Abstract : The concentrations of chemical contamination desorbing from alkyd and polyurethane painted vehicles after exposure to sun and wind under winter conditions have been measured. A computer model has been used to determine the residual contamination level after weathering. The removal efficiency under winter conditions is compared with that under summer conditions and is shown to be approximately one eighth as effective. The weathering process is also compared with active clean-up processes involving detergent/steam and C8 emulsion/steam. The combination of C8 emulsion and steam is shown to be the most effective decontamination process.
