Description of key information
The test item is with high probability not acutely harmful to aquatic algae. No toxic effects occur within the range of solubility.
Key value for chemical safety assessment
Additional information
The effect of the read-across substance (CAS 7023-61-2) on the growth of Pseudokirchnerella subcapitata was investigated in a study following GLP and OECD guideline 201. Due to the low solubility of the read-across substance a water accommodated fraction has been tested. The algae were exposed for 72 hours to the test substance. Based on the algal growth rate an EC50>100 mg/l was determined (BASF SE, 2007).
The read-across justification is attached in chapter 13.
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.
