【摘要】：以我国人为源挥发性有机物(VOCs)为研究对象,使用具有代表性的VOCs总量排放清单、各污染源成分谱及物种最大增量反应活性值(MIR),建立了2010年我国人为源VOCs基于臭氧生成潜势(OFP)的反应性排放清单.结果表明,2010年我国人为源挥发性有机物总OFP为84 187.61 kt,其中,烷烃6 882.53 kt,烯炔烃41 496.92 kt,芳香烃32 945.32 kt,卤代烃161.45kt,含氧有机化合物2 701.40 kt.OFP贡献前10种物种分别为丙烯、乙烯、间/对-二甲苯、甲苯、1-丁烯、邻-二甲苯、1,2,4-三甲苯、1,3-丁二烯、间-乙基甲苯和乙苯,占人为源总OFP的63.95%,仅占VOCs排放总量的31.84%.人为源三大污染源中,工业源贡献了49.29%的OFP,为最大贡献源,其次是交通源28.31%和农业源22.40%.建筑装饰、石油炼制、储存与运输、机械设备制造、交通设备制造和包装印刷为工业OFP主要贡献源;轻型载客汽车、重型载客汽车及摩托车为交通源OFP污染控制的重点;生物质燃烧两类子源均为农业源OFP重点控制对象.山东、江苏、广东、浙江和河南是我国人为源OFP贡献最大的省份,占人为源总OFP的39.65%.该反应性清单的建立,对我国基于反应性臭氧(O3)控制对策的制定具有重要意义.
[Abstract]:Taking volatile organic compounds (VOCs) as the research object, the representative total emission inventory of VOCs was used. The composition spectrum of each pollution source and the maximum incremental activity value of species (MIRN) were used to establish the reactivity emission inventory of China's anthropogenic VOCs in 2010 based on ozonation potential (OFP). The results showed that the total OFP of human volatile organic compounds in China in 2010 was 84 187.61 kt. among them, alkanes 6 882.53 kt, alkenes 41 496.92 kt, aromatic hydrocarbons 32 945.32 kt, halogenated hydrocarbons 161.45 kt, oxygenated organic compounds 2 701.40 kt.OFP contributed the top 10 species to propylene and ethylene, respectively. M-xylene 1-butene, o-xylene 1-butadiene, m-ethyltoluene and ethylbenzene account for 63.95% of total anthropogenic OFP, and only 31.84% of total VOCs emission. Of the three major sources of anthropogenic sources, industrial sources contributed 49.29% of OFPs, followed by traffic sources 28.31% and agricultural sources 22.40%. Building decoration, petroleum refining, storage and transportation, machinery and equipment manufacturing, transportation equipment manufacturing and packaging and printing are the main contribution sources of industrial OFP, light passenger vehicles, heavy duty passenger vehicles and motorcycles are the key points of OFP pollution control. Two kinds of sub-sources of biomass combustion are the key control objects of agricultural source OFP. Shandong, Jiangsu, Guangdong, Zhejiang and Henan are the provinces with the largest contribution to anthropogenic OFP, accounting for 39.65% of total anthropogenic OFP. The establishment of the reactivity list is of great significance to the formulation of control countermeasures based on reactive ozone O _ 3 in China.
