For the first time, a toxicity test with gill cells from fish, developed by EAWAG from Dübendorf, Switzerland, have been ISO-certified. The test serves to determine acute toxicity of water samples and chemicals to fish. This is a Milestone, because so far there was a lack of recognized alternatives to experiments with living fish.
The test is now available to anyone who wants to test acute fish toxicity of water samples or certain chemicals - from sewage plant operators to environmental agencies or chemical companies, said developer Dr. Kristin Schirmer in an interview on the subject.
