Invertebrate and microbial communities in contaminated river sediments
The river sediments of Ardières and Tillet are both polluted with complex substance mixtures. The effect of the contamination with PCB on the oligochaete communities was clearly visible. The effect of the contamination on microbial communities was harder to assess because microbes are influenced by a multitude of environmental factors.

Assessment of sediment quality in artificial canals in Valais
Ecotoxicological bioassays and the assessment of invertebrate benthic communities complement physico-chemical analyses when assessing sediment quality. The sediment quality in three artificial channels in the Valais was severely affected.

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.
