Few estrogens in Europe's rivers
Studies with biotests have shown it: Most European watercourses do not contain estrogenic substances in critical concentrations. Switzerland has also participated in the huge monitoring project initiated by the Ecotox Centre. All Swiss samples were harmless.

Ecotoxicological effects of pesticides in stream sediments
Pesticides in sediments cause adverse effects on benthic organisms. This was shown by a monitoring study conducted by the Ecotox Centre and Eawag on five streams in agricultural areas. Crustaceans were particularly affected. Concentrations of several insecticides, including chlorpyrifos and the pyrethroid cypermethrin, exceeded effect thresholds, indicating impaired sediment quality.
