Additional information
Conclusion on classification
Short-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and algae). The acute effect values for fish (Danio rerio), invertebrates (Daphnia magna) and algae (Raphidocelis subcapitata) are 0.55 mg/L, 0.32 mg/L and > 0.72 mg/L, respectively. Since the lowest acute toxicity value is < 1 mg/L, the substance needs to be classified as Aquatic Acute 1 (H400) with an M-factor 1, according to EU CLP (EC no. 1272/2008 and its amendments: Table 4.1.0; a).
Chronic toxicity data are available for fish and algae. The long-term toxicity to fish effect value is derived using the LBB/CBB approach and is determined to be 0.055 mg/L. The algae 72-h ErC10 value is 0.41 mg/L. According to CLP Figure 4.1.1, the chronic classification has to be determined based on the chronic values for fish and algae according to Table 4.1.0, (b) i, as well as the acute value for Daphnia according to Table 4.1.0, (b) iii, and the most stringent outcome should be leading:
- The substance is not readily biodegradable and the lowest chronic toxicity value (fish) is > 0.01 but ≤ 0.1 mg/L. Based on this information, the substance needs to be classified as Chronic Cat. 1 according to Table 4.1.0, (b) i.
- The substance is not readily biodegradable, has an experimental lipid-normalised BCF value of > 500 and an acute toxicity value (aquatic invertebrates) of > 0.1 but ≤ 1 mg/L. Based on this information, the substance needs to be classified as Chronic Cat. 1 according to Table 4.1.0, (b) iii.
Overall, it can be concluded that the substance needs to be classified as Aquatic Acute Cat. 1 (H400) and Aquatic Chronic Cat. 1 (H410) with an M-factor of 1 according to EU CLP (EC 1272/2008 and its amendments).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
