Description of key information
Additional information
Experimental studies cover the toxicity to three different trophic levels (fish, aquatic invertebrates and algae). All studies were performed according to internationally accepted guidelines and the principles of GLP. Freshwater invertebrates turned out to be the most sensitive species with an EC50 (48 h) of 0.0068 mg/L followed by freshwater fish with a LC50 (96 h) of 2.8 mg/L and aquatic algae with an ErC50 (72 h) of 9.3 mg/L. Except for aquatic algae (NOErC (72 h): < 0.33 mg/L) no chronic toxicity data are available. The respiration inhibition of activated sludge was studied in one experimental study. It resulted in an EC50 (3 h) of 137.5 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.
