Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Biodegradation in soil: Weight of evidence: experimental results from independent peer reviewed publications. Biodegradation is not an important environmental fate process in soil. The half-life was about 28-30 days.
Key value for chemical safety assessment
Additional information
Weight of evidence: experimental results: Biodegradation is not an important environmental fate process in soil. The half-life was about 28-30 days.
The degradation was highest in the 0 -5 cm-horizon (higher organic matter content, best nutrient supply). For most soils, the degradability decreased already in the 20-25 cm-horizon, so that the danger of a further leaching of dissolved sodium trichloroacetate the groundwater exists at very high dosing.
The degradation diminished with decreasing pH. The microbial activity also affected the degradation rate.
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.
