High resolution mass spectroscopy has been found to be a useful means of characterizing the organic fraction of urban aerosols. Quantitative accuracy, however, was limited, particularly for compounds of low abundance. Some ambiguities were found in the assignment of origins of ions formed in the mass spectrometer. Compounds that were detected included phenols; aromatic carboxylic acids and, possibly, esters of these; and aliphatic dibasic acids. Evidence was found of several other difunctional compounds, including nitrate or nitrite species. Strong evidence was found for the presence in some urban aerosols of compounds reported by others as products of the oxidation of toluene in smog chamber reactions. Less evidence was found for products formed by the oxidation of terpenes. A few samples of automobile exhaust particulates were analyzed. The occurrence of benzoic acid and the benzoyl ion in mass spectra appear to be possible indicators of automotive contribution to the organic components. Results for a large number of compounds are provided for 88 samples of aerosols collected at sites located in the greater Los Angeles, Seattle, St. Louis, and Denver areas.
