Conclusion on classification

The environmental classification of T001141 is currently not harmonised according to the CLP Regulation (EC) 1272/2008. Based on available acute aquatic toxicity data, the lowest valid effect concentration for freshwater aquatic organisms is 0.21 mg/L (LC50 for fish). Based on the available acute data, the substance should be classified for acute toxicity following Annex I, table 4.1.0 a of the CLP regulation. In the algal growth inhibition study, the ErC10 and NOErC for algae were 0.16 and 0.048 mg/L respectively. Taking into account the acute and chronic algae toxicity data as well as the fact that the substance is not rapidly degradable and its log Kow is < 4, the substance should be classified as Aquatic Acute 1 and Chronic 1 under the CLP Regulation.
