大气细颗粒物（PM2.5）是世界上主要的环境健康风险因素。减少PM2.5疾病负担需要针对多个空间尺度的主要来源的具体策略。我们通过整合24个全球大气化学传输模型敏感性模拟，高分辨率卫星衍生的PM2.5暴露估计以及疾病特定浓度响应关系，对21个地区，204个国家和200个国家以下地区的特定部门和燃料对这种疾病负担的贡献进行了当代和全面的评估。在全球范围内，通过消除化石燃料燃烧（占PM2.5总负担的27.3%），2017年可避免105万（95%置信区间：0.74-1.36）人死亡，其中煤炭占一半以上。其他主要的全球来源包括住宅（74 [52 - 95]万例死亡; 19.2%）、工业（45 [32 - 58]万例死亡; 11.7%）和能源（39 [28 - 51]万例死亡; 10.2%）部门。我们的研究结果表明，具有较大人为贡献的地区通常具有最高的归因死亡率，这表明替代传统能源对健康有重大益处。大气细颗粒物（PM2.5）是许多地区最重要的环境健康风险因素之一。在本文中，作者对全球到次国家范围内的PM2.5排放源及其相关健康影响进行了评估，发现通过消除与化石燃料燃烧排放相关的PM2.5质量，2017年可避免超过100万人死亡。
Ambient fine particulate matter (PM2.5) is the world’s leading environmental health risk factor. Reducing the PM2.5 disease burden requires specific strategies that target dominant sources across multiple spatial scales. We provide a contemporary and comprehensive evaluation of sector- and fuel-specific contributions to this disease burden across 21 regions, 204 countries, and 200 sub-national areas by integrating 24 global atmospheric chemistry-transport model sensitivity simulations, high-resolution satellite-derived PM2.5 exposure estimates, and disease-specific concentration response relationships. Globally, 1.05 (95% Confidence Interval: 0.74–1.36) million deaths were avoidable in 2017 by eliminating fossil-fuel combustion (27.3% of the total PM2.5 burden), with coal contributing to over half. Other dominant global sources included residential (0.74 [0.52–0.95] million deaths; 19.2%), industrial (0.45 [0.32–0.58] million deaths; 11.7%), and energy (0.39 [0.28–0.51] million deaths; 10.2%) sectors. Our results show that regions with large anthropogenic contributions generally had the highest attributable deaths, suggesting substantial health benefits from replacing traditional energy sources. Ambient fine particulate matter (PM2.5) is one of the most important environmental health risk factors in many regions. Here, the authors present an assessment of PM2.5 emission sources and the related health impacts across global to sub-national scales and find that over 1 million deaths were avoidable in 2017 by eliminating PM2.5 mass associated with fossil fuel combustion emissions.
