Global solid biofuel stove emissions strongly impact air quality, climate change, and human health. However, investigations of the impacts of global solid biofuel stove emissions on human health associated with PM (particulate matter with aerodynamic diameter ≤2.5 μm) and ozone (O) are limited. Here, we quantify the impacts of global solid biofuel stove emissions on ambient PM and O air quality and the associated human health effects for the year 2010, using the Community Atmosphere Model coupled with Chemistry version 5.3. Annual mean surface PM concentrations from global solid biofuel stove emissions averaged over 2006-2010 are up to 23.1 μg m, with large impacts found over China, India, sub-Saharan Africa, and eastern and central Europe. For surface O impacts, we find that global solid biofuel stove emissions lead to increases in surface O concentrations by up to 5.7 ppbv for China, India, and sub-Saharan Africa, and negligible impacts or reductions of up to 0.5 ppbv for the US, Europe, and parts of South America. Global solid biofuel stove emissions for the year 2010 contribute to 382,000 [95% confidence interval (95CI): 349,000-409,000] annual premature deaths associated with PM and O exposure, with the corresponding years of life lost as 8.10 million years (95CI: 7.38-8.70 million years). Our study highlights air quality and human health benefits of mitigating emissions from the global solid biofuel stove sector, especially over populous regions of low-income and middle-income countries, through promoting clean household energy programs for the residential energy supply.
全球固体生物燃料炉灶排放对空气质量、气候变化和人类健康有重大影响。然而，关于全球固体生物燃料炉灶排放对与细颗粒物（空气动力学直径≤2.5μm的颗粒物）和臭氧（O₃）相关的人类健康影响的研究有限。在此，我们使用耦合化学版本5.3的社区大气模型，量化了2010年全球固体生物燃料炉灶排放对环境细颗粒物和臭氧空气质量的影响以及相关的人类健康效应。2006 - 2010年期间全球固体生物燃料炉灶排放的年平均地表细颗粒物浓度平均高达23.1μg/m³，在中国、印度、撒哈拉以南非洲以及东欧和中欧地区发现了较大影响。对于地表臭氧影响，我们发现全球固体生物燃料炉灶排放导致中国、印度和撒哈拉以南非洲的地表臭氧浓度增加高达5.7ppbv，而在美国、欧洲和南美洲部分地区影响可忽略不计或减少高达0.5ppbv。2010年全球固体生物燃料炉灶排放导致与细颗粒物和臭氧暴露相关的每年38.2万例（95%置信区间：34.9万 - 40.9万例）过早死亡，相应的生命损失年数为810万年（95%置信区间：738万 - 870万年）。我们的研究强调了通过推广用于住宅能源供应的清洁家庭能源计划，减少全球固体生物燃料炉灶部门排放对空气质量和人类健康的益处，特别是在低收入和中等收入国家的人口密集地区。
