This report describes the development of a breadboard version of a CO/sub 2/ laser photoacoustic (LPA) detector. The CO/sub 2/ LPA technique was demonstrated to be capable of detecting, with high specificity, a variety of toxic compounds at low parts-per-billion (ppb) levels in multicomponent air samples. The technique can be used for monitoring trace levels of various hazardous compounds in ambient air samples. A key achievement during the program was determination of CO/sub 2/ laser absorption cross-section data for seven compounds of EPA concern that are volatile constituents of hazardous chemical waste. The data show that the LPA method can detect these compounds in ambient air at levels well below their most-stringent threshold limit values.
