Many researchers are concerned that municipal solid waste (MSW) threatens public health, causing them to increasingly focus on odor pollution. In this study, the odor nuisance and health risk impacts of landfill surface gas on eight sensitive receptors were assessed. The emission rates of odor and 145 volatile organic compounds (VOCs) were acquired by considering various landfilling operations, including high-density polyethylene (HDPE) membrane removal (MR), landfill tipping area (TA), temporary HDPE membrane cover (MC), top of the HDPE membrane (LM) and dumping platform (DP). Furthermore, differences in landfill surface geometry, such as emission height and source area, and variations in residential living floors were considered in odor assessment with the air dispersion model. Based on these uncertain factors, normal-, medial-, and worst-case scenarios were defined to elucidate the odor nuisance effect and health risk impact. Four of the eight sensitive receptors, which were 2.6 km away from the landfill surface, basically experienced odor nuisance and health risk impacts. Dichloromethane exerted an indelible and crucial impact on body health based on a comprehensive investigation of aromatics, halocarbons, and other chemicals. The odor nuisance and health risk impacts were notable near the landfill, and the local environment was remarkably damaged.
许多研究人员担心城市固体废物（MSW）会威胁公众健康，这促使他们越来越关注恶臭污染。在这项研究中，评估了垃圾填埋场表面气体对 8 个敏感受体的恶臭扰民和健康风险影响。通过考虑各种填埋作业，包括高密度聚乙烯（HDPE）膜去除（MR）、垃圾填埋场倾卸区（TA）、临时 HDPE 膜覆盖（MC）、HDPE 膜顶部（LM）和倾卸平台（DP），获得了恶臭和 145 种挥发性有机化合物（VOCs）的排放率。此外，在使用空气扩散模型进行恶臭评估时，还考虑了垃圾填埋场表面几何形状的差异，如排放高度和源面积，以及居民居住楼层的变化。基于这些不确定因素，定义了正常、中值和最差情况场景，以阐明恶臭扰民效应和健康风险影响。距离垃圾填埋场表面 2.6 公里的 8 个敏感受体中的 4 个基本经历了恶臭扰民和健康风险影响。基于对芳烃、卤代烃和其他化学品的综合调查，二氯甲烷对身体健康产生了不可磨灭和关键的影响。在垃圾填埋场附近，恶臭扰民和健康风险影响显著，当地环境受到严重破坏。
