20 °C

Additional information

Various assessments of the propensity to biodegrade in general soil and landfil soil was undertaken. Review of the data indicates that CFC-12 will degrade slowly under anaerobic conditions, but not under aerobic conditions. The value proposed above is for degradation under conditions within peat. The overall conclusion is that the substance does not meet the definition of "readily biodegradable" although it will be removed from the soil compartment via anaerobic degradation over time.
