Additional information


Two short term toxicity tests on fish are available:


The short-term toxicity to freshwater fish was determined in a study according to OECD TG 203 and in compliance with GLP criteria. In this study, groups of 7 zebra fish (D. rerio) the 96-h LL50 was calculated as geometric mean of the LL0 and LL100 to be 17.7 mg/L. In this study all OECD validity criteria were met.

In a second study which is used for PNEC derivation, Chinses rare minnow (Gobiocypris rarus) were exposed for 96 h towards the registered test substance according to OECD 203 (GLP study). The LC50 was determined to be 5.73 mg/L. In this study all OECD validity criteria were met.
