5, and CO, there are databases from studies in which selected human volunteers were exposed to the pollutant in purified lab air for specific time intervals ranging from minutes to eight hours. Most studies involve a series of such exposures in random order, in which there are exposures at one or more concentrations as well as a sham exposure to purified air. Many of them involved prescribed periods and intensities of exercise during the exposure interval. The most commonly measured pulmonary effects were changes in forced expiratory flow rates and volumes and/or changes in airway resistance and compliance.

Many of them involved prescribed periods and intensities of exercise during the exposure interval. The most commonly measured pulmonary effects were changes in forced expiratory flow rates and volumes and/or changes in airway resistance and compliance. A broad variety of other pulmonary function tests require the inhalation of special breathing mixtures and hence more elaborate controls and protocol reviews. 3% CO to determine diffusing capacity at the alveolo-capillary membrane (Crapo, 1986); and (3) a low density inert gas, such as helium (He), or a high density gas, such as sulfur hexafluoride (SF6), to measure inhomogeneities in flow distribution (Scott and Van Liew, 1983).

Air concentrations measured at fixed (area) sites in industry may be CHARACTERIZATION OF HEALTH 23 much lower than those occurring in the breathing zone of workers close to the contaminant sources. Air concentrations at fixed (generally elevated) community air-sampling sites can be either much higher or much lower than those at street level and indoors as a result of strong gradients in source and sink strengths in indoor and outdoor air.
