Description of key information
Additional information
Available data on exotoxicity of the submission substance to aquatic organisms are restricted to sewage treatment plant microorganisms and freshwater fish. For both organism groups reliable studies were available, the study on fish (danio rerio) is corroborated by a database entry reporting a similar limit concentration. Consitently, neither with fish nor with activated sludge microorganisms could be any toxicity of the submission substance observed up to the highest tested concentration:
LC50 (Danio rerio, 48 and 96 h) > 473 mg/L (mean measured, corresponding to a nominal concentration of 500 mg/L);
EC50 (activated sludge mircroorganisms, 3h) > 730 mg/L (corresponding to 1000 mg/L test material containing 73% submission 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.
