Additional information
The acute toxicity of the test item to rainbow trout (Oncorhynchus mykiss) was determined in a 96 -hour static test, according to the OECD Guideline 203 (1992) and the method C.1 of the Directive 92/69/EEC. Seven fish were exposed to a nominal concentration range from 7.5 to 120 mg/l.
The analytic results showed that the substance was stable under test conditions for at least 96 hours. The LC50 (96h) was found to be > 120 mg/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.
