Description of key information
The 21–d chronic toxicity of test substance to Daphnia magna was studied under semi-static conditions. Daphnids were exposed to control, and test chemical at the nominal 1.8, 5.6, 18, 56, and 180 mg/L loading rates for 21 d. Immobilization and reproductive effects were observed daily.
Given that toxicity cannot be attributed to a single to a single component or mixture of components but to the test material as a whole, the results were based on nominal loading rates only.
The 21 -d EL50 (immobilisation) was 100 mg/L. The 21 -d EL50 (reproduction) was 89 mg/L.The 21 -d NOELR based on immobilization and reproduction was 56 mg/L
