Additional information
Conclusion on classification
Short-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and algae). The acute effect values for fish (Danio rerio), daphnids (Daphnia magna) and algae (Desmodesmus subspicatus) are 0.3 mg/L, 0.163 mg/L and 0.03 mg/L, respectively. The substance needs to be classified as Aquatic Acute 1 (H400), with a M-factor of 10.
Long-term aquatic toxicity data are available only for aquatic algae for which an ErC10 of 0.0143 mg/L was determined. Based on this chronic data and the substance’ non-readily biodegradability, the substance needs to be classified as Aquatic Chronic 1 (H410), with a M-factor of 1.
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 between 0.01 - 0.1 mg/L), the substance being not readily biodegradable and an (estimated) log Kow of 7.51 (no experimental BCF available) the substance needs to be classified as Aquatic Chronic 1, with a M-factor of 10. Therefore, based on short-term toxicity data, the substance is classified as Aquatic Chronic 1 (H410) with a M-factor of 10, as in accordance with EU Classification, Labelling 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.
