Conclusion on classification

Sodium trichloroacetate is included in the list of harmonised classifications and labellings and it is classified as Hazardous for the Aquatic Environment, Acute Category 1 and Chronic Category 1.

Algae is the most sensitive species based on results on sodium trichloroacetate and the analogue monochloroacetic acid. These findings support the classification of the substance sodium trichloroacetate as Hazardous for the Aquatic Environment, Acute Category 1. Furthermore, since the substance sodium trichloroacetate is considered as non readily biodegradable, the substance is also classified as Hazardous for the Aquatic Environment, Chronic Category 1.
