- 100 mg/L
Additional information
A static freshwater toxicity test was conducted (to OECD Guideline 202) to determine the acute toxicity of the water available fraction of the test substance to the water flea, Daphnia magna. A limit test was initiated with one concentration of test substance (100 mg wm/l loading rate, the maximum loading rate for this test substance)., which was applied to the dilution water and stirred to achieve a stable water available fraction (WAF). The criterion for effect was death or immobilization (i.e., no movement except for minor activity of appendages).
The 48 hour EC50 and NOEC were >100 mg wm/L (expressed as loading rate) based on the lack of mortality and sublethal effects observed at this test concentration. The 48-hour EC50 was incalculable because of the absence of mortality during the 48-hour test.
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.
