Abstract
ABSTRACT
Volatilization of selected toxic volatile organic compounds (VOCs) in slow rate land treatment (SR) systems was studied in laboratory soil columns.
Chloroform, 1,1,1-trichloroethane, trichloroethylene, and 1,2-dichlorobenzene volatilized 29 to 55 percent; carbon tetrachloride, dichlorobromomethane, dibromochloromethane, tetrachloroethylene, and 1,3-dichlorobenzene to a lesser extent (15-30 percent); and bromoform volatilized less than 10 percent. The soil reduced volatilization losses by 10 to 100 fold compared to theoretical volatilization from water. The soil type and V0C concentration did not affect volatilization, but volatilization increased with temperature.
