Pesticide fate models for evaluating groundwater contamination
The procedures used for assessing the potential movement of pesticides to groundwater in the EU registration process were studied. Two pesticide leaching models (MACRODB, PEARL) were parameterized, calibrated, and tested in lysimeter experiments. Six realistic standard scenarios, which collectively represent the agriculture in Russia, and appropriate data input files for these models were developed. Soil properties, weather data, and crop information were defined for all scenarios. MACRODB, PEARL, and standard scenarios were recommended for use in the national pesticide registration procedure.
