- Executive summary:
A study was conducted to determine the short-term toxicity of the substance to Daphnia magna according to OECD Guideline 202, in compliance with GLP. Four groups of 5 Daphnia magna each were exposed to a concentration of 100 mg/L for 48 h. Total organic carbon (TOC) concentrations were measured with a TOC analyser and the test substance was considered stable over the duration of the study. No immobilised daphnids were reported in the control and test groups. Under the study conditions, the 48 h EC50 of the substance for Daphnia magna was determined to be >100 mg/L (nominal) and > 97 mg a.i./L (mean measured) (Brown, 1987).
