Abstract
To measure ambient concentrations and individual exposure to potentially hazardous chlorinated organic compounds, analytical methodology using absorbentbased samplers (passive exposure devices) and gas chromatographic techniques were developed. The samplers selectively absorb and concentrate chlorinated organics and other organic compounds diffusing into the solid absorbent. Analysis is carried out by desorption of the trapped compounds by heating, separation by gas chromatography and detection using a Hall detector for the chlorinated organics. Sampling and analytical techniques were evaluated under laboratory conditions with low concentrations of gaseous compounds and optimized for detection and quantitation. The samplers and analytical techniques are capable of detecting subparts-per-billion concentrations of test compounds after one-half hour exposure.
