Additional information
The acute toxicity of the test substance to aquatic invertebrates was determined in a GLP-compliant test according to OECD 202 (CG, 1985).
In this study, Dapnia magna were exposed to nominal concentrations of 0, 10, 50, 100, 250, 500, 750 and 1000 mg/L of the test substance for 24 hours (static). Up to a test substance concentration of 100 mg/L no significant number of immobilized or dead test animals was observed. At the highest concentration tested immobilization reached 75%. Based on these results, the 24-h EC50 was determined at 959.5 mg/L.
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.
