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 (Cyprinodon variegatus), aquatic invertebrates (Mysidopsis bahia) and algae (Navicula pelliculosa) are 5.1 mg/L, 1.7 mg/L and 0.0042 mg/L, respectively. As the lowest value for algae is below 0.01 mg/L and above 0.001 mg/L, the substance needs to be classified as Aquatic Acute 1 (H400), with an M-factor of 100, in accordance with 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 fresh- and saltwater species. The lowest chronic effect values for fish (Oncorhynchus mykiss), invertebrates (Americamysis bahia) and algae (Navicula pelliculosa) are 0.25 mg/L, 0.11 mg/L and 0.000962 mg/L, respectively. Regarding the adequate chronic aquatic toxicity data (0.0001 mg/L < lowest value ≤ 0.001 mg/L) and the substance being not readily biodegradable, the substance needs to be classified as Aquatic Chronic 1 (H410) with an M-factor 100, 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.
