Description of key information

The 96-h LC50 value is >120 mg/L in freshwater fish (Danio rerio).

Key value for chemical safety assessment

Additional information

The short-term toxicity to freshwater fish was determined in a limit test according to OECD TG 203 and in compliance with GLP criteria. In this study, groups of 7 zebrafish (Danio rerio) were exposed to nominal test concentrations of 0 (control) and 120 mg/L based on active ingredient (corresponding to 863 mg/L test material) for 96 hours under static conditions. The nominal test concentration was analytically verified at the start and end of exposure and remained within ±20% of nominal. Therefore, the effect value is expressed as nominal. Fish mortality and general symptoms of toxicity were recorded after 24, 48, 72 and 96 hours exposure. In this study the OECD validity criteria are met. No mortality or general symptoms of mortality was observed during the test. Based on these findings the 96-h LC50 value was determined at >120 mg/L.
