摘要
An investigation is reported in which samples of airborne dusts were collected near heavily traveled highways and analyzed for rubber by pyrolysis gas chromatography. Dust samples obtained in truck traffic gave pyrolysis chromatograms markedly different from those obtained in passenger car traffic, and which correspond with those derived from known tire tread compounds. The distinction was based on the presence of styrene or dipentene in the pyrolyzates. Methods were developed for sampling atmospheric dusts and preparing small amounts in a form suitable for pyrolysis.
