收获前焚烧甘蔗在佛罗里达州是一种常见的农业做法，它会产生与较高死亡率相关的细颗粒物[具有空气动力学直径的颗粒物(PM)]。我们估计了南佛罗里达州20个县25岁及以上人群中与甘蔗焚烧暴露相关的过早死亡率。我们结合了来自大气扩散模型、卫星和地面测量的信息，以量化南佛罗里达州的浓度和甘蔗火灾产生的二氧化碳比例。根据这些浓度，可归因于甘蔗火灾的估计死亡率由人口普查区使用从文献中得出的与以下六种死因相关的健康影响函数来计算。可信区间(CI)是基于蒙特卡罗模拟提供的，该模拟传播排放、扩散模型、健康影响函数和人口数据中的不确定性。甘蔗大火排放的初级气体数量与佛罗里达州的机动车相似。据估计，甘蔗火灾导致佛罗里达甘蔗种植区(SGR)的死亡率每年每10万人死亡0.4人(95%可信区间：0.3，每10万人1.6人)。这些估计表明，南佛罗里达州每年有2.5人死于甘蔗火灾(95%CI：1.2，6.1)，其中SGR地区为0.16人(95%CI：0.09，0.6)，棕榈滩县为0.72人(95%CI：0.17，2.2)。据估计，甘蔗火灾会导致整个南佛罗里达州的死亡风险，特别是在SGR地区。这与先前的研究一致，这些研究记录了甘蔗火灾对空气质量的影响，但没有量化死亡率。甘蔗火灾对健康的其他影响没有在这里量化，包括加剧哮喘和心血管问题等非致命性健康问题。在不焚烧田地的情况下收获甘蔗可能会减轻该地区的健康负担。Https://doi.org/10.1289/EHP9957
Preharvest burning of sugarcane is a common agricultural practice in Florida, which produces fine particulate matter [particulate matter (PM) with aerodynamic diameter ()] that is associated with higher mortality. We estimated premature mortality associated with exposure to from sugarcane burning in people age 25 y and above for 20 counties in South Florida. We combined information from an atmospheric dispersion model, satellites, and surface measurements to quantify concentrations in South Florida and the fraction of from sugarcane fires. From these concentrations, estimated mortalities attributable to from sugarcane fires were calculated by census tract using health impact functions derived from literature for six causes of death linked to . Confidence intervals (CI) are provided based on Monte Carlo simulations that propagate uncertainty in the emissions, dispersion model, health impact functions, and demographic data. Sugarcane fires emitted an amount of primary similar to that of motor vehicles in Florida. from sugarcane fires is estimated to contribute to mortality rates within the Florida Sugarcane Growing Region (SGR) by 0.4 death per 100,000 people per year (95% CI: 0.3, 1.6 per 100,000). These estimates imply 2.5 deaths per year across South Florida were associated with from sugarcane fires (95% CI: 1.2, 6.1), with 0.16 in the SGR (95% CI: 0.09, 0.6) and 0.72 in Palm Beach County (95% CI: 0.17, 2.2). from sugarcane fires was estimated to contribute to mortality risk across South Florida, particularly in the SGR. This is consistent with prior studies that documented impacts of sugarcane fire on air quality but did not quantify mortality. Additional health impacts of sugarcane fires, which were not quantified here, include exacerbating nonfatal health conditions such as asthma and cardiovascular problems. Harvesting sugarcane without field burning would likely reduce and health burdens in this region. https://doi.org/10.1289/EHP9957
