Fungicidal azoles cause concern
In Switzerland, these substances are detected in most samples from water, sediment, soil and organisms. However, a lack of toxicity data for many azoles makes it difficult to assess the risk they pose.

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.

How do plant production products affect Swiss fish?
Pesticides detected in Swiss streams pose a risk to the fish living there. Harmful effects on the fish, particularly through sublethal and indirect effects, are possible in the measured concentrations.

Homing in on pyrethroids
The measurement of trace concentrations of pyrethroid and organophosphate insecticides – now possible thanks to a newly developed analytical method – shows that these compounds can pose a greater threat to aquatic organisms than all other pesticides.
