Additional information
In the only available (and reliable) study the acute toxicity of the test substance to Daphnia magna was investigated according to OECD test guideline 202 under GLP. In a 48h static test, five test concentrations (10 / 18 / 32 / 56 / 100 mg/L) were tested. Using a validated photometric method, agreement of nominal and measured concentrations was confirmed. All validity criteria were fulfilled. Based on mobility, the EC50 (48h) was determined to be 23 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).
