Use of bioassays for the assessment of industrial wastewaters

Micropollutants can enter the environment from a variety of sources. In addition to substance inputs from agriculture or households, discharges from industry and commerce into water bodies play an important role. Thus it can be assumed that up to 20% of relevant substance inputs into water bodies originate from industry (see the report of the Federal Council on "Measures at the source to reduce micropollutants in water bodies" of June 16, 2017). So far, little is known about the composition and impact of industrial and commercial wastewater in Switzerland.

In combination with chemical analyses, bioassays are an important complement to toxicity detection in industrial wastewater. Bioassays can indicate both mixture toxicity and the effects of micropollutants that have not been specifically investigated chemically and can reveal ecologically relevant effects of toxic wastewater on various organisms (e.g. algal, insect or fish toxicity).

Our project on behalf of the Federal Office for the Environment: "Overview study on the use of bioassays for the assessment of industrial wastewater and proposal of an investigation concept" aims to systematically collect and analyze national and international knowledge on the application of bioassays for industrial wastewater investigation. The knowledge gained will be used to develop an application-oriented concept to investigate industrial wastewater using bioassays.
