An Ecotoxicological Approach to Evaluate the Environmental Quality of Inland Waters

Pesticides in surface waters: a comparison with regulatory acceptable concentrations (RACs) determined in the authorization process and consideration for regulation

BACKGROUND Chemical analysis of surface water conducted in European countries indicates that pesticides are often detected in surface waters. This asks regulatory authorities to consider these monitoring data while re-evaluating pesticide approval and setting appropriate risk mitigation measures. During the years 2005-2012, the cantons in Switzerland performed 345,000 pesticide measurements in ...
