Workers' exposure to hazardous substances must be held within acceptable limits. Therefore, airborne contaminant vapor and particles (including aerosols) in industrial atmospheres must be monitored. In the United States, the National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA) offer, for many such substances, specific recommendations on collecting (trapping) the contaminant on an adsorbent and/or filter, desorbing the collected analyte, analyzing the sample by gas or liquid chromatography, and quantifying the contaminant. Presented here is a general outline of the NIOSH and OSHA procedures, including formulas for calculating airborne concentrations of collected vaporous and particulate contaminants.
