Fires burning across the Amazon in the summer of 2019 attracted global attention for the widespread destruction of natural ecosystems and regional smoke production. Using a combination of satellite fire observations and atmospheric modeling, Nawaz and Henze (2020, https://doi.org.10.1029/2020GH000268) provide new evidence for the widespread regional public health consequences attributed to these fires. They find that approximately 10% of premature deaths in Brazil due to fine particulate matter (PM_2.5) are attributable to smoke pollution and highlight how fire locations play a critical role in determining downwind health impacts.

巴西大火如何影响空气污染和公共健康？

由于自然生态系统的广泛破坏和区域烟雾的产生，2019年夏季亚马逊熊熊燃烧的大火引起了全球关注。Nawaz和Henze（2020，https：//doi.org.10.1029/2020GH000268）将卫星火灾观测与大气建模相结合，为这些火灾造成的广泛区域公共卫生后果提供了新的证据。他们发现，巴西约有10％的细颗粒物（PM _2.5）造成的过早死亡可归因于烟雾污染，并突显了火灾发生地点如何在决定顺风对健康的影响方面发挥关键作用。
