Conclusion on classification

Short-term toxicity tests for algae and Daphnia are available for the substance. The EC50 value for Daphnia is 0.56 mg/l, whereas the ErC50 for algae is between 1 and 10 mg/L (9.5 mg/L). Based on the lowest available acute data for Daphnia with an EC50 value of 0.56 mg/L, the substance needs to be classified as Acute Category 1 according to Table 4.1.0 (a) of CLP.

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 EC10 for algae being 5.0 mg/L. In combination with the substance being rapidly degradable, this would not lead to classification according to Table 4.1.0 (b) (ii) of CLP.

In view of the acute Daphnia result of 0.56 mg/L, the substance being rapidly biodegradable and the log Kow of 3.2 (so <4), the substance does not need to be classified for chronic aquatic toxicity according to Figure 4.1.1 and Table 4.1.0, (b) (iii).

Overall, it can be concluded that the test substance needs to be classified as aquatic Acute Category 1 (H400), in accordance with the criteria outlined in CLP (1272/2008/EC) and its amendments.
