Additional information
A study was performed to assess the acute toxicity of test substance to Daphnia magna STRAUS under static conditions. 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.
Observations were made on the swimming ability and immobilisation rate, after 24 and 48 h of exposure.
The results are expressed in terms of nominal concentrations (at 24h), and in terms of mean measured concentrations (at 48h). Measured concentrations correspond to 81.8 and 85.9 % of nominal values at 0 and 48 h, respectively. The hardness of the dilution water used was 18.1 °dH (=323.1 mg/L CaCO3).
The 48 h EC0 value of the test substance (including inorganic components) was determined to be≥83.9 mg/L(Dr. Bruns, 2002).
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
