Ecotoxicity tests

 How are these tests performed?

The reference organisms are exposed to different concentrations of a product or dilutions of a certain water sample during a certain period of time. Depending on the reference organism, the effect is assessed at different levels (reproduction, growth rate, mortality, ...).

The results are processed into a dose-response curve that reflects the effect according to the dilution of the product or water sample. The concentration or dilution at which 50% of the test population experiences an effect, the so-called EC50 value, is derived from this. Based on this value, the toxicity of a product or water sample can be assessed.
