Additional information
Conclusion on classification
Classification related key information
Biodegradation: not readily biodegradable
Bioaccumulation: No significant bioaccumulation in biota is expected based on a log Pow of 1.43
Acute toxicity:
- Fish: LC50 (96 h): >2000 mg/L
- Aquatic invertebrates: EC50 (48 h): 58 mg/L
- Algae: EC50 (growth rate) = 118 mg/L
Chronic toxicity:
- Algae: EC10 (72 h): 9.4 mg/L
Conclusion on classification
Chloroethane (CAS 75-00-3) is not readily biodegradable. The substance has a low potential for bioaccumulation. The most sensitive acute aquatic toxicity L(E)C50 values is 58 mg/L for Daphnia magna.Adequate chronic data are not available. Thus the substance needs to be classified as chronic 3 according to the 6th ATP of Regulation (EC) No. 1272/2008 (CLP).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
