生物质和煤炭的燃烧是中国家庭空气污染的主要来源，对中国人口的疾病总负担有很大贡献。为了解燃煤引起的肺癌高发区宣威和富源县30个村163名不吸烟的女户主的HAP暴露特征，对两个相邻的农村燃煤引起的肺癌高发区进行了暴露评估（一种烟煤，在健康评估中通常与无烟煤--该地区某些地区可用的无烟煤--相比较）。在每个家庭中连续两天收集个人和室内24小时PM2.5样本，大约三分之一的测量结果在第二个季节重新进行。宣威和抚远个人PM2.5浓度的总体几何平均值（GM）分别为166 [几何标准差（GSD）：2.0]和146（GSD：1.9）μg/m3，与室内PM2.5空气浓度[GM（GSD）：分别为162（2.1）和136（2.0）μg/m3]相似。个人PM2.5与室内PM2.5中度高度相关（斯皮尔曼r = 0.70，p < 0.0001）。燃烧木材或植物材料（烟草茎，玉米棒等）结果表明，燃煤污染物的PM2.5浓度最高（GM分别为289和225 μg/m3），其次是无烟煤（GM分别为148和115 μg/m3）。在所有燃料类型中，通风炉的PM2.5水平比不通风炉和火坑低34-80%。混合效应模型表明，燃料类型，通风，窗户数量，季节，每个炉子燃烧时间是与个人PM2.5暴露相关的主要因素。与无通风口的炉子和火坑相比，通风口的炉子中的PM2.5较低，这一点很有趣，因为它与该地区恶性和非恶性肺部疾病风险降低的观察结果相似。
The combustion of biomass and coal is the dominant source of household air pollution (HAP) in China, and contributes significantly to the total burden of disease in the Chinese population. To characterize HAP exposure related to solid fuel use and ventilation patterns, an exposure assessment study of 163 nonsmoking female heads of households enrolled from 30 villages was conducted in Xuanwei and Fuyuan, two neighboring rural counties with high incidence of lung cancer due to the burning of smoky coal (a bituminous coal, which in health evaluations is usually compared to smokeless coal—an anthracite coal available in some parts of the area). Personal and indoor 24-h PM2.5 samples were collected over two consecutive days in each household, with approximately one-third of measurements retaken in a second season. The overall geometric means (GM) of personal PM2.5 concentrations in Xuanwei and Fuyuan were 166 [Geometric Standard Deviation (GSD):2.0] and 146 (GSD:1.9) μg/m3, respectively, which were similar to the indoor PM2.5 air concentrations [GM(GSD):162 (2.1) and 136 (2.0) μg/m3, respectively]. Personal PM2.5 was moderately highly correlated with indoor PM2.5 (Spearman r = 0.70, p < 0.0001). Burning wood or plant materials (tobacco stems, corncobs etc.) resulted in the highest personal PM2.5 concentrations (GM:289 and 225 μg/m3, respectively), followed by smoky coal, and smokeless coal (GM:148 and 115 μg/m3, respectively). PM2.5 levels of vented stoves were 34–80% lower than unvented stoves and firepits across fuel types. Mixed effect models indicated that fuel type, ventilation, number of windows, season, and burning time per stove were the main factors related to personal PM2.5 exposure. Lower PM2.5 among vented stoves compared with unvented stoves and firepits is of interest as it parallels the observation of reduced risks of malignant and nonmalignant lung diseases in the region.
