Decontamination of toxic chemicals in vehicle interiors using hot air

Abstract

A computer model is presented which describes the desorption of liquid chemicals of intermediate volatility from vehicle interiors. The initial contamination level may be derived by measurement of the concentration of the desorbing chemical vapor as a function of time. The model has been applied to both alkyd and polyurethane painted vehicles and used to determine the residual contamination remaining in vehicles after decontamination with hot air.
