Additional information
Conclusion on classification
Short-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and algae). The lowest acute effect values for fish (Oncorhynchus mykiss), aquatic invertebrates (Daphnia magna) and algae (Pseudokirchneriella subcapitata) are >100 mg/L, 87.0 mg/L and 23.8 mg/L, respectively. The substance does not need to be classified for acute aquatic hazard.
Long-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and algae). The lowest chronic effect values for fish (Oncorhynchus mykiss), aquatic invertebrates (Daphnia magna) and algae (Pseudokirchneriella subcapitata) are 11.7 mg/L, 0.0251 mg/L and 6.28 mg/L, respectively. Regarding the adequate chronic aquatic toxicity data (lowest value ≤ 0.1) and the substance being not readily biodegradable, the substance needs to be classified as Aquatic Chronic 1 (H410) with an M-factor of 1.
In conclusion, the substance is classified as Aquatic Chronic 1 (H410), with an M-factor of 1, as in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
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.
