- Abstract
We chose a traffic intersection that were heavily polluted in Haidian District of Beijing as the representative monitoring point to collect of atmospheric particulate samples within four seasons, respectively, and analysis of the PM2.5 and PAHs levels and their contribution to haze in Beijing atmosphere. The results showed that the concentration of PM2.5 and seasonal characteristics of PAHs follow this order: winter> autumn> spring> summer in Haidian District of Beijing, and the composition of PAHs are mainly four and five membered ring derivatives. In addition, by using the ratio calculation method, it was concluded that the combustion contributes the most for PAHs in PM2.5 contamination in Beijing.
