RIVM Report 679101023
This study compiles environmental concentrations of pesticides. Pesticide concentrations in surface water, groundwater, the atmosphere, soil and sediment are presented. The compilation is limited to measurements in the Netherlands. Information on these concentrations could be found for less than half of the 270 active ingredients, that are registered in the Netherlands. The current investigation shows that compounds in water quite often exceed the maximum accepted level for water (0.1 mug/l) used as source for drinking water. Some substances have been analysed, but they never exceeded the detection limits. Many substances have not been analysed at all. It was found that all but two compounds detected in groundwater exceeded this environmental quality objective.
