Organic components of PM2.5 have drawn attention for the past decade as they have significant importance for human health, global and regional climate, and chemistry of the atmosphere. Beijing, as capital of China, has experienced serious air pollution problems due to its rapid economic growth and large population, which affect the surrounding areas via regional atmospheric transport. The aim of this study is to characterize atmospheric organic tracers, including PAHs, n-alkanes, hopanes, anhydrosugars, and cholesterol in order to investigate the sources of aerosols at Pinggu, a rural site close to Beijing.
