ABSTRACT A light weight and inexpensive sampling device to sample the respirable fraction of aerosols in a work environ- ment on a continuous basis is described. The device consists of a short length of capillary tubing having an internal diameter of about 1.3mm in a series with a somewhat longer length of capillary tubing having an internal diameter of about 0.5mm which acts as a collector or sampler and which is in turn connected to an aspirating device. The sampler tube may be wound on a spool which is so small that the entire device is button sized and may be conveniently worn on the lapel as a personal monitoring device. The trapped respirable aerosol particles may be washed out of the sampler periodically for counting and/or chemical analysis.
