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.

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.
