Description of key information
Three acute experimental studies are available to assess the aquatic toxicity of the registered substance, on aquatic invertebrates, fish and algae.
The 96 hr LC50 on Oncorhynchus mykiss according to OECD 203, was determined to be 4.2 mg/L (based on nominal concentrations, measured concentrations were >80% to nominal).
The 48 hr EC50 on Daphnia magna according to OECD 202 was determined to be 13 mg/L (based on nominal concentrations, measured concentrations were >80% to nominal).
The 72 hr EC50 on aquatic algae according to OECD 201 based on growth rate was reported to be 10 mg/L (based on nominal concentrations, measured concentrations were >80% to nominal).The 72h EC10 based on growth rate was reported to be 5.2 mg/L (based on nominal concentrations, measured concentrations were >80% to nominal).
Two QSAR are available to assess the chronic aquatic toxicity of the registered substance on fish and on aquatic invertebrate
The fish 32/33d-NOEC was predicted to be 0.426 mg/L.
The daphnia 21-d NOEC was predicted to be 0.350 mg/L.
The substance was not acutely toxic to microorganisms when tested according to OECD 209. The 3 hr EC50 for activated sludge respiration inhibition was reported to be 190 mg/L (nominal).
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.
