High resolution mass spectrometry was applied as a direct, rapid method of analysis of the organic material associated with diesel exhaust particulates. Diesel fuels and respirable coal mine dusts were also surveyed. Data analysis of the spectrometric results enabled precise masses and molecular formulas of hundreds of organic components in each sample to be determined. The organic components were characterized by structural type and carbon number range. The mass spectral data of the samples were screened for indications of the presence of toxic compounds. Screening was effected by computer matching of experimental masses with toxic compound masses contained in a reference list of substances having low threshold limit values.
