Description of key information
LC50 (96h) 35 mg/l, NOEC 25 mg/l and LC100 at 50 mg/l for Oncorhynchus mykiss (OECD 203), RL1
Key value for chemical safety assessment
Additional information
In an acute fish toxicity test according to OECD 203 and GLP, the 96 -h LC50 for Rainbow trout Oncorhynchus mykiss exposed to dichloromethyl(3,3,3-trifluoropropyl)silane is 35 mg/l, while no mortality (NOEC) was observed at 25 mg/l and 100% mortality was revealed at 50 mg/l (Fournier, 2012). Based on the expected rapid hydrolysis of the test substance into a mixture of monomeric and oligomeric products, the effects are contributed to the whole mixture and are presented based on nominal loading rates of parent test substance.
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.
