Description of key information
In an OECD 203 study in zebra fish, the 96-hour NOEC (highest concentration tested without observable toxic effects after the exposure period of 96 hours) was the loading rate of 10 mg/L. The 96-hour LOEC (lowest concentration tested with observable toxic effects) and the 96-hour LC0 of test substance to Zebra fish was the loading rate of 22 mg/L.
The 96-hour LC50 of the test substance was calculated to be at the loading rate of 42 mg/L with a 95% confidence interval of 32–57 mg/L. The 96-hour LC100 was the loading rate of 100 mg/L.
In an OECD 202 study in Daphnia magna the 24 hour EC50 value was 87 mg/L. The 24 hour EC0 was 22mg/L/ and the 24 hour EC100 was above the loading rate of 100 mg/L.
The 48 hour EC50 value was calculated to be 56 mg/L. The 48 hour EC0 and the 48 hour NOEC were 22 mg/L. The 48 hour EC 100 was above the loading rate of 100 mg/L.
In an OECD 201 study on the effect of the test substance on the growth of Scenedesmus subspicatus the EC50 value was determined to be greater than the 100 mg/L loading rate WAF. The LOEC was 100 mg/L and the NOEC was 32 mg/L.
In an OECD 209 study the effect of the test substance on the respiration of activated sewage sludge microorganisms gave a 3-hour NOEC (EC15) of at least 1000 mg/L.
Additional information
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.
