Description of key information

Short-term toxicity to fish:

KS - LC50 - geometrical mean (96h) = 12.5 mg/l

Short-term toxicity to aquatic invertebrates:

KS - EC50 (48h) = 0.0955 mg/l

SS - EC50 (24h) = 0.18 mg/l

Toxicity to aquatic algae and cyanobacteria:

SS - EC50 (72h) = 0.21 mg/l as growth rate

Toxicity to aquatic plants other than algae:

KS - ErC50 = 3.52 mg/l as growth rate of frond number

Toxicity to microorganisms:

KS - EC50 (3h) = 13.1 mg/l

SS - EC50 = 5.2 mg/l

Additional information

Decision on classification

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 1 (H410) 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

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

Based on the available information, the substance is classified in category 1 for aquatic acute toxicity (H400) and aquatic chronic toxicity (H410).
