Dynamic modelling of surface waters: impact of emission reduction-possibilities and limitations
Dynamic models provide an extension to critical loads by predicting the timescale of chemical recovery to emission reductions. They can also be used to determine the deposition levels required to…
Incorporating macropore flow into focus PEC models
Macropore flow can strongly influence leaching of pesticides in the unsaturated zone, but this process has until now played only a limited role in exposure assessments.
European exchange of air quality monitoring meta information in 2001. ETC/ACC technical paper 2003-1
Current air quality legislation of the European Union, Council Decision (97/101/EC), requires the Commission to prepares a technical report on a yearly basis combining the meta information and air…
Development of an environmental indicator which can be used on national and regional scales for evaluating pesticide emissions in The Netherlands
As part of the new governmental program on pesticides the Dutch ministry of Agriculture, Nature Management & Fisheries and the ministry of Housing, Spatial Planning & the Environment have jointly…
Comparison of GeoPEARL with the single scenario approach in pesticide registration
Several countries use one or a few scenarios to evaluate the leaching of pesticides. This, however, can be too strict for some substances while being too lenient for others, because of the wide ranges…
Nationwide assessments of non-point source pollution with field-scale developed models: the pesticide case
The use of nationwide models of non-point source pollutants in soils is now common practice. Most of these models have originally been developed at the field-scale. An integrated approach (a ‘research…
Methodological approach for evaluating first tier PEC groundwater scenarios supporting the prediction of environmental concentrations of pesticides at the European scale
Within the framework of the harmonised registration of plant protection products (PPPs) at the EU-scale, environmental fate models are nowadays combined with a series of scenarios to predict the…
Modelling and Mapping of Critical Thresholds in Europe
This report informs parties under the Convention on Long-range Transboundary Air Pollution (CLRTAP) and its network of National Focal Centres on the recent update of the European critical loads…
Are we sure? Some thoughts about uncertainty treatment in integrated assessment
‘Are we sure?’ ‘Are we right?’ ‘Do we feel confident?’ These questions summarise the feeling of uncertainty that is always nagging at our conscience whenever a policy decision is going to be based on…
