Additional information
A guideline chronic study for aquatic invertebrates is available for the test substance. The key study is an OECD 211 test with Daphnia magna. The 21-d NOEC on reproduction was determined at 1000 mg/L (nominal, NITE, J-CHECK databank, 2002).
In addition, a single semi-static GLP-study conducted by Springborn Laboratories according to the EPA guideline 1002.0 from 1989 is available. In this study, the effects of the test substance on Ceriodaphnia dubia was studied over a time period of 7 days. The NOEC determined for mortality was 625mg/L (nominal, TSCAT, data published, OTS0516624-6, 1989). These results were not used for assessment, since the testing time of 7d was considerably shorter than in the other 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.
