Materials and methods

Principles of method if other than guideline:

The loss of carbon tetrachloride from two different soil types was determined. CTC 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 °C for 7 days.

Type of study:

volatility

Media:

soil - air

Applicant's summary and conclusion

Conclusions:

CTC is volatilized from soils with a DT 50 of about 5 days.

Executive summary:

Anderson et al (1991) studied the loss of CTC from two different oil types, a silt loam 1.49% organic carbon) and a sandy loam (0.66% organic carbon). CTC 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 °C for 7 days. The half-life for disappearance of CTC in both sterile and non-sterile systems was around 5 days, indicating that volatilization was the likely removal process.
