Strategy for assessing sediment quality in Switzerland

Strategy for assessing sediment quality in Switzerland

After 6 years, the assessment concept for sediment quality in Switzerland is in the home straight. In addition to a harmonised method for sampling and sample preparation, a list of substances for regular sediment monitoring has been developed, as well as sediment quality criteria and an evaluation system.

Biomonitoring for plant production products in Switzerland

Biomonitoring for plant production products in Switzerland

A monitoring concept for residues in Swiss agricultural soils is currently being developed as part of the action plan for the reduction of risks and sustainable use of plant protection products. The most important steps are the development of ecotoxicological guidance values for soils and the selection of suitable biological indicators.

Ecotoxicological effects of  polyacrylamides and polyacrylates in agriculture

Ecotoxicological effects of polyacrylamides and polyacrylates in agriculture

Polyacrylamides and polyacrylates can be used as soil conditioners. But since most chemical regulations do not apply to polymers, little is known about their ecotoxicological effects. A report summarises the current state of knowledge.

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.
