Weight of evidence: Experimental results without analytical monitoring and ECOSAR calculations.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 0.595 mg/L
Additional information
Experimental results are available from a study conducted in fish with ethyl chloroacetate. The LC50 for fish was concluded to be 1.48 mg/l. However, no analytical monitoring was conducted during the study. Therefore, there is no evidence that the concentration of the substance was maintained during the test. Ethyl chloroacetate is included in the list of harmonised classifications and labellings and it is classified as Hazardous for the Aquatic Environment, Acute Category 1. ECOSAR calculations were conducted for both methyl chloroacetate and ethyl chloroacetate. The outcome of this calculations is that the LC50 for fish for both substances is below 1 mg/l. These results support the classification for ethyl chloroacetate as Hazardous for the Aquatic Environment, Acute Category 1.
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.
