Source tests were conducted to analyze and characterizediagnostic key tracers for emissions from burning ofcoals with various ranks. Ambient aerosol particulate matterwas also collected in three areas of China and abackground area in Corvallis, OR (U.S.) to confirm thepresence of tracers specific for coal smoke. The resultsshowed a series of aliphatic and aromatic hydrocarbons andphenolic compounds, including PAHs and hydroxy-PAHsas the major tracers, as well as a significant unresolvedcomplex mixture (UCM) of compounds. The tracers that werefound characteristic of coal combustion processesincluded hydroxy-PAHs and PAHs. Atmospheric ambientsamples from Beijing and Taiyuan, cities where coal is burnedin northern China, revealed that the hydroxy-PAH tracerswere present during the wintertime, but not in cities wherecoal is not commonly used (e.g., Guangzhou, SouthChina). Thus, the mass of hydroxy-PAHs can be apportionedto coal smoke and the source strength modeled bysumming the proportional contents of EC (elemental carbon),PAHs, UCM and alkanes with the hydroxy-PAHs.
