Additional information
A study was performed to assess the acute toxicity of test substance to Daphnia magna under static conditions at a temperature of 20 ± 1 °C. The study was conducted in accordance with EU Method C.2.
Daphnids were exposed to a limit test concentration of 100 mg/L of test substance dissolved in water. Analysis was performed for the test concentration plus a control at the test start and after 48 h of exposure.At the end of the test one replicate of each test concentration was sampled.
Observations were made on the immobilisation rate, after 24 and 48 h of exposure. The EC50 values obtained were > 100 mg/L for 24 and 48 h exposure period. The values obtained were based on the nominal concentrations of test substance. The mean measured concentration of the test material was 99 % of the nominal value.
The 48 h EC50 value of the test substance (nominal) was determined to be > 100 mg/L(Brown D, 1991).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
