[A personal diffusion sampler for evaluating time weighted exposure to gaseous hydrogen sulfide (author's transl)].
A simple badge type diffusion tube, 35 mm photo film plastic case, was used for evaluating time-weighted exposure to H2S using reagent impregnated filters (Whatman No. 1). The black shade of the reagent filter, 10% Pb(OAc)2 and 2% AgNO3 under the concentration of H2S below 20 ppm for 2 to 4 hours agreed inversely to the diffusion length of the tube, and lineally well correlated with dose-time unit (C X T) and the theoretical value of diffusion. The device was proved to be capable of being used in realistic working conditions provided that there is no extreme fluctuations of H2S.
