Les cours d'eau suisses contiennent tout un cocktail de pesticides. Sur plus de 300 substances autorisées et détectables, plus de cent ont été relevées dans des échantillons d'eau lors d'un screening minutieux. Chaque échantillon contenait en moyenne 40 substances différentes. Dans 78% des échantillons, la concentration cumulée des pesticides dépassait 1μg/l. L'exigence numérique de l'Ordonnance sur la protection des eaux a été dépassée pour 31 substances. Une pollution des organismes aquatiques - notamment par des produits phytosanitaires - ne peut être exclue.
