Additional information
The acute toxicity of the test substance to Daphnia magna was determined in a 48-hour static test according to the OECD Guideline 202.
The nominal test concentrations were 0.46, 1.0, 2.1, 4.6, 10.0 mg test substance/l, and in parallel a control.
The 48-hour EC 50 was calculated to be 2.13 mg test substance/l with 95 % confidence limits from 1.75 to 2.60 mg/l. The 48-hour EC and also the 48- hour NOEC was 1.0 mg/l, since no immobilization and no other signs of intoxication were observed at the test animals up to and including this test concentration. The 48-hour EC100 amounted to 10.0 mg test substance/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.
