Conclusion on classification

Short-term aquatic toxicity data are available for three trophic levels (fish, mysid and algae), both for freshwater and marine environments. The acute effect values for freshwater (expressed in recalculated values for the pure test substance) for fish (P. promelas), invertebrates (Daphnia magna) and algae (N. pelliculosa) are 6.48 mg/L, 6.1 mg/L and 0.47 µg/L, respectively. The respective values for marine fish (Cyprinodon variegatus), invertebrates (Americamysis bahia) and algae (Skeletonema costatum) are >57 mg/L, 0.31 mg/L and 8.13 mg/L. Based on the information, the substance needs to be classified for acute aquatic hazard (H400, M-factor 1000) according to EU CLP Regulation (EC) No 1272/2008.

Long-term aquatic toxicity data are available for three trophic levels (fish, mysid and algae), for freshwater and marine environments. The chronic effect values (expressed in recalculated values for the pure test substance) for fish (P. promelas), invertebrates (Daphnia magna) and algae (N. pelliculosa) are 0.13 mg/L, 0.13 mg/L and 0.29 µg/L, respectively. The corresponding chronic effect values in the marine environment for fish (Cyprinodon variegatus), invertebrates (Americamysis bahia) and algae (Skeletonema costatum) are 2.55 mg/L, 0.0523 mg/L and 0.21 mg/L. Regarding the adequate chronic aquatic toxicity data (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 of 100.

In conclusion, the substance is classified as Aquatic Acute 1 (H400) (M-factor = 1000) and Aquatic Chronic 1 (H410) (M-factor = 100), as in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
