Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The half-life for disappearance of carbon tetrachloride in both sterile and non-sterile systems was around 5 days, indicating that volatilization was the likely removal process

Key value for chemical safety assessment

Half-life in soil:
5 d
at the temperature of:
20 °C

Additional information

Anderson et al (1991) studied the loss of carbon tetrachloride from two different soil types, a silt loam 1.49% organic carbon) and a sandy loam (0.66% organic carbon). Carbon tetrachloride was applied to the soil (in a mixture with 14 other compounds) at a concentration of 100 mg/kg (dry weight) and the soil was incubated in the dark at 20 deg C for 7 days.  The half-life for disappearance of carbon tetrachloride in both sterile and non-sterile systems was around 5 days, indicating that volatilization was the likely removal process. Carbon tetrachloride is likely to volatilize rapidly from soil.  Absorption of CTC into soil and sediment may occur to a small extent but CTC is likely to be mobile in such media.
