Detection of organic compounds in respiratory coal dust by high-resolution mass spectrometry.

NTIS: PB 213 949 :1-17
The investigation of organic compounds in respiratory coal dust by high-resolution mass spectrometry has shown that the organic compounds differ (1) with particle size, (2) with rank of coal, (3) in coals of same rank from different coal seams, and (4) in respirable mine dust and respirable coal dust (prepared) from the same mine. The eight respirable mine dusts studied are from coal seams in the Appalachian region where the incidence of coal workers' pneumoconiosis is relatively high. The molecular weights of the major organic components vary greatly among these respirable mine dusts; three show strong concentrations of polynuclear aromatic hydrocarbons.
