Conclusion on classification

Adequate short-term aquatic toxicity data are available for two trophic levels: (aquatic invertebrates: Daphnia magna and aquatic algae: Pseudokirchneriella subcapitata), which have EC50 values of 0.43 and >0.49 (max water solubility), respectively. Based on the acute Daphnia value the substance needs to be classified for acute aquatic hazard, Category Acute 1, H400: Very toxic to aquatic life (EU CLP 2008, and its amendments: Table 4.1.0 (a)).

As no adequate chronic toxicity data are available (Algae EC10 > 0.49 mg/L), acute toxicity data needs to be assessed for long term aquatic toxicity in combination with biodegradability and/or log Kow (EU CLP 2008, and its amendments: Figure 4.1.1. and Table 4.1.0(b)(iii)). In view of the substance being not readily biodegradable, having a log Kow of 5.7 and the lowest acute toxicity data being available for Daphnia with an EC50 value of <1.0 mg/L, the substance needs to be classified as Category Chronic 1 according to Table 4.1.0(b)(iii). Therefore for long-term aquatic hazard, the substance needs to be classified as Category Chronic 1, H410: Very toxic to aquatic life with long lasting effects, according to EU CLP (EC no. 1272/2008 and its amendments).
