家用固体燃料燃烧是有机化合物以气相和气溶胶相排放到大气中的主要来源;然而，目前对气体-颗粒分配和这些排放物的反应性驱动因素的理解存在很大的不确定性。这项研究开发了全面的，模型准备的有机排放概况国内固体燃料燃烧源收集来自印度德里。它还审查了负责二次有机气溶胶（SOA）的生产潜力和羟基自由基（OH）的反应，这些排放的有机物种。这些曲线涵盖了整个挥发性范围，包括非甲烷挥发性有机化合物（NMVOCs，有效饱和浓度，C* = 3 × 106至1011 μg m−3），中等挥发性有机化合物（IVOCs，C* = 300至3 × 106 μg m−3），半挥发性有机化合物（SVOC，C* = 0.3-300 μg m−3）以及低挥发性和极低挥发性有机化合物（L/ELVOC，其中LVOC C* ≤ 0.3 μg m−3）。该配置文件预测，IVOCs将大大有助于SOA的生产和燃烧的燃料木材和木炭释放一些最小比例的SVOCs。开发了一个模型来检查从燃烧排放物产生的SOA，该模型估计酚类化合物将贡献SOA的10-70%。呋喃类化合物是最重要的活性物质，占OH活性的9-48%和SOA的9-58%。不同的燃烧源也进行了比较，从燃料木材，农作物残留物，牛粪饼和城市固体废物（MSW）燃烧的排放量被证明是30，90，120和230倍以上的OH自由基比液化石油气（LPG）燃料的排放量。这项研究还估计，在可比的燃烧条件下，牛粪饼燃烧产生的SOA是燃料木材的3-4倍，城市生活垃圾燃烧产生的SOA是燃料木材的6-7倍。这项研究的结果表明，在德里的家用固体燃料源的燃烧排放有可能显着降低当地和区域的空气质量。因此，需要更有效的缓解战略，以限制固体燃料燃烧对印度等国家人类健康的影响。
Domestic solid fuel combustion is a major source of organic compounds to the atmosphere in gas and aerosol phases; however, large uncertainties exist in the current understanding of the gas-to-particle partitioning and the drivers of the reactivity of these emissions. This study developed comprehensive, model-ready organic emission profiles for domestic solid fuel combustion sources collected from Delhi, India. It also examined the organic species responsible for secondary organic aerosol (SOA) production potential and hydroxyl radical (OH) reactivity of these emissions. The profiles spanned the entire volatility range, including non-methane volatile organic compounds (NMVOCs, effective saturation concentration, C* = 3 × 106 to 1011 μg m−3), intermediate-volatility organic compounds (IVOCs, C* = 300 to 3 × 106 μg m−3), semi-volatile organic compounds (SVOCs, C* = 0.3–300 μg m−3) as well as low- and extremely low-volatility organic compounds (L/ELVOCs, where LVOC C* ≤ 0.3 μg m−3). The profiles predicted that IVOCs would contribute significantly to SOA production and that the combustion of fuel wood and charcoal released some of the smallest proportions of SVOCs. A model was developed to examine SOA production from burning emissions which estimated that phenolics would contribute 10–70% of the SOA. Furanics were the most important reactive species, contributing 9–48% of the OH reactivity and 9–58% of the SOA. Different combustion sources were also compared, with emissions from fuel wood, crop residue, cow dung cake and municipal solid waste (MSW) burning shown to be 30, 90, 120 and 230 times more reactive with the OH radical than emissions from liquefied petroleum gas (LPG) fuel. This study also estimated 3–4 times more SOA from cow dung cake combustion and 6–7 more from MSW combustion than fuel wood under comparable combustion conditions. The results of this study suggest that emissions from the combustion of domestic solid fuel sources in Delhi have the potential to significantly degrade local and regional air quality. As a result, more effective mitigation strategies are required to limit the impacts of solid fuel combustion on human health in countries like India.
