Conclusion on classification

Environmental classification and labelling of a substance is generally based on data from short-term aquatic toxicity results, the ready biodegradability of the substance and an experimentally determined BCF (or if absent the measured octanol/water partition coefficient). Available adequate chronic toxicity data is also relevant for the assessment of long-term aquatic hazards (Regulation 286/2011/EC).

 

Short-term aquatic toxicity data is available for all three trophic levels (daphnia, algae and fish). Based on valid studies the determined E(L)C50 values are respectively 36.2mg/L, > 40 mg/L and 5.97 mg/L. Since all EC50s are > 1mg/L the substance is not classified for short-term (acute) hazards to the aquatic environment according to the CLP Regulation 1272/2008/EC.

 

Chronic aquatic toxicity data is only available for one trophic level (algae). Therefore, the long-term (chronic) hazard has been assessed based on both:

a) The chronic aquatic toxicity data for algae (ErC10 = 10.1 mg/L) which results in no chronic classification, and

b) The acute aquatic toxicity data for daphnia (EC50 = 36.2mg/l) and fish (LC50 = 5.97 mg/l) and environmental fate data (readily biodegradable and log Kow of 2.0), which results in no chronic classification,

and classifying according to the most stringent outcome

 

Thus it is concluded that the substance is not classified for long-term (chronic) aqautic hazard according to the CLP Regulation 1272/2008/EC & adaptation 286/2011/EC.

According to the old DSD regulation, Directive 67/548/EEC, the substance would also not be classified for environmental hazards.
