Additional information
Conclusion on classification
Short-term fish, invertebrate and algae toxicity studies are available on the test substance, C14 ADBAC and a long-term daphnia and fish studies are available with the read across substance, C12-6 ADBAC. Based on short-term tests,daphniahas been identified to be the most sensitive species with the lowest 48 h EC50 value determined to be at 0.0164 mg/L (nominal). Out of the two long-term tests, algae have been identified as the most sensitive species with the lowest NOEC value of 0.00342 mg/L. Therefore, based on the available results and considering that the substance is readily biodegradable with low bioaccumulation potential, C14 ADBAC requires classification as Aquatic Acute 1 and Aquatic Chronic 1; H410: Very toxic to aquatic life with long-lasting effects according to Regulation EC 1272/2008. 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).
