摘　　要：针对具有多源大气污染的研究区域,计算了颗粒物、二氧化硫、氮氧化物和挥发性有机物的污染危害指数。多源大气污染危害性分析结果显示,挥发性有机物的危害最大,应作为最高优先级的防治对象;其次是氮氧化物,而颗粒物的危害相对较小,二氧化硫的整体危害最小。在颗粒物中,PM_(2.5)的防治优先级较高。对于氮氧化物,特别是四氧化二氮和五氧化二氮的危害较大,需要通过减少燃料燃烧、改进燃烧技术等手段实施防治。对于挥发性有机物中的苯、甲苯、二甲苯、丙烯腈、乙醇、正丙醇和正丁醇,需要通过减少使用、密闭存储等手段实施防治。The pollution hazard indices of particulate matter,sulfur dioxide,nitrogen oxides,and volatile organic compounds were calculated for the study area with multi-source air pollution.The results of the hazard analysis of multi-source air pollution show that volatile organic compounds pose the greatest harm and should be given the highest priority for prevention and control.Next is nitrogen oxides,while the harm of particulate matter is relatively small,and the overall harm of sulfur dioxide is the smallest.In particulate matter,PM_(2.5) has a higher prevention and control priority.The hazards of nitrogen oxides,especially nitrogen tetroxide and nitrogen pentoxide,are significant and require prevention and control measures such as reducing fuel combustion and improving combustion technology.For benzene,toluene,xylene,acrylonitrile,ethanol,n-propanol,and n-butanol in volatile organic compounds,prevention and control measures need to be implemented through reduced use,sealed storage,and other means.
