Conclusion on classification

Based on the results from the available studies with registered or structurally similar substances , Daphnia has been identified to be the most sensitive species. The short-term 48 h EC50 value based on a study with the structural similar substance, TMAC HT, was determined to be 0.0091 mg a.i./L (nominal) and the lowest long-term 21-day NOEC value based on a source study with C12-16 ADBAC in Daphnia was at 0.00415 mg/L (measured). Therefore, based on the available results, the registered substance TMAC T warrants a 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 100 for acute and 1 for chronic toxicity.
