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…
