Description of key information
Additional information
Short term measured data for the registered substance (3 -chloroproyl)diethoxymethylsilane (13501 -76 -3),was available for fish, invertebrates and algae
A 96-hour LC50 value of 574 mg/L was determined for mortality of Brachydanio rerio (EU method C.1 acute toxicity to fish, Hüls AG, 1995b). A 48-h EC50 value of 295 mg/L and a 48-h NOEC value of 106 mg/L have been determined for the effects on mobility of Daphnia magna (EU method C.2 acute toxicity for Daphnia magna, Hüls AG, 1994b) and 72-hour EC50 value of 437 mg/L and NOEC of approximately 57 mg/L have been determined for the effects on growth rate of Scenedesmus subspicatus (EU Method C.3 Algal Inhibition test, Hüls AG, 1994c). The results of each of these studies are interpreted with reference to nominal concentrations of the test substance. However it is likely that the test organisms were also exposed to the hydrolysis products of the 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.
