Description of key information
Daphnia magna were exposed to nominal chloroprene concentrations of 0 (control), 6.25, 12.5, 25, 50 and 100 mg/L for 48 hours under static conditions according to EU Method C.2 Acute toxicity for Daphnia (2008). Geometric mean measured concentrations were 2.51, 5.42, 11.17, 21.68 and 45.17 mg/L in the nominal 6.25, 12.5, 25, 50 and 100 mg/L treatments. Based on mean measured concentrations the 24 hour EC50value was calculated to be 15.32 mg/L and the 48 hour EC50value was 11.17 mg/L. The no-observed effect concentration (NOEC) was observed to be 5.42 mg/L.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
