Fungicidal azoles cause concern

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

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.
