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, aquatic invertebrates and algae are > 16 mg/L, 0.74 mg/L and 1.1 mg/L, respectively. As the lowest value is between 0.1 and 1 mg/L, the substance needs to be classified as Aquatic Acute 1 (H400), with an M-factor of 1, 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 two trophic levels (fish and invertebrates). The lowest chronic effect values for fish and invertebrates are 0.32 mg/L and 0.0032 mg/L, respectively. Regarding the adequate chronic aquatic toxicity data (lowest value ≤ 0.01 mg/L) and as the substance is not readily biodegradable, the substance needs to be classified as Aquatic Chronic 1 (H410) with an M-factor of 10, in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.

In conclusion, the substance is classified as Aquatic Acute 1 (H400) and Aquatic Chronic 1 (H410), with an M-factor of 1 and 10 for acute and chronic hazard, respectively, in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
