亚马逊盆地火灾排放的烟雾颗粒物对人类健康构成威胁。过去对这一威胁的研究主要集中在对整个国家的健康影响，或依赖住院数据来量化健康反应。这种分析没有包括对居住在靠近火灾的土著领地的人的影响，这些人往往得不到医疗护理，也可能不会去医院就诊。在这里，我们量化了生活在亚马逊盆地土著地区的人们因吸烟而过早死亡的情况。我们使用大气化学输送模式GEOS-Chem模拟了火灾和其他来源的PM2.5，并应用了最近更新的浓度剂量-反应函数。我们估计，从2014年到2019年，南美洲火灾产生的烟雾每年导致该大陆12000人过早死亡，其中约230%发生在土著土地上。换句话说，在整个南美洲，每年每10万人中有2人因接触烟雾而过早死亡，但在土著地区，每10万人中有4人过早死亡。玻利维亚和巴西是烟雾暴露的热点地区，这两个国家的土著地区的死亡人数分别为每10万人9人和12人。我们的分析表明，火灾产生的烟雾PM2.5对整个南美洲的人类健康都有不利影响，对生活在土著地区的人的影响不成比例。
Smoke particulate matter emitted by fires in the Amazon Basin poses a threat to human health. Past research on this threat has mainly focused on the health impacts on countries as a whole or has relied on hospital admission data to quantify the health response. Such analyses do not capture the impact on people living in Indigenous territories close to the fires and who often lack access to medical care and may not show up at hospitals. Here we quantify the premature mortality due to smoke exposure of people living in Indigenous territories across the Amazon Basin. We use the atmospheric chemistry transport model GEOS-Chem to simulate PM 2.5 from fires and other sources, and we apply a recently updated concentration dose-response function. We estimate that smoke from fires in South America accounted for∼ 12 000 premature deaths each year from 2014–2019 across the continent, with about∼ 230 of these deaths occurring in Indigenous lands. Put another way, smoke exposure accounts for 2 premature deaths per 100 000 people per year across South America, but 4 premature deaths per 100 000 people in the Indigenous territories. Bolivia and Brazil represent hotspots of smoke exposure and deaths in Indigenous territories in these countries are 9 and 12 per 100 000 people, respectively. Our analysis shows that smoke PM 2.5 from fires has a detrimental effect on human health across South America, with a disproportionate impact on people living in Indigenous territories.
