Conclusion on classification

According to CLP Regulation (EC) No. 1272/2008 including its amendments, the substance needs to be classified as

- Category Acute 1 as in the fish toxicity study an LC50 of 0.1 mg/L was derived (daphnia and algae not more sensitive in acute studies), and thus assigned H400 'Very toxic to aquatic life'.

- Category Chronic 1 as in the fish toxicity study an LC50 of 0.1 mg/L was derived (daphnia and algae not more sensitive in acute studies), and the substance is not biodegradable, and thus assigned H410 'Very toxic to aquatic life with long lasting effects'.

Based on the lowest L(E)C50 value of 0.1 mg/L (fish), an M factor of 10 is assigned for acute toxicity and for chronic toxicity.
