Additional information
Conclusion on classification
Short-term aquatic toxicity data are available for freshwater species of three trophic levels (fish, aquatic invertebrates and aquatic algae). The acute effect values for fish (D. rerio), daphnids and algae (D. subspicatus) are 5.3 mg/L, 16.2 mg/L and 1.52 mg/L, respectively. The substance does not need to be classified for acute aquatic hazard. Long-term aquatic toxicity data are available for the same three trophic levels with chronic effect values for fish (P. promelas), daphnids and algae (D. subspicatus) are 0.67 mg/L, 0.84 mg/L and 0.54 mg/L, respectively. As the substance is not readily biodegradable and the lowest chronic effect value is in the range of 0.1 - 1 mg/L, the substance is classified as chronic 2 (H411)
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).
