Conclusion on classification

According to the CLP Regulation (EC 1272/2008), acute aquatic toxicity is normally determined using a fish 96-hour LC50, a crustacean species 48-hour EC50 and/or an algal species 72- or 96-hour EC50; nevertheless it is also specified in the Regulation that data on other species (e. g. Lemna spp.) shall also be considered if the test methodology is suitable. These species cover a range of trophic levels and are considered as surrogate for all aquatic organisms.

According to the table 4.1.0 of the CLP Regulation (EC n. 1272/2008), a substance for wich adequate chronic toxicity data are not available shall be classified as

Aquatic Acute 1 when:

96 hr LC50 (for fish)≤1 mg/l and/or

48 hr EC50 (for crustacea)≤1mg/l and/or

72 or 96 hr ErC (for algae or other aquatic plants)≤1 mg/l

 Aquatic Chronic 1 when:

96 hr LC50 (for fish)≤1 mg/l and/or

48 hr EC50 (for crustacea)≤1mg/l and/or

72 or 96 hr ErC (for algae or other aquatic plants)≤1 mg/l 

 

Aquatic Chronic 2 when:

96 hr LC50 (for fish) > 1 <= 10 mg/l and/or

48 hr EC50 (for crustacea)> 1 <= 10 mg/l and/or

72 or 96 hr ErC (for algae or other aquatic plants)> 1 <= 10 mg/l 

Aquatic Chronic 3 when:

96 hr LC50 (for fish) > 10 <= 100 mg/l and/or

48 hr EC50 (for crustacea)> 10 <= 100 mg/l and/or

72 or 96 hr ErC (for algae or other aquatic plants)> 10 <= 100 mg/l

and the substance is not rapidly degradable and/or the experimentally determined BCF ≥ 500 (or, if absent, the log K ow ≥ 4)

Based on the results of the anlaogue substances and the read across considerations the substance is not classified for the aquatic compartment.
