Description of key information
Six acute experimental studies based on international guidelines are available to assess the aquatic toxicity of the registered substance.
Among all data available, toxic effects were observed on two aquatic trophic levels (fish and algae). The most sensitive species is the fish Cyprinus carpio, with a 96h-LC50 value measured at 2.9 mg/L. For the algae Pseudokirchneriella subcapitata, a slight concentration-response relationship was observed in the study on the growth rate inhibition but not sufficient to determine an ErCx value after 72 hours of exposure. The 72h-ErC10 and 72h-ErC50 values were determined above 4.15 mg/L, the highest attainable test substance concentration under the test conditions.
For the aquatic invertebrates Daphnia magna, no significant acute effects were observed up to and including the highest attainable test substance concentration (saturation), measured at 6.04 mg/L under the test conditions.
In addition, no significant effect of the registered substance was observed on the respiration of activated sewage sludge up to and including a nominal concentration of 100 mg/L.
Additional information
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.
