Description of key information

Fish: LC50 (96h) between 10 and 100 mg/l

Aquatic invertebrates: EC50 (48h) > 101 mg/l

Aquatic algae: EC50 (72h) > 100 mg/l

Additional information

According to the CLP Regulation (EC 1272/2008), a substance shall be classified as category acute 1 (H400) when:

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

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

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

 

Moreover, if adequate chronic toxicity data is not available, a substance shall be classified as category chronic 3 (H412) 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 Kow ≥ 4).

The decision on classification was derived from available experimental data. A classification in category 3 for aquatic chronic toxicity (H412) was based on results on fish, i.e. LC50 (96 h) between 10 - 100 mg/l.
