EC number: 250-054-6 | CAS number: 30112-70-0
Short-term toxicity to aquatic invertebrates
EC50 (48h) = 6.11 mg/l
Toxicity to aquatic plants other than algae
ErC50 > 100 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 when the following criteria are met:
A )Acute (short-term) aquatic hazard
Category Acute 1: 96 hr LC 50 (for fish) and/or 48 hr EC 50 (for crustacea) 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 availableand 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) and/or 48 hr EC 50 (for crustacea) and/or 72 or 96 hr ErC 50 (for algae or other aquatic plants) ≤ 1 mg/l
Category Chronic 2: 96 hr LC 50 (for fish) and/or 48 hr EC 50 (for crustacea) and/or 72 or 96 hr ErC 50 (for algae or other aquatic plants)> 1 to ≤10 mg/l
Category Chronic 3:96 hr LC 50 (for fish) and/or 48 hr EC 50 (for crustacea) and/or 72 or 96 hr ErC 50 (for algae or other aquatic plants) > 10 to ≤ 100 mg/l
Based on the above results, the Daphnia study provides the lowest toxicity endpoint and therefore will be used for Classification as Aquatic Chronic 2 (H411).
