SPMDs are unique among passive air samplers in their ability to sample both vapor phase pollutants and compounds present in particulate phase. This is caused by sticky lipid layer formed at the outer surface of the polyethylene membrane, To understand the role of this lipid layer in the pollutant uptake mechanism, a mathematical model has been proposed. On the base of the results obtained the response of the surface lipid layer is not integrative, therefore it is recommended to remove this layer before dialysis of the exposed SPMD.
