在发展中国家，固体燃料是各种国内活动的主要一次能源来源。迄今为止，国家首都地区的无机微量气体排放清单是使用默认排放系数或特定国家的排放系数编制的。本文首次报道了在实验室用稀释室测定的NCT贫民窟和农村地区生活燃料中无机痕量气体(SO2、NO、NO2、CO、CO2和CH4)排放因子的空间变化。在675个贫民窟群和146个农村村庄中的149个NCT地点收集了147个居住燃料样本，包括薪材、粪饼、作物残留物、煤炭等。SO2(0.02 ± 0.01~0.04 ± 0.01 mg/kg−1)、CH4(0.1~0.34 mg/kg−1)、NO2(0.01~0.02 mg/kg−1)的EF(S)低于CO(3.55 ± 1.72~6.07 ± 1.53 mg/kg−1)和二氧化碳(0~129.45 ± 46.94 mg/kg−1)。北部和西北部地区是CH4、NO和NO2排放的热区，南部和北部地区是CO2排放的热区。这些全市范围的无机微量气体排放清单(0.05° × 0.05°)是根据实验室确定的EFS和最近调查信息确定的现有消费数据编制的。在生活固体燃料中，燃料木和粪饼是NCT中无机痕量气体的两个主要贡献者。
In developing nations, solid residential fuels are the major sources of primary energy for various domestic activities. To date, the emission inventory of inorganic trace gases over National Capital Territory (NCT) was prepared using either default or country-specific emission factors. In this paper, we report (for the first time) the spatial variation of emission factors (EFs) of inorganic trace gases (SO2, NO, NO2, CO, CO2, and CH4) from the residential fuels used in slums and rural areas of NCT determined using dilution chamber in the laboratory. 147 residential fuel samples, including fuelwood, dung cake, crop residues, coal, etc., were collected at 149 NCT locations out of 675 slum clusters and 146 rural villages. The range of EF(s) of SO2(0.02 ± 0.01 to 0.04 ± 0.01 g kg−1), CH4(0.10 to 0.34 g kg−1), NO2(0.01 to 0.02 g kg−1) is lower than the CO (3.55 ± 1.72 to 6.07 ± 1.53 g kg−1) and CO2(0 to 129.45 ± 46.94 g kg−1). The north and north west districts of NCT are emission hotspots for CH4, NO, and NO2emissions, whereas, the southern and northern areas of NCT are for CO2. These citywide emission inventories (0.05° × 0.05°) of inorganic trace gases are prepared using laboratory-determined EFs and available consumption data determined by recent survey information. Among solid residential fuels, fuel wood, and dung cake are two major contributors to inorganic trace gases in NCT.
