Conclusion on classification
Acute toxicity: The 96 -h LC50 for fish was determined to be 1.7 mg/L using Oncorhynchus mykiss, the 48 -h EC50 for Daphnia magna was determined to be 2.5 mg/L and the ErC50 (24 -48h) for algae (Scenedesmus subspicatus) was determined to be 42 mg/L. According to CLP, Annex I, Section 4.1, Table 4.1.0, in order to classify a substance as Acute 1, a L(E)C50 value for one of the trophic levels must be <= 1mg/L. As all the L(E)C50 values are >1 mg/L, classification for Acute aquatic toxicity is not required.
Chronic toxicity: The 33-d NOEC in an OECD TG 210 study using Pimephales promelas was reported as 0.455 mg a.i./L based on post-hatch survival. The 21-d NOEC in an OECD TG 211 study using Daphnia magna was reported as >= 2 mg a.i./L based on mortality and reproduction. The 72-h NOEC for algae (Scenedesmus subspicatus) was reported as 15 mg/L (OECD TG 201, EU Method C.3). The substance is readily biodegradable. The substance is classified according to CLP, Annex I, Section 4.1, Table 4.1.0 as Aquatic Chronic 3.
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.
