Conclusion on classification

Short-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and algae). The acute effect values (as loading rates) for fish (Chinese rare minnow), daphnids and algae (Daphnia magna and Pseudokirchneriella subcapitata) are 5.73 mg/L, 93 mg/L and 116 mg/L, respectively. 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 an ErL10 of 67.02 mg/L was determined. 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.

Based on the chronic data (ErL10 of 67.02 mg/L) and the substance’ readily biodegradability, the substance does not need to be classified. Regarding acute toxicity, since the substance is readily biodegradable and has a log Kow of -2.01 (no experimental BCF is available), the substance does not need to be classified. Therefore, based on both acute and chronic data, the substance does not need to be classified according to Regulation 1272/2008/EC (CLP).
