Conclusion on classification
Short-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and algae) for fresh- and saltwater species. The lowest acute effect values for fish (Oncorhynchus mykiss), aquatic invertebrates (Crassostrea virginica) and algae (Scenedesmus subspicatus) are 19 mg/L, 2.6 mg/L and 0.077 mg/L, respectively. As the lowest value for algae is < 0.1 mg/L, the substance is classified as Category Acute 1 aquatic toxic with an M-factor of 10 according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
Long-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and algae) for freshwater species. The lowest chronic effect values for fish (Oncorhynchus mykiss), invertebrates (Daphnia magna) and algae (Scenedesmus subspicatus) were 0.305 mg/L, 0.023 mg/L and 0.021 mg/L, respectively. Regarding the adequate chronic aquatic toxicity data (0.01 mg/L < lowest value ≤ 0.1 mg/L) and the substance being not readily biodegradable, the substance needs to be classified as Aquatic Chronic 1 (H410) with an M-factor 1, 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.
