The general types of particulate matter present in the industrial environment and sampling methods are discussed. Industrial particulates consist of dust, respirable dust, fume, mist, and fibers. The recent emphasis on personal sampling as opposed to area sampling has produced a trend to wear small battery operated samplers. The hi-vol sampler still has some application in areas where the level of contaminants is low and personal samplers cannot collect enough dust for accurate chemical analysis. Sampling the industrial environment for respirable mass concentrations of particulate material in the workers breathing zone is currently limited to coal and silica dust. Sampling for fume is basically the same as for dusts, only that the filters used in the cassettes must be so selected to collect and retain the smaller fume particles. Most mist sampling has been performed with liquid impingers which are difficult to use, however, when trying to collect breathing zone samples. Sampling for particulate fibers is a major challenge to the industrial hygienist. Fibers are not only difficult to assay from the analytical standpoint, but their aerodynamic particle size is not completely understood and consequently it has not been determined which size of fibers are the most harmful. Two new respirable mass samplers are being designed to collect more dust in a shorter time period so that peak dust concentrations can be measured in the working environment. (Air Pollut. Abstr.)
