Abstract
Concentrations of 3 pesticides, azinphos methyl, parathion [parathion-methyl] and penconazole in soil, runoff and rain, were measured in 2 experimental areas in Italy, to assess the behaviour of these chemicals and to provide an experimental validation of a predictive model for surface water contamination. Soil loads of azinphos methyl just after the treatment resulted in 23-26% of the applied dose. Significant concentrations were measured in runoff water, related to loads and physiochemical properties of the chemicals. High values were observed in rain water. Runoff water concentrations and treatment loads validated the SoilFug model showing good correspondence between measured and predicted values.
