Different approaches to assess water quality with bioassays

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

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.
