Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
3.1 mg/L

Additional information

Four reliable studies are available. In the key study the acute immobilisation (EC50) of the substance to Daphnia magna was determined according to OECD TG 202 and EC method C.2 under static conditions over a duration of 48 h [Noack M (2001)]. Daphnia magna were exposed to the substance at nominal concentrations of 0, 1.5, 3, 6, 12 and 24 mg AO/L. The 48 h EC50 value, based on nominal test concentrations, was 3.1 mg AO/L
