Description of key information
Additional information
Acute aquatic toxicity data are available for fish (Danio rerio, Leuciscus idus), aquatic invertebrates (Daphnia magna) and algae. The most sensitive species to the test item is algae with a 72-h ErC50 of 0.21 mg/L which is carried forward in the risk assessment of the substance. The related ErC10 (72 h) is 0.02 mg/L.
Information on the acute aquatic toxicity to fish and aquatic invertebrates was assessed in a weight-of-evidence approach:
The key value identified for the chemical safety assessment for fish is LC50 (96 h) = 3.14 mg/L.
The identified key value for aquatic invertebrates (Daphnia) is EC50 (48 h) = 0.3162 mg/L.
The EC50 (respiration inhibition) of activated sludge after 30 min is 59 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.
