摘要 | To evaluate the influence of the implementation of emission reduction measures on air quality during the 2015 China Victory Day Parade, the characteristics of organic aerosols in particulate matter with a diameter less than 2.5 gm (PM2.5) were analyzed from 11 August to 10 September 2015 in Beijing, China. The average concentration of PM2.5 decreased by 64% during the 2015 China Victory Day Parade compared with that before the event. Local emissions were the main PM2.5 sources during the 2015 China Victory Day Parade; cooking and traffic emission were two significant contributors. During the 2015 China Victory Day Parade, the average concentrations of levoglucosan and dehydroabietic acid decreased by 31% and 12%, respectively, indicating the significant effects of regional air pollution controls on air quality. 17 alpha(H), 21 beta(H)-30-Norhopane and 17 alpha(H), 21 beta(H)-hopane concentrations decreased continuously throughout the entire study period, suggesting the significant effect of the "odd-even" traffic restrictions implemented. Similarly, o-phthalic acid, succinic acid, and 2,3-dihydroxy-4-oxopentanoic acid (DPA) concentrations also significantly decreased during the Parade, with reductions of 63, 50, and 61%, respectively, compared with before the event. Photochemical oxidation played an important role in the formation of o-phthalic acid, while the formation of DPA was influenced by both photochemical oxidation and liquid-phase chemical reactions. The lung cancer risk, caused by inhalation exposure to polycyclic aromatic hydrocarbons, to the exposed populations decreased by 40% during the 2015 China Victory Day Parade, the enhanced control measures implemented during Parade Blue would also have positive influence on the human health. |
