Additional information
Conclusion on classification
Short-term aquatic toxicity data are available for two trophic levels (fish and algae). The acute effect values for fish (Oryzias latipes) and algae (Raphidocelis subcapitata) are 0.97 mg/L and 4.54 mg/L, respectively. Since the lowest acute toxicity value is < 1 mg/L, the substance needs to be classified as Aquatic Acute Category 1 (H400) with 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 three trophic levels (fish, invertebrate and algae). The long-term toxicity value for fish, invertebrate and algae were 0.074, 0.678 and 2.45 mg/L, respectively. The substance is not readily biodegradable and its lowest chronic toxicity value was > 0.01 but ≤ 0.1 mg/L. Based on this information, the substance needs to be classified as Chronic Cat. 1 (H410) with M-factor 1 according to EU CLP (EC 1272/2008 and its amendments: Table 4.1.0, (b) i).
