Determination of lindane vapour in air by passive sampling. Part I. Development of the passive sampling device and measurement of the diffusion coefficient of lindane in air

Abstract

The development of a passive sampling device for the determination of low concentrations of lindane (γ-hexachlorocyclohexane) vapour in air is described. The sampler consists of an open glass tube mounted in a Perspex base that contains Chromosorb 102 sorbent and collects lindane vapour by diffusion according to Fick's law. The diffusion coefficient of lindane in air is determined by exposing tubes to standard atmospheres of lindane vapour generated in the laboratory. Good agreement with the theoretical value was obtained.
