an organophosphorus nematicide which was recently included in Annex I of the Directive 91/414/EEC under the clause that it should be used with special care in soils vulnerable to leaching. Thus, the leaching of fosthiazate was investigated in columns packed with three different soils which represented situations of high (site 2), intermediate (site 1) and low (site 3) leaching potential. The recommended dose of fosthiazate was applied at the surface of the soil columns and fosthiazate fate and transport was investigated for the next two months. Fosthiazate concentrations in the leachate collected from the bottom of the columns packed with soil from site 2 exceeded 0.1 microgl(-1) in most cases. This soil was characterized as acidic, indicating longer fosthiazate persistence, with low organic matter content, indicating weak adsorption, thus representing a situation vulnerable to leaching. In contrast, the lowest concentrations of fosthiazate in the leachate were evident in the columns packed with soil from site 3. This soil was characterized as alkaline, indicating faster degradation, with higher organic matter content, indicating stronger adsorption, thus representing a situation not favoring leaching of fosthiazate. The highest concentration of fosthiazate in the leachate from the columns packed with soil from site 2 was 3.44 microgl(-1) compared to 1.17 and 0.16 microgl(-1), which were the corresponding maximum values measured in columns packed with soil from sites 1 and 3, respectively. The results of the current study further suggest that fosthiazate is mobile in soil and can leach under conducive soil conditions like acidic soils with low organic matter content. 相似文献

Goal, Scope and Background This paper describes a statistical modelling approach, suggested as a policy tool in the Athens area for the assessment of
the emissions reduction level required to meet the air quality standards for two criteria air pollutants, namely CO and NO2.
Methods. More than ten years of hourly CO and NOx-NO2 concentration data measured by the monitoring network of the Hellenic
Ministry for the Environment, Physical Planning and Public Works were analyzed and the original dataset has been reduced using
a data evaluation procedure.
Results and Discussion Seasonal pollutant concentration trends suggested that the reduction of CO and NOx concentrations observed in the beginning
of the '90s is almost entirely attributed to the increase of the catalyst-equipped cars during this period. The numerical
parameters of an empirical model relating EU standard exceedances with mean annual concentrations were defined and the model
was validated using datasets from years that were not used for the estimation of these parameters. This model was used in
conjunction with a roll-back equation as a policy tool for the assessment of the effect of different CO and NOx emissions
reduction scenarios on air quality standard compliance for CO and NO2. Results predicted with this empirical modelling approach
were assessed with monitored data averaged over a 3-year period, giving satisfactory results.
Conclusion A methodology suggested for assessing the effects of different emissions reduction scenarios on air quality standard attainment
was successfully applied for CO and NO2 in the Athens area.
Recommendation and Perspective The proposed methodology can provide a useful tool for the evaluation of policies already in progress as well as the development
of future policies for emissions reduction in urban areas with similar characteristics, aiming at air quality standard compliance
on a timely manner. Such a methodology could be applied in other urban areas of Greece characterized by dense traffic, therefore
assisting the development of national policies in relation to air pollutants for which standard exceedances occur. 相似文献
