Description of key information

Toxic effect on daphnia and algae.

Not toxic for fish.

Additional information

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), asubstance 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 on the available tests on acute toxicity to daphnia magna and to algae, the tested substance showed toxic effects in all of the availabale tests and needs to be classified as Aq. Chronic 3, H412. The tested substance does not show any toxic effects on fish.
