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.
在佛罗里达州，收获前燃烧甘蔗是一种常见的农业做法，这种做法会产生细颗粒物[空气动力学直径为 ()的颗粒物]，与更高的死亡率有关。
我们估计了 25 岁及以上人群因暴露于南佛罗里达州 20 个县的甘蔗燃烧而导致的过早死亡。
我们结合大气扩散模型、卫星和地面测量数据，量化了南佛罗里达州的 浓度和来自甘蔗火灾的 比例。根据这些浓度，通过使用与 相关的六种死因的文献中的健康影响函数，按人口普查区计算了归因于甘蔗火灾的 死亡率。置信区间（CI）是基于蒙特卡罗模拟得出的，该模拟传播了排放、扩散模型、健康影响函数和人口数据中的不确定性。
甘蔗燃烧产生的一次 量与佛罗里达州的机动车排放量相当。据估计，甘蔗燃烧产生的 对佛罗里达州甘蔗种植区（SGR）的死亡率贡献为每年每 10 万人 0.4 例（95%CI：0.3，1.6 例/每 10 万人）。这些估计表明，南佛罗里达州每年有 2.5 人死于与甘蔗燃烧有关的 （95%CI：1.2，6.1），其中 SGR 有 0.16 人（95%CI：0.09，0.6），棕榈滩县有 0.72 人（95%CI：0.17，2.2）。
据估计，甘蔗燃烧产生的 对南佛罗里达州的死亡率风险有贡献，特别是在 SGR。这与之前记录了甘蔗燃烧对空气质量影响但未量化死亡率的研究结果一致。这里没有量化的甘蔗燃烧的其他健康影响，包括加重哮喘和心血管问题等非致命性健康状况。如果不进行田间燃烧而收割甘蔗，可能会降低该地区的 和健康负担。https://doi.org/10.1289/EHP9957.
