For fish (Danio rerio) the acute toxicity expressed in terms of lethal loadings (LL0, 96 h) of HDI Uretdion was > 100 mg/l. The studies were conducted according to Directive 92/69/EEC, C1 (Bayer Industry Services, 2000).

HDI Uretdion was tested with respect to the acute toxicity towards invertebrates (Daphnia magna) according to Directive 92/69/EEC, C2. After 48 hours effective a concentration value (EC50, 48 h) of > 100 mg/l was obtained (Bayer Industry Services, 2005).

The toxicity of HDI Uretdion to algae (Desmodesmus subspicatus) was assessed performing a study according to the Directive 92/69/EEC, C.3. The nominal values showed 72 h-EL 50 values for the growth rate to be between > 50 mg/l and < 100 mg/l (BIS, 2000).
