Results of the Use of Two Environmental Models for Pesticides Ranking by Hazard
Modelling investigation have been performed for determination of estimated concentrations of pesticides in water and for hazard categories. Predicted environmental concentration (PEC) and hazard categories for aquatic life as well as estimated human daily intake were evaluated by USES model for 275 pesticides and by HESP 2.10b software for 99 of them.
Comparison of hazard classification in line with criteria proposed by J.Linders showed that hazard categories obtained by HESP are higher than by USES. The results demonstrated that both models might be used for ranging pesticides by hazard. The appropriate use and limitations of the models should be emphasised.
