摘要： 为了研究大气中非甲烷有机化合物( NMOCs) 总体现状、组成特点和不同物种臭氧产生潜力, 以便在臭氧产生对 NMOCs 敏感的区域制定有效的臭氧控制政策, 对上海市区徐家汇从 2005年11月6 日到2007年8月10日进行了每日24 小时NMOCs 采样。数据分析表明, 上海市区 NMOCs 的日平均浓度没有明显的季节变化, 大约在 50nL/L, 主要由烷烃类、烯烃类和芳香烃类组成。反应活性和浓度水平都较高的芳香烃类对臭氧光化学产生的贡献占主导性地位。甲苯、二甲苯、乙基苯、丁烯和丙烯是臭氧产生潜力最大的几个物种。上海市区大气中的NMOCs以人为排放为主, 主要来自城市机动车尾气、建筑材料和有机溶剂的挥发以及南部金山化工区的排放。

Abstract: The study of general status of NMOCs, NMOCs composition and ozone formation potentials of various NMOCs species help better understand the ozone problem and make effective ozone abatement strategies in NMOCs-sensitive regime. Analysis of NMOCs 24-hours sampling from November 6, 2005 to August 8,2007 in urban Shanghai Xujiahui indicates that daily NMOCs display no apparent seasonal variation with average concentration of about 50 ppbv. The major components are alkanes, alkenes and aromatics. Due to their relatively high reactivities and concentrations, aromatics play a dominant role in contributing to ozone photochemical production. Toluene, xylene, ethylbenzene, butene and propene are found to be among the top list of ozone formation potentials. NMOCs in urban Shanghai are largely of anthropogenic origin. They are mainly from vehicular exhausts, evaporation of solvents and architectural materials and emissions from the petrochemical complex in the southern Jinshan District.

Key words: nonmethane organic compounds (NMOCs), ozone formation potential, Shanghai
