Conclusion on classification
Acute toxicity key values for C12-14 AS Zn:
- For fish: 96h LC50 (B. rerio, mortality) = 4.56 mg a.i./L (nominal concentration, OECD 203)
- For invertebrates: 48h EC50 (D. magna, mobility) = 0.948 mg a.i./L (nominal concentration, OECD 202)
- For algae: 72h EC50 (P. subcapitata, growth rate) = 0.747 mg a.i./L (nominal concentration, OECD 201)
Chronic toxicity key values for C12-14 AS Zn:
- For algae: 72h EC10 (P. subcapitata, growth rate) = 0.226 mg a.i./L (nominal concentration, OECD 201)
For microorganisms: 3h EC50 (activated sludge, respiration rate) > 100 mg a.i./L (nominal concentration, OECD 209)
Classification justification according to CLP:
Based on the data above, C12-14 AS Zn is considered to be rapidly degradable and has a low potential for bioaccumulation. The acute aquatic toxicity L(E)C50 is below 1 mg/L for aquatic invertebrates and algae. The chronic EC10 value for algae is between 0.1 and 1 mg/L. C12-14 AS Zn therefore needs to be classified as environmental hazard Acute Cat. 1 and Chronic Cat. 3 according to Regulation (EC) No.1272/2008 (6th ATP) and Regulation (EU) No. 286/2011 (2nd ATP).
M-factor for acute aquatic toxicity: 1
M-factor for chronic aquatic toxicity: does not need to be assigned
