| Zusammenfassung |
| Controlled bench scale pulverized coal combustion studies were performed,
demonstrating that inorganic particles play a critical role as carriers of
organic species. Two commonly-used aerosol mass spectrometry techniques were
applied to characterize fine particle formation during coal combustion. It
was found that the organic species in coal combustion aerosols have mass
spectra similar to those generated by biomass combustion. Ambient
measurements in Shanghai, China confirm the presence of these species in
approximately 29–38% of the sampled particles. With the absence of
major biomass sources in the Shanghai area, it is suggested that coal
combustion may be the main source of these particles. This work indicates
there is a significant potential for incorrect apportionment of coal
combustion particles to biomass burning sources using widely adopted mass
spectrometry techniques. |
