EC number: 947-929-6
CAS number: -
Short-term toxicity to aquatic invertebrates
EC50 = 146 mg/L
Toxicity to aquatic plants other than algae
ErC50 = 50 mg/L
Justification for classification or non-classification
According to the CLP Regulation (EC n. 1272/2008), Part 4: Environmental Hazards, the substances can be classified for hazardous to the aquatic environment (fish toxicity) when the following criteria are met:
A) Acute (short-term) aquatic hazard
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
B) Long-term aquatic hazard
(iii) Substances for which adequate chronic toxicity data are not available
Category Chronic 3:
96 hr LC 50 (for fish) > 10 to ≤ 100 mg/l and/or
48 hr EC 50 (for crustacea) > 10 to ≤ 100 mg/l and/or
72 or 96 hr ErC 50 (for algae or other aquatic plants) > 10 to ≤ 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 above results the Lemna study provides the lowest toxicity endpoint and will be used for Classification. Therefore the test substance is Classified as Category Chronic 3.
