Abstract

In this study, acidic/basic gas and particle concentrations determined with a porous-metal denuder and other samplers, that is, silica gel tube, impinger, honeycomb denuder system (HDS), Marple personal cascade impactor, and filter cassette, were compared in the ambient environment and different industrial sites in Taiwan. Results show that the concentrations determined by the denuder are very close to those of other samplers, with excellent correlation. The denuder also was tested successfully to determine H ₂SO₄ size distribution in a lead-acid factory. One-way ANOVA shows no significant differences (P > 0.05) between the porousmetal denuder (PDS) and other samplers. The denuder is compact in size and suitable for sampling in the workplace and ambient environment.
