|Abstract||The acute fish toxicity (AFT, OECD TG 203) is required to provide information on the acute
toxicity of chemicals for environmental hazards and risk assessment. It is conducted as part
of the registration of (industrial) chemicals under European regulations as well as other
regulations. To reduce the number of tests on animals, the REACH Regulation promotes
alternative methods for the hazard assessment of substances. For example, testing
according to OECD Technical Guideline 236 (fish embryo acute toxicity test (FET)) has been
suggested as one of the alternative methods to toxicity testing in adult fish.
The aim of this study was to assess the capacity of the FET test in predicting acute fish toxicity and to define the applicability domain of the FET test for regulatory purposes. The existing fish embryo data (acute - 96h LC50) were compared to data on adult fish toxicity (acute - 96h LC50) and the limits of applicability investigated by analysis of the relation of the results with respect to physicochemical parameters, structural domains, excess toxicities (i.e. the ratio of predicted baseline toxicity LC50 versus observed acute LC50, also called toxic ratio).
