Element composition and source apportionment of atmospheric aerosols over the China Sea

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...

Source Apportionment of Sulfate and Nitrate over the Pearl River Delta Region in China

In this work, the Weather Research Forecast (WRF)–Sparse Matrix Operator Kernel Emission (SMOKE)–Comprehensive Air Quality Model with Extensions (CAMx) modeling system with particulate source apportionment technology (PSAT) module was used to study and analyze the source apportionment of sulfate and nitrate particulate matter in the Pearl River Delta region (PRD). The results show that superreg...

Characterization and source apportionment of atmospheric organic and elemental carbon during fall and winter of 2003 in Xi’an, China

Continuous measurements of atmospheric organic and elemental carbon (OC and EC) were taken during the high-pollution fall and winter seasons at Xi’an, Shaanxi Province, China from September 2003 through February 2004. Battery-powered mini-volume samplers collected PM2.5 samples daily and PM10 samples every third day. Samples were also obtained from the plumes of residential coal combustion, mot...
