Conclusion on classification
Based on the results from the available studies with the read across substances, daphnia has been identified to be the most sensitive species. The short-term 48 h EC50 value for the test substance in Daphnia was determined to be 0.016 mg a.i./L (nominal) and the lowest long-term 21-day NOEC value based on studies with read across substance, C12-16 ADBAC, in daphnia was at 0.00415 mg/L (measured). Therefore, based on the available results, the test substance C12-14 ADBAC warrants classification as ‘Aquatic Acute 1’ and ‘Aquatic Chronic 1; H410: Very toxic to aquatic life with long-lasting effects’ according to EU CLP criteria (Regulation 1272/2008/EC). M factors to be applied are 10 for acute and 1 for chronic toxicity.
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.
