Additional information
Conclusion on classification
Proposal for CLP classification: Aquatic Chronic 3, H412
Based on data from acute aquatic toxicity tests:
96 hr LC50 for fish (Oncorhynchus mykiss) is 157 mg/L and
48 hr EC50 for crustacea (Daphnia magna) is 54.9 mg/L (Chronic Category 3: EC50 > 10 to ≤ 100 mg/L) and
72 hr ErC50 for algae (Desmodesmus subspicatus) is 78.3 mg/L (Chronic Category 3: ErC50 > 10 to≤100 mg/L) and 72 hr ErC10 for algae (Desmodesmus subspicatus) is 40.2 mg/L.
The substance is not readily degradable and the log Kow is </= 4.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
