Vegetation fires across the tropics emit fine particulate matter (PM 2.5 ) to the atmosphere, degrading regional air quality and impacting human health. Extensive vegetation fires occur regularly across the Amazon basin, but there have been no detailed assessments of the impacts on air quality or human health. We used updated exposure-response relationships and a regional climate-chemistry model, evaluated against a comprehensive set of observational data, to provide the first in-depth assessment of the potential public health benefits due to fire prevention across the Amazon Basin. We focused on 2012, a year with emissions similar to the 11-year average (2008 to 2018). Vegetation fires contributed >80% of simulated dry season mean surface PM 2.5 in the western Amazon region particularly in Bolivia and Brazilian states of Rondônia, Acre, and Mato Grosso. We estimate that the prevention of vegetation fires would have averted 16 800 (95UI: 16 300–17 400) prem...

亚马逊森林和植被大火对空气质量和人类健康的影响很大

热带地区的植被大火向大气排放细颗粒物（PM 2.5），从而降低了区域空气质量并影响人类健康。整个亚马逊河流域经常发生大面积的植被大火，但尚未对空气质量或人类健康的影响进行详细评估。我们使用了更新的暴露-反应关系和区域气候化学模型，并根据一套全面的观察数据进行了评估，从而首次对整个亚马逊河流域的防火带来的潜在公共健康利益进行了深入评估。我们专注于2012年，这一年的排放量与11年平均值（2008年至2018年）相似。在亚马逊河西部地区，尤其是在玻利维亚和巴西朗多尼亚州，英亩，和马托·格罗索。我们估计，预防植被火灾将避免16800（95UI：16300–17400）保费...
