Conclusion on classification

Acute toxicity information for algae and Daphnia is available. The ErC50 for algae is 39.5 mg/l, which is lower than for Daphnia (177 mg/l).

Based on the lowest available acute data for algae with an ErC50 value of 39.5 mg/L the substance does not need to be classified for acute aquatic toxicity.

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 10.6 mg/L. In combination with the substance being readily degradable the substance does not need to be classified for chronic toxicity according to Figure 4.1.1 and Table 4.1.0, (b) ii of the CLP Regulation. When taking into account the acute data of the other trophic level, i.e. Daphnia with an EC50 value of 177 mg/L, in combination with the substance being readily degradable and having a log Kow of 2.1 the substance also does not need to be classified for chronic toxicity according to Figure 4.1.1 and Table 4.1.0, (b) iii of the CLP Regulation.

Overall, it can be concluded that Peomosa does not need to be classified for the environment in accordance with the criteria outlined in Annex I of CLP (1272/2008/EC) and its amendments.
