Conclusion on classification
DSD (Council Directive 67/548/EEC):
Based on the results of the acute toxicity tests to aquatic organisms (most sensitive species are daphnia with a 48-h EC50 of 1.26 mg/L) and considering the results of ready biodegradability testing (not readily biodegradable and for bioaccumulation (BCF = 939), dichloromethylbenzene has to be classified as toxic to aquatic organisms, with R51/53 (“toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. ”).
CLP (Regulation (EC) No 1272/2008):
Based on the results of the chronic toxicity tests to aquatic organisms (most sensitive species are fish with a PNEC of 0.078 mg/L) and considering the results of ready biodegradability testing (not readily biodegradable , dichloromethylbenzene has to be classified as H410 (“Very toxic to aquatic life with long lasting effects”: Chronic Category 1).
