Abstract:Abstract. Fine particulate matter (PM2.5) pollution is still one of China's most important environmental issues, especially in northern cities
during wintertime. In this study, intensive real-time measurement campaigns
were conducted in Xi'an, Shijiazhuang, and Beijing to investigate the
chemical characteristics and source contributions of PM2.5 and explore
the formation of heavy pollution for policy implications. The chemical
compositions of PM2.5 in the three cities were all dominated by organic
aerosol (OA)… Show more
