Conclusion on classification

Short-term aquatic toxicity data are available for two trophic levels (aquatic invertebrates and aquatic algae). The acute effect value, EC50 for Daphnia is 24 mg/l and for the ErC50 for Algae is 9.7 mg/l. Based on the lowest available acute data, for algae the substance does not need to be classified for acute aquatic hazard (CLP 2008, and its amendments: Table 4.1.0 (a). As for only one trophic level chronic toxicity data are available, both chronic toxicity data (in combination with biodegradability) and acute toxicity data (in combination with biodegradability and/or Log Kow) need to be assessed and the most stringent outcome needs to be applied for long-term hazard classification (CLP 2008, and its amendments: Figure 4.1.1.). In view of the substance being readily biodegradable, log Kow of 3.0 and the chronic available value of the ErC10 of algae being 2.8 mg/L, the substance does not need to be classified for long-term aquatic hazard according to Table 4.1.0(b)ii. Based on the acute toxicity data of the other trophic level, being acute Daphnia EC50 of 24 mg/l, and the substance being readily biodegradable and having a Log Kow of 3, the substance does not need to be classified 4.1.0(b)iii according to Regulation 1272/2008/EC (CLP) and its amendments.
