Comparison of Advective and Diffusive Transport of Svocs through Cloth for Indoor Conditions

Abstract

Clothing fabrics may influence dermal uptake of pollutants by acting as a transport barrier, but also as a reservoir of adsorbed compounds. Transport to and through fabrics is complex, but simplifications for indoor environments would improve exposure estimates by requiring less information about conditions. This study applies a Peclet number analysis to a range of indoor activities to determine when diffusion, advection or both are important for transport of SVOCs through clothing. Our findings suggest that for situations where an occupant is sitting, standing or walking slowly, diffusion dominates. For other indoor conditions, both advection and diffusion must be considered, unless very permeable, thin clothing is worn.
