Additional information

Conclusion on classification

Data are available from short term toxicity tests with organisms of three trophic levels. The EL-value for the most sensitive species Daphnia magna was 26.3 mg/L (48 hours). Since the substance is not readily biodegradable and shows some potential for bioaccumulation (log Kow = 4.2) this results in a classification as aquatic chronic 3 according to GHS regulation 1272/2008.
