Additional information
Conclusion on classification
The results from the aquatic toxicity studies are as follows:
LC50 (96 h) fish = 0.72 mg/l (measured concentration).
EC50 (48 h) aquatic invertebrates = 0.72 mg/l (measured concentration).
Based on the results from the aquatic toxicity (at least one value below 1 mg/l) and since the substance is not readily biodegradable and has a log Pow greater than 4, the substance is classified as follows:
- according to Directive 67/548/EEC the substance is classified as N, R50/53.
- according to the CLP Regulation 1272/2008 the substance is classified as Acute Category 1 and Chronic Category 1.
Based on the available information, the M-factor is 1.
