Abstract
Literature concerning analysis of air contaminants has increased rapidly in recent years. EPA, Intersociety Committee, and ASTM reference methods are summarized. The validity of using data obtained with high volume samplers and gas absorption bubblers in sampling networks, using part-time operators, to determine base-line levels and air quality assurance is questioned. Dichotomous or size classification samplers for respirable particulates provide more accurate data to assess health effects. Described are: improved methods using particulate sulfates to determine the composition and effects of acid rain; new techniques for determining the composition of aerosol contaminants and measuring toxic gases, including coupled gas chromatography-mass spectrometry, X-ray fluorescence, and proton induced X-ray emission; and remote sensing methods involving correlation spectrometry, tunable lasers, and differential lidar.
