Conclusion on classification

Acute aquatic toxicity data are available for three trophic levels (fish, aquatic invertebrates and algae). The lowest acute toxicity value is a 96 -h LC50 of > 117 mg/L in fish (C. carpio). Since the lowest acute toxicity value is > 1 mg/L, the substance does not need to be classified as acute aquatic toxic according to EU CLP (EC no. 1272/2008 and its amendments: Table 4.1.0; a). A chronic aquatic endpoint is available only for freshwater algae (R. subcapitata) in which a 72-h NOErC of 170 mg/L was determined. Regarding the adequate chronic aquatic toxicity data the substance has a chronic toxicity value of > 1 mg/L. Furthermore, the substance is not readily biodegradable. According to CLP Figure 4.1.1, the chronic classification has to be determined based on the chronic value for algae according to Table 4.1.0, (b) i, as well as the acute value for Daphnia and fish according to Table 4.1.0, (b) iii, and the most stringent outcome should be leading:


- The substance has a chronic toxicity value of > 1 mg/L. Based on this information, the substance does not need to be classified according to Table 4.1.0, (b) i.
- The lowest acute toxicity value > 100 mg/L and the log Kow of the substance is 1.6. Based on this information, the substance does not need to be classified according to Table 4.1.0, (b) iii.


In conclusion, the substance is not classified for acute and chronic environmental hazard, in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
