Additional information
Conclusion on classification
The results from aquatic toxicity studies are as follow:
- Short-term toxicity to fish. Key study: LC50 (96h) = 696.76 mg/L (basis for effect: mortality) (read-across from the analogue substance acetone oxime).
- Short-term toxicity to aquatic invertebrates: Key study: EC50 (48h) = 678.76 mg/L (basis for effect: mobility) (read-across from the analogue substance acetone oxime)
- Toxicity to aquatic algae: Key study: EC50 (72h) = 315.36 mg/L and NOEC (72h) = 62.34 mg/L (basis for effect: growth rate) (read-across from the analogue substance acetone oxime).
- Toxicity to microorganisms:Key study: EC50 (3h) > 239.78 mg/L (activated sludge, basis for effect: respiration rate) (read-across from the analogue substance Wasox-VMAC2).Key study: EC50 (3h) > 248.06 mg/L (activated sludge, basis for effect: respiration rate) (read-across from the analogue substance Wasox-MMAC2).
Based on the results from the aquatic toxicity tests, the substance the substance EAC3 is not classified for aquatic toxicity according to CLP Regulation (EC) No. 1272/2008.
