Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The relatively high values for the Henry's law constant and the vapour pressure of chloroform indicate that the substance is likely to be predominantly present in the air compartment when released into the environment. Due to its physico-chemical properties, chloroform in soil or surface water volatilises readily; at equilibrium, greater than 99 % is expected to partition to the atmosphere (Zok et al. 1998). Due to chloroform's water solubility, some wet deposition of atmospheric chloroform may occur, but subsequent revolatilisation is likely to be extensive (Diamond et al. 1994). Smaller amounts of environmental chloroform can be found in the aquatic environment. Chloroform has a low affinity for organic carbon (low Koc) and lipids (low Kow). Chloroform thus may readily pass through sandy soils or sediments and may reach the groundwater.
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.
