Conclusion on classification

Short-term aquatic toxicity data are available for three trophic levels (fish, aquatic invertebrates, and algae). The lowest observed acute effect concentration was 105 mg/L in daphnids (Daphnia magna). Consequently, the substance does not need to be classified for acute aquatic hazard.

Long-term aquatic toxicity data are available only for aquatic algae, for which no effect level could be derived due to the absence of toxic effects (ErC10 > 222 mg/L). Based on this chronic data, the substance does not need to be classified for chronic hazard.

  

As only one reliable long-term toxicity endpoint is available, chronic classification needs to be based on both chronic and acute data of which the most stringent outcome is used for the final classification. As the (lowest) acute effect value is > 100 mg/L, the substance does not need to be classified for a chronic hazard based on acute data. Therefore, the substance is not classified for aquatic hazard as accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
