摘    要:通过调研天津市工、农业生产和居民生活的统计资料,研究分析文献报道的各种污染源排放因子,计算出天津市各行业、各区县NOx、SO2、NMVOC、CO、NH3、PM10、PM2.5等污染物的排放量,发展了天津市2003年排放源清单.结果显示,天津市2003年各类污染物质的排放量NOx为1.77×105t,SO2为2.59 ×105t,NMVOC为2.24×105t,CO为1.33×106t,NH3为7.40×104t,PM10为2.52×105t,PM2.5为1.10×105t.从排放源的行业分布来看,燃煤源、汽车移动源、秸秆燃烧源是天津市大气污染物的重要排放源,燃煤源对各污染物的贡献分别为NOx46%,SO284%,NMVOC 1%,CO 58%,PM1018%,PM2.5 24%.火电、水泥、钢铁、炼焦、原油加工等行业依然是重要的工业污染排放源,火电对SO2的贡献为13%,钢铁对SO2的贡献为24%,对CO的贡献为30%.2003年天津市区对NO,、S02、NMVOC、CO等污染物的贡献均高于其它区县,对PM10、PM2.5的贡献也很高;塘沽区对NOx、SO2、NMVOC、CO等污染物的贡献很大,蓟县、武清区、宝坻区对NH3、PM10、PM2.5的贡献很大.

关 键 词:排放源清单  排放因子  空气污染  天津

Abstract:The amounts of several air pollutants emitted in each district and county of Tianjin in 2003 were calculated by investigating the statistical data of Tianjin industry, agriculture and residential life and analyzing every air pollutant emission factors in the literature. An emission inventory of NOx, SO2, NMVOC, CO, NH3, PM10 and PM2.5 for Tianjin is developed. According to this inventory, the total amount of pollutants emitted in the year of 2003 are NOx: 1.77×105 ton, SO2: 2.59×105 ton, NMVOC: 2.24×105 ton, CO: 1.33×106 ton, NH3: 7.40×104 ton, PM10: 2.52×105 ton, and PM2.5: 1.10×105 ton. For source attribution, coal combustion, automobile exhaust and crop burning are the most important emission sources in Tianjin. The contribution of coal combustion to the totals is 46% for NOx, 84% for SO2, 1% for NMVOC, 58% for CO, 18% for PM10, and 24% for PM2.5. Power stations, cement production, steel production, coking plants and oil refineries are also important industrial pollution sources. Specifically, power stations contribute 13% of the total SO2, while iron and steel production contributes 24% of the total SO2 and 30% of the total CO. The urban area contributes more to NOx, SO2, NMVOC and CO, as well as to PM10 and PM2.5, than the other areas in Tianjin. The Tanggu district has very large emission sources of NOx, SO2, NMVOC and CO, and the Jixian, Wuqing and Baodi districts have large emission sources of NH3, PM10 and PM2.5.
Keywords:emission inventory  emission factor  air pollution  Tianjin
