Conclusion on classification
There is a harmonised EU classification for acute aquatic toxicity category 1 (M factor = 1) for the substance under EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008. Short-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and algae) and for fresh- and saltwater species.The lowest acute effect values for fish (Oncorhynchus mykiss), aquatic invertebrates (Mysidopsis bahia) and algae (Raphidocelis subcapitata) are >100 mg/L, 20 mg/ L and 0.39 mg/L, respectively. There are also studies on aquatic plants (Lemna Gibba) with ErC50 of 0.28 μg/L, so the substance is classified as Aquatic Acute 1 (H400), with a M-factor of 1000 included in the self-classification.
There is a harmonised EU classification for chronic aquatic toxicity category 1 (M factor = 1) for the substance under EU CLP. 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 (Cyprinodon variegatus), invertebrates (Daphnia magna) and algae (Raphidocelis subcapitata) are 10 mg/L, 10 mg/L and 0.033 mg/L, respectively. Since the lowest NOEC falls in the concentration range from 0.01 < lowest value < 0.1 mg/L and as the substance is not readily biodegradable, the substance needs to be classified as Aquatic Chronic 1 (H410) in accordance with EU CLP. The study on aquatic plants (Lemna Gibba) resulted in a NOEC of 0.080 μg/L, giving M-factor of 1000 which is included in the self-classification.
In conclusion, the substance is classified as Aquatic Acute 1 (H400) and Aquatic Chronic 1 (H410), with an M-factor of 1000 for both acute and chronic hazards, 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).
