Most concentrations of pesticides studied were below detection limits in the coastal zone of the Netherlands in 1991, except 4,4'-DDT, B-HCH, DNOC, dinoseb, dinoterb, metoxuron, chlorotoluron, isoproturon, diuron and methobromuron.

Observed (fieldwork) and estimated (model) concentrations were compared with guidelines and risk levels. From the 14 pesticides investigated in the model stud
