Short summary
The characteristics of n-alkanes and the contributions of various sources of PM2.5 in the atmosphere in Beijing were studied. There were marked seasonal and diurnal differences in the n-alkane concentrations (p<0.01). Particulate-bound n-alkanes were supplied by anthropogenic and biogenic sources; fossil fuel combustion was the dominant contributor. Vehicle exhausts strongly affect PM2.5 pollution. Controlling vehicle exhaust emissions is key to control n-alkane and PM2.5 pollution in Beijing.
