项目摘要

Abstract For over a year, residents of Bristol, Tennessee (TN) and Virginia (VA) have experienced significant exposure to landfill emissions including volatile organic compounds (VOCs) such as benzene, toluene, and hydrogen sulfide. Ambient levels of these air toxics have been measured by the EPA and the Virginia Department of Environmental Quality. Based on the concentrations found during these sampling events, a Plan of Action was released on July 6, 2022 to begin incremental steps towards mitigating the air toxics emanating from the landfill. This Plan of Action presents a critical opportunity to measure the impact of this environmental policy to improve air quality and reduce odors. Since October 2021, Haynes (PI) has been developing a community- academic research partnership with Bristol residents to identify research strategies to identify their indoor and outdoor exposures and potential health impacts. The residents have reported their experiences as “an endless nightmare,” with “non-stop odor that stays in the house,” and “its hard to breathe.” Given our partnership with the City Manager and community residents, we are poised to evaluate the impacts of an environmental policy to reduce air toxics and odors and evaluate the potential long-term health consequences related to these exposures. We propose these highly time-sensitive specific aims: Aim 1: Characterize indoor and outdoor concentrations of VOCs, including benzene and hydrogen sulfide in and around homes of Bristol, VA/TN residents prior to the implementation of the mitigation action plan. Aim 2: Characterize indoor and outdoor concentrations of VOCs and hydrogen sulfide in and around homes of Bristol, VA/TN residents after each stage of the mitigation action plan in order to determine the impact of the various strategies to mitigate exposures. Aim 3: Evaluate the impact of the landfill and the mitigation plan on odor detection, quality of life, and stress of residents. This time-sensitive research is critical to inform future landfill mitigation efforts as numerous communities across the country face challenges associated with municipal solid waste facilities.

抽象的一年多来，布里斯托尔、田纳西州 (TN) 和弗吉尼亚州 (VA) 的居民经历了严重的暴露垃圾填埋场排放物，包括苯、甲苯和氢气等挥发性有机化合物 (VOC) EPA 和弗吉尼亚州部门已测量了这些空气有毒物质的环境水平。环境质量。根据这些采样过程中发现的浓度，制定了一项行动计划。于 2022 年 7 月 6 日发布，开始采取渐进措施减轻空气中有毒物质的排放该行动计划提供了一个重要的机会来衡量该环境政策对垃圾填埋场的影响。自 2021 年 10 月以来，Haynes (PI) 一直在开发一个社区—— 与布里斯托尔居民建立学术研究伙伴关系，以确定研究策略，以确定他们的室内和居民们将他们的经历描述为“无尽的户外暴露和潜在的健康影响”。噩梦”，“屋子里持续不断的气味”，“考虑到我们的合作伙伴关系，呼吸困难”。城市管理者和社区居民，我们准备评估环境影响减少空气有毒物质和气味并评估与这些相关的潜在长期健康后果的政策我们提出这些对时间高度敏感的具体目标：目标 1：描述室内和室外的特征。弗吉尼亚州/田纳西州布里斯托尔住宅及其周围的 VOC 浓度，包括苯和硫化氢目标 2：描述室内和室外的特征。布里斯托尔、弗吉尼亚州/田纳西州居民家中及周围的挥发性有机化合物和硫化氢浓度缓解行动计划的阶段，以确定各种缓解策略的影响目标 3：评估垃圾填埋场和缓解计划对气味检测、生活质量、这项对时间敏感的研究对于为未来的垃圾填埋场缓解工作提供信息至关重要。全国许多社区面临着与城市固体废物处理设施相关的挑战。
