Conclusion on classification

Acute:

Fish are the most sensitive species to the acute toxic effects of the test item with an acute EC50 of 67.8 mg/L for zebrafish and an EC50 in the range of 10 - 100 mg/L for fathead minnow. Thus, the substance has not to be classified for acute aquatic toxicity according to Directive 67/548/EEC (DSD) and Regulation (EC) No 1272/2008 (CLP/GHS).

Chronic: Classification of the test item is based on the studies with freshwater algae (desmodesmus subspicatus), duckweed (Leman gibba) and fish species (Danio rerio, Pimephales promelas) which are the most sensitive species to the effects of the test item. For the algae the 72 hour EC50 was determined to be in the range of 10 - 100 mg/L; for duckweed the 7 day EC50 was determined to be 10.7 mg/L; for Danio rerio and Pimephales promelas the 96 hour LC50 were determined to be 67.8 mg/L and in the range of 10 - 100 mg/L, respectively. As the test item is not ready biodegradable, the substance is classified as chronic aquatic cat. 3 (H412): Harmful to aquatic life with long lasting effects according to Regulation (EC) No 1272/2008 (CLP/GHS) and as R52/53 Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment according to Directive 67/548/EEC (DSD).
