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 two trophic levels (daphnia and algae). The lowest short-term L(E)C50 is for algae: the 72-hour ErC50 is 3 mg/l. Since the EC50 is > 1mg/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 (NOEC = 1.1 mg/L, 72 hr EC10 = 1.1 mg/l, based on growth rate), which results in no chronic classification because the Chronic NOEC or EC10 is > 1mg/L, and

b) The acute aquatic toxicity data for daphnia (EC50 = 11 mg/L) and environmental fate data (not rapidly biodegradable, log Kow of 3.1), which results in a Category Chronic 3 classification,

and classifying according to the most stringent outcome.

 

Thus it is concluded that the substance is classified Aquatic Chronic 3 (H412) according to the CLP Regulation 1272/2008/EC & adaptation 286/2011/EC.

 

Under the old DSD regulation the substance would be classified as R51/53 (toxic to aquatic organisms and may cause long-term adverse effects in the aquatic environment) based on the lowest EC50 of 3 mg/L and environmental fate data (not readily biodegradable and log kow of 3.1).
