Bioassays and biomarkers to assess water and sediment quality
The Ecotox Centre used numerous bioassays and biomarkers to investigate the water quality at 17 sites. The ecotoxicological risks were determined on the basis of the bioassays and compared with the risks determined on the basis of chemical measurements. Based on the results, the Centre proposes suitable methods for routine use.

Assessment of water quality with a bioassay battery
A comprehensive study on the assessment of water quality in Switzerland shows that chemical measurements and bioassays complement each other. While risks to fish were detected more sensitively with bioassays, chemical analysis was the more sensitive method for risks to invertebrates from pyrethroid insecticides. The Ecotox Centre proposes a bioassay battery for routine testing.

Assessment of sediment quality with a bioassay battery
The Ecotox Centre proposes a battery of three bioassays to determine the quality of sediments and to complement chemical analysis. The test with ostracods reacts particularly sensitively and is suitable as a screening method for biological effects.

Assessment of water quality with biomarkers in brown trout
Biomarkers detect effects of pollutants on wildlife early and sensitively and complement chemical measurements. Further studies on the natural variability of the method are needed.

Ecotox Centre gets to the bottom of the fish decline in the Suze
The fish population and the number of small animals in the Suze have declined sharply. In order to estimate the pollution of the Suze, the Ecotox Centre examines water and sediment using various bioassays.

Federal Council adopts revised Water Protection Ordinance
On 16 December 2022, the Federal Council approved the revised Water Protection Ordinance defining the criteria for when the authorisation of a pesticide must be reviewed. In this way, drinking water and surface waters will be better protected from pesticides.
