Description of key information
Additional information
Carbon tetrachloride has a moderate potential for adsorption in soil, from the results of an experimental study (Koc about 115). An experimental determination of HLC has been carried out by Munz (1987), who determined H = 2370 Pa.m3/mol at 20°C. A supporting value of 2990 Pa.m3/mol at 25°C can be found in a handbook.
According to fugacity model level I, more than 99% of the substance will partition to the atmosphere (Thompson et al., 2004).
According to a fugacity model level III, at steady state, with default values, the partitioning is as follows (Epiwin V.4):
Volatilization from Water:
Henry LC: 0.0276 atm-m3/mole (Henry experimental database)
Half-Life from Model River: 1.292 hours
Half-Life from Model Lake : 118.1 hours (4.92 days)
Removal In Wastewater Treatment:
Total removal: 91.57 percent
Total biodegradation: 0.03 percent
Total sludge adsorption: 2.02 percent
Total to Air: 89.51 percent
(using 10000 hr Bio P,A,S)
Level III Fugacity Model:
Mass Amount Half-Life Emissions
(percent) (hr) (kg/hr)
