Description of key information

Short-term toxicity to fish

LC50 = 35 mg/l

Short-term toxicity to aquatic invertebrates

EC50 = 0.266 mg/l

Long term toxicity to aquatic invertebrates

LOEC = 1.5 mg/l

Toxicity to aquatic plants other than algae

ErC50 =   6.45 (5.09 – 7.88) mg/L based on frond number

ErC50 = 2.99 (2.48 – 3.66) mg/L based on dry weight

Additional information

Justification for classification or non-classification

According to the CLP Regulation (EC n. 1272/2008), Part 4: Environmental Hazards, a substance shall can be classified for hazardous to the aquatic environment when the following criteria are met:

Category Acute 1:

96 hr LC 50 (for fish) < 1 mg/l and/or

48 hr EC 50 (for crustacea) < 1 mg/l and/or

72 or 96 hr ErC 50 (for algae or other aquatic plants) < 1 mg/l

Substances for which adequate chronic toxicity data are not available and the substance is not rapidly degradable and/or the experimentally determined BCF ≥ 500 (or, if absent, the log K ow ≥ 4)

Category Chronic 1:

96 hr LC 50 (for fish) > 0.1 to ≤ 1 mg/l and/or

48 hr EC 50 (for crustacea) > 0.1 to ≤ 1 mg/l and/or

72 or 96 hr ErC 50 (for algae or other aquatic plants) > 0.1 to ≤ 1 mg/l

Despite the substance has chronic data available, they are not considered as sufficient for the assesment and the short -term toxicity to Daphnia study provides the lowest value that will be used for Classification: Category Chronic 1 and Category Acute 1 (H410).
