Additional information
Conclusion on classification
Short-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and algae). The acute effect value for fish (Leuciscus Idus) is in between 280 and 600 mg/L. Effect values for daphnids and algae (Daphnia magna and Pseudokirchniriella subcapitata) are 16.76 mg/L and 8.53 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 ErC10 of 5.11 mg/L was determined. Based on this chronic data and the substance’ non-readily biodegradability, 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. Regarding acute data (lowest acute value in the range of 1 - 10 mg/L), the substance being not readily biodegradable and a log Kow of -3.51 (no experimental BCF available) the substance needs to be classified as Aquatic Chronic 2. Therefore, based on short-term toxicity data, the substance is classified as Aquatic Chronic 2 (H411) as in accordance with EU Classification, Labeling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
