Household fuel combustion, especially using solid combustibles (biomass and fossil fuels), for cooking and other activities produces emissions that contribute to concentrations of indoor as well as outdoor air pollutants such as particulate matter with diameter smaller than 2.5 μm (PM) that deteriorate health and likely affect life expectancy (LEX). This study investigates the impact of PM from household combustion on LEX considering several covariates while controlling for ambient PM generated by other sectors. The generalized method of moments (GMM) model and the panel cointegration model were applied to a dataset of 43 Sub-Saharan Africa (SSA) countries over the time period of 1995-2010. Both approaches provide similar results indicating that household PM is significantly and negatively associated with higher aggregate LEX in the long-run, and, to a greater degree for female's. Also, among the control variables, PM from the transport sector has a greater influence on male's LEX. Thus, efforts should be combined to reduce household PM since lower levels are associated with increased LEX.
家庭燃料燃烧，特别是使用固体燃料（生物质和化石燃料）进行烹饪和其他活动，会产生排放物，导致室内和室外空气污染物浓度升高，例如直径小于 2.5μm 的颗粒物 (PM)，这些污染物会损害健康并可能影响预期寿命 (LEX)。本研究考虑了几个协变量，在控制其他部门产生的环境 PM 的情况下，调查了家庭燃烧产生的 PM 对 LEX 的影响。广义矩法 (GMM) 模型和面板协整模型被应用于 1995-2010 年期间 43 个撒哈拉以南非洲 (SSA) 国家的数据集。这两种方法都提供了相似的结果，表明家庭 PM 与长期内更高的总 LEX 显著负相关，并且对女性的影响更大。此外，在控制变量中，交通部门的 PM 对男性 LEX 的影响更大。因此，应共同努力降低家庭 PM，因为较低的水平与 LEX 的提高有关。
