Conclusion on classification

Short-term aquatic toxicity data is available for two trophic levels (daphnia and algae). Based on measured concentrations, the 48h EC50 of daphnia magna was determined to be 1.48 mg/L and 72h ErC50 of Pseudokirchneriella subcapitata to be > 3.56 mg/L. Since both EC50 values are > 1 mg/L, the substance is not classified for short-term 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 hazard has been assessed based on both:

a) The chronic aquatic toxicity data for algae (72 hr ErC10 = 1.46 mg/l), which results in no chronic classification because the value is > 1mg/L, and

b) The acute aquatic toxicity data for daphnia (EC50 = 1.48 mg/L) and environmental fate data (not readily biodegradable, log Kow > 6), which results in a chronic 2 classification,

and classifying according to the most stringent outcome.

 

Thus it is concluded that the substance is classified Aquatic Chronic 2 ( H411) according to the CLP Regulation 1272/2008/EC & adaptation 286/2011/EC.
