Source apportionment of fine organic aerosols in Beijing
Fine particles (PM2.5, i.e., particles with an aerodynamic diameter of ≤2.5μm) were collected from the air in August 2005, August–September 2006, and January– February 2007, in Beijing, China. The chemical compositions of particulate organic matter in the ambient samples were quantified by gas chromatography/mass spectrometry. The dominant compounds identified in summertime were n-alkanoic acid...
متن کاملEvaluation of organic markers for chemical mass balance source apportionment at the Fresno Supersite
Sources of PM2.5 at the Fresno Supersite during high PM2.5 episodes occurring from 15 December 2000–3 February 2001 were estimated with the Chemical Mass Balance (CMB) receptor model. The ability of source profiles with organic markers to distinguish motor vehicle, residential wood combustion (RWC), and cooking emissions was evaluated with simulated data. Organics improved the distinction betwe...

متن کاملSource apportionment of submicron organic aerosols at an urban site by factor analytical modelling of aerosol mass spectra
Submicron ambient aerosol was characterized in summer 2005 at an urban background site in Zurich, Switzerland, during a three-week measurement campaign. Highly time-resolved samples of non-refractory aerosol components were analyzed with an Aerodyne aerosol mass spectrometer (AMS). Positive matrix factorization (PMF) was used for the first time for aerosol mass spectra to identify the main comp...
