Conclusion on classification
According to the CLP Regulation (EC 1272/2008), the threshold for classification is 1 mg/l and 100 mg/l for acute toxicity and chronic toxicity, respectively.
In particular, classification for short-term (acute) aquatic hazard Category Acute 1 applies if:
96 hr LC50 (for fish) ≤ 1 mg/l and/or
48 hr EC50 (for crustacea) ≤ 1 mg/l and/or
72 or 96 hr ErC50 (for algae or other aquatic plants) ≤ 1 mg/l.
For non-rapidly degradable substances for which adequate chronic toxicity data are available, classification in:
- Category Chronic 1 applies if:
Chronic NOEC or ECx (for fish) ≤ 0.1 mg/l and/or
Chronic NOEC or ECx (for crustacea) ≤ 0.1 mg/l and/or
Chronic NOEC or ECx (for algae or other aquatic plants) ≤ 0.1 mg/l
- Category Chronic 2 applies if:
Chronic NOEC or ECx (for fish) ≤ 1 mg/l and/or
Chronic NOEC or ECx (for crustacea) ≤ 1 mg/l and/or
Chronic NOEC or ECx (for algae or other aquatic plants) ≤ 1 mg/l
Based on available data, the substance is not classified for acute and chronic aquatic toxicity according to the CLP Regulation EC No.1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
