Description of key information

(48 hr) EC50 295 mg/L mobility Daphnia magna. Reliability 1

Key value for chemical safety assessment

Additional information

A 48-h EC50 value of 295 mg/L and a 48-h NOEC value of 106 mg/L have been determined for the effects of the test substance on mobility of Daphnia magna (EU method C.2 acute toxicity for Daphnia magna, Hüls AG, 1994b). The results are interpreted with reference to nominal concentrations of the test substance. However it is likely that the test organisms were primarily exposed to the hydrolysis products of the substance.
