These included developing new sensors that can continuously monitor air contaminant concentrations or properties related to their concentration and utilizing computerized concentration mapping of workplace contaminants. Emerging workplace air monitoring technologies were discussed. These were primarily concerned with monitoring exposures to biological aerosols, such as those occurring in indoor and office environments, and in the biotechnology industry. In general, used as a basis for taking positive action in preventing, controlling, or abating health impacts from air pollution Ambient air quality standard means the concentration of an air pollutant which, in order to protect public health and/or public welfare, shall not be exceeded in the breathing zone, at any time. Other types of air monitoring were summarized. Performance criteria for evaluating estimates of worker exposures to workplace air contaminants were reviewed. Air monitoring was also used to evaluate the performance of control and process equipment. These included safety issues such as detecting explosive atmospheres, entry into confined spaces, and detecting hazardous gases and vapors that are immediately dangerous to life and health. Direct-reading instruments were also used to characterize peak and short-term exposures to hydrocarbon gases and vapors. Reasons for performing workplace air monitoring other than for measuring personal exposures were considered. Exposure assessments included full-shift and short-term personal breathing zone (PBZ) and area air sampling.

In the US, personal air sampling has been emphasized. Workplace air sampling consisted of obtaining samples of breathing zone (personal) and general air.

The US approach to air sampling in the workplace was discussed.
