Description of key information

In an acute immobilization test with Daphnia magna (STRAUS), the effects of the Benzaldehyde were determined according to OECD 202. Based on this study, the 48-hour EC50 (immobilisation) value in daphnia is reported to be 19.7 mg/l.

This value is further supported by the Bringmann and Kuhn (1977) reported 24 -hour EC50 of 50 mg/l and the ECOSAR prediction of 16.2 mg/l.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
19.7 mg/L
