Description of key information
Additional information
Short term tests with species of 3 trophic levels are available. Algae turned out to be the most sensitive species revealing an EC50 (72h) of 32 mg/L. Short term effects of the substance towards fish and daphnia were found in the same range providing a LC50 (96h) of 70 mg/L and an EC50 (48h) of 86 mg/L, respectively.
In a short respiration test a 30 -min EC20 of 35 mg/L was determined. The results for a Pseudomonas putida test were 30 min EC10 of 57 mg/L.
Thus, the test substance is acutely harmful to aquatic organisms. Depending on local conditions and existing concentrations, disturbances in the biodegradation process of activated sludge are possible.
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.
