English Abstract
The "catch-up operation on old pesticides" project has resulted in a summary and RIVM conclusion of the environmental aspects of 152 pesticides which were already marketed in the Netherlands before 1975. The RIVM conclusion was subsequently rewritten to form an environmental synopsis. The present report describes the procedure followed and the results obtained in the evaluation of the environmental effects of these chemicals. Pesticides have been evaluated on the basis of the test results submitted with regard to their behaviour in soil and water, their effects on organisms present in the environment, such as birds, aquatic organisms (algae, crustaceans and fish), bees and earthworms, and their bioaccumulation potential. Behaviour in soil concerns the rate and route of conversion of a pesticide and its sorption to soil particles. The risks of leaching to the saturated soil layers and of accumulation in the plough layer one year after application of the chemical have been estimated using the Support Group M model developed for this purpose. Behaviour in water includes the rates of hydrolysis and photolysis, and especially the rate and route of conversion of a pesticide in water/sediment systems. Several proposals have been made for classification systems of environmental properties of pesticides in general. A classification system for persistence in particular is badly needed for the intercomparison of the pesticides. It appeared that various data necessary for the evaluation are still lacking for many pesticides. The report also makes proposals for developing several aspects of the evaluation, such as behaviour in air, risks to terrestrial organisms and risks of biomagnification.
