Determination of organic compounds in airborne particulate matter by gas chromatography-mass spectrometry

Characterization of Atmospheric Particulate: Relationship between Chemical Composition, Size, and Emission Source

“…Gas chromatographymass spectrometry (GC-MS) combined with solvent extraction is a well-established technique, dating back to 1976, for the characterization of the organic components of PM. [8] However, this technique suffers from problems related to the solvent extraction procedure, which requires a relatively large amount of material which is not easy to obtain and may be responsible for the possible introduction of extraneous compounds. Furthermore, fractionation of the aerosols according to size, which is useful to obtain more precise information about the chemical nature of the particulate, introduces even more difficulties.…”

Measurements of selected dicarboxylic acids in marine cloud water

“…The role of organic compounds in aerosol chemistry has been investigated, in a somewhat desultory fashion, for many years (cf., Cautreels and Van Cauwenberghe, 1976;Grosjean et al, 1978;Graedel and Goldberg, 1983;Simoneit, 1986;Rivera-Carpio et al, 1996;etc. ), the end result of which has been a realization that organics constitute a very significant fraction of the atmospheric aerosol mass and play a large role in many atmospheric processes.…”

Coal Mine Workers' Pneumoconiosis (CWP):In VitroStudy of the Release of Organic Compounds from Coal Mine Dust in the Presence of Physiological Fluids

“…Phthalates in the heterocompound fractions of coal mine dust (Fig. 3c) are interpreted as ubiquitously occuring contaminations (Koch and Wagner, 1989;Cautreels and Van Cauwenberghe, 1976).…”
