English Abstract Based on the assignment described in the Multi-year
crop protection plan (1991) in this report the question is discussed whether
a detailed procedure could be described for the study of the transformation
of pesticides in the groundwater zone. First, in an analysis of the
question the quantitative and qualitative prerequisites specified for this
transformation have been clarified. Thereafter it is discussed whether
sufficient knowledge and information was available to prepare this
procedure. Therefore, a literature review of known studies is described.
Based on this information it has been concluded that no detailed procedure
for this study could be described. Also it has been considered whether the
presently available information in the pesticide dossiers (on chemical
hydrolysis and transformation in the top soil) could be used to evaluate the
fate in the groundwater zone. Also this question was negatively answered.
Based on these discussions conclusions have been drawn, which have not
resulted in a detailed procedure for the study, but in guidelines for the
execution of the study. Finally, it is suggested in what way the evaluation
of methods and results of this type of studies might be organized in
future.
