Abstract
The Dutch aquatic environment was monitored from Sept. 1969-Dec., 1975 for organochlorine pesticides and their metabolites, cholinesterase inhibitors and aromatic amines. The 1492 samples analyzed included surface water, rainwater, groundwater and drinking water. The highest concentrations of the fungicide hexachlorobenzene and .alpha.- and .beta.-benzene hexachloride were in the Rhine River and its tributaries. Concentrations of the compounds in the Dutch part of the Rhine River decreased downstream. Other organochlorine pesticides and their metabolites, heptachlor, heptachlor epoxide, aldrin, dieldrin, endrin .alpha.- and .beta.-endosulfan and .SIGMA.DDT were detected occasionally, but only in low concentrations. Cholinesterase inhibitors and aromatic amines were always present in the Rhine River and its tributaries.
