许多发展中区域需要全面的、按空间分列的排放清单，以评估不同来源的相对影响，并制定可导致有效排放控制的缓解战略。本研究开发了一个1 km 2的非甲烷挥发性有机化合物（NMVOC）排放模型，用于1993年至2016年印度燃料木材，牛粪饼，城市固体废物（MSW），木炭，煤炭和液化石油气（LPG）的燃烧。输入数据选自一系列详细的燃料消耗调查和在对当地燃烧源进行全面研究期间测得的最近排放系数。对于2011年的人口普查，我们估计印度生物质和城市生活垃圾燃烧排放的NMVOCs约为13（5-47）Tg。其中约54%的排放来自住宅固体生物燃料燃烧，23%来自城市固体废物的露天燃烧，23%来自农田作物残留物燃烧，<1%来自烹饪用液化石油气。住宅燃烧的NMVOC排放量被证明是非常敏感的牛粪饼燃烧的量，这作为一个关键的污染源在印度-恒河平原。本研究的结果表明，需要多种缓解策略，在几个不同类别的燃烧源，以实现有效的NMVOC减排。
Comprehensive, spatially disaggregated emission inventories are required for many developing regions to evaluate the relative impacts of different sources and to develop mitigation strategies which can lead to effective emission controls. This study developed a 1 km2non-methane volatile organic compound (NMVOC) emission model for the combustion of fuel wood, cow dung cake, municipal solid waste (MSW), charcoal, coal and liquefied petroleum gas (LPG) in India from 1993 to 2016. Inputs were selected from a range of detailed fuel consumption surveys and recent emission factors measured during comprehensive studies of local burning sources. For the census year of 2011, we estimated around 13 (5–47) Tg of NMVOCs were emitted from biomass and MSW combustion in India. Around 54% of these emissions were from residential solid biofuel combustion, 23% from open burning of MSW, 23% from crop residue burning on fields and <1% from LPG for cooking. NMVOC emissions from residential combustion were shown to be highly sensitive to the amount of cow dung cake combusted and this acted as a key pollution source across the Indo-Gangetic Plain. The results of this study indicate that multiple mitigation strategies are required across several different categories of burning source to achieve effective NMVOC emission reduction.
