Conclusion on classification

Trichloroacetic acid 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 are very sensitive to the analogues sodium trichloroacetate and monochloroacetic acid based on the reported results. These findings support the classification of the substance trichloroacetic acid as Hazardous for the Aquatic Environment, Acute Category 1. Furthermore, since the substance trichloroacetic acid is considered as non readily biodegradable, the substance is also classified as Hazardous for the Aquatic Environment, Chronic Category 1.
