Conclusion on classification
Short-term toxicity tests for algae and Daphnia are available for the substance. In addition, one reliable EC10 value is available for long-term toxicity (algae). The EC50 value for Daphnia is 6.5 mg/l, whereas the ErC50 for algae is 8 mg/L. The EC10 value for algae is 2.75 mg/L. Based on the lowest available acute data for Daphnia with an EC50 value of 6.5 mg/L the substance does not need to be classified for acute aquatic toxicity (CLP, 2011: Table 4.1.0; a). As one chronic value is available for algae the chronic C&L needs to be derived on both chronic and acute toxicity data and the most stringent outcome needs to be taken into consideration. The only chronic value available is the ErC10 for algae being 2.75 mg/L. In combination with the substance being not readily degradable this would lead to no classification. In view of the acute Daphnia result of 6.5 mg/L, the substance being not readily biodegradable and the log Kow of 3.5 the substance needs to be classified for chronic toxicity according to Figure 4.1.1 and Table 4.1.0, (b) iii, resulting in Aquatic Chronic 2.
Overall, it can be concluded that Damascol needs to be classified with Aquatic Chronic 2 (H411) according to Regulation 1272/2008/EC and its updates.Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
