“…In comparison with nearby Delray Beach,

concentrations (PM that is

or less in aerodynamic diameter) in Belle Glade were similar outside of harvest season, but on average 50% higher during sugarcane harvest season ( Sevimoğlu and Rogge 2016 , 2015 ). Concentrations of airborne polycyclic aromatic hydrocarbons (PAH) and other chemical indicators of biomass burning were up to 15 times higher at Belle Glade during harvest than other times of the year ( Afshar-Mohajer et al. 2016 ; Sevimoğlu and Rogge 2016 , 2019 ).…”

Background: 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. Objectives: We estimated premature mortality associated with exposure to from sugarcane burning in people age 25 y and above for 20 counties in South Florida. Methods: 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. Results: 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). Discussion: 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

“…PAHs in the atmosphere are mainly released from human activities (Afshar-Mohajer et al, 2016;, and PAHs discharged into the air can be adsorbed on PM2.5, increasing the harm to human health. Therefore, it is of great significance to study the PAHs bound to PM2.5 during haze.…”
