Different approaches to assess water quality with bioassays
For the regulatory assessment of water quality with bioassays, uniform approaches are necessary. These may only use the EQS of the reference substance or include as many EQS of a substance class as possible.

Chironomids as PCB finders
Chironomid larvae were used to monitor the remediation of a site contaminated with PCB, both in the field under field conditions and in the laboratory under controlled conditions. Water quality improved significantly, but part of the contamination remained.

Soil organisms like it hot
The bait lamina test is a useful method to determine the soil quality in the field. The Ecotox Centre has examined the influence of soil moisture on the test results in more detail: This facilitates the interpretation of the method and brings the test one step closer to routine application.

Bioassays for the assessment of water quality
Within the Modular Stepwise Procedure a concept has been developed for the overall assessment of rivers that are contaminated with waste water using ecotoxicological bioassays. The concept represents a first step towards an integrative assessment of water quality.

Eawag supports introduction of effect-based environmental quality criteria
At the end of November, the Federal Council has sent the new risk-based required limits for biocides, plant protection products and other micro-pollutants within the Water Protection Ordinance in consultation. A new Eawag fact sheet shows why these values are meaningful and necessary.

Estrogens in surface waters - Screening and risk assessment for Europe
In the framework of an international project, European water samples were analysed for estrogens using various biological and chemical methods. Bioassays based on cell cultures were shown to be well suited to detect the substances that are to be monitored across Europe.
