Description of key information

EC50 (48h) > 100 mg/L (nominal) for Daphnia magna (OECD 202)
measured concentrations after 96 h: 94.7 mg/L

Key value for chemical safety assessment

Additional information

A study on the short-term toxicity of acetic acid, chromium salt, basic to aquatic invertebrates is available (Muckle and Rudolf, 2008). The study was conducted according to GLP and OECD 202. Daphnids were exposed to the test item for 48 hours under static conditions. In the study no precipitation occurred and the correlation between nominal and measured concentration was good. No mortality and no behavioural abnormalities were observed. The EC50 (48 h) and the NOEC were determined to be >100 mg/L and 100 mg/L, respectively.
