项目摘要

Project summary Onshore expansion of Unconventional oil and gas development (UOGD) is considered an emerging environmental health issue due to its disproportional proliferation in rural U.S communities and the potential health impacts on 23 million nearby residents. However, two critical gaps in exposure assessment have restricted previous studies from achieving rigorous and actionable evidence regarding the acute health effects of UOGD construction stages. First, current exposure assessments were too coarse to accurately capture the short-term variability in exposure. Due to a lack of detailed construction records, investigators had to impute construction timelines for most wells based on questionable assumptions, which likely introduce misclassification. Second, none of prior large-scale observational studies has quantified exposure to specific UOGD-sourced pollutant. Investigators instead have developed various surrogates, which proxy residential exposure with functions of auxiliary factors (e.g., distance to UOGD wells). These exposure surrogates do not account for the different transports and fates of UOGD-sourced pollutants in ambient environment, thus cannot indicate specific exposure pathway(s). Furthermore, causal inference, which provide a rigorous adjustment for confounding, have not been widely used in estimating UOGD’s health effects. The objective of this proposal is to investigate the acute health effects of UOGD constructions based on improved satellite-based exposure assessment. In the K99 phase, I will take advantage of high-resolution images obtained by multiple recently launched satellites, including Sentinel-1s, Sentinel-2s, and Dove satellites to automatically detect the daily construction stage of UOGD wells (Aim 1). Multiple state-of-art causal inferential methods will be used to estimate the acute effects of each UOGD construction stage on the risk of cause-specific hospitalization in Medicare beneficiaries based on the new exposure assessment (Aim 2).In the R00 phase, I will develop and validate new exposure metrics based on the daily concentrations of air pollutants near UOGD wells, which are observed by Sentinel 5P (Aim3). Finally, I will explore the extent to which UOGD-related air pollutants mediate any effect of UOGD construction stages (Aim4). The expected outcomes are 1) an open-source software to detect UOGD-related activities from remote sensing images; 2) exposure metrics for UOGD-related air pollutants; 3) acute causal health effects of UOGD construction. The exposure data will be made public available to advance the field.

项目概要非常规石油和天然气开发（UOGD）的陆上扩张被认为是一种新兴的由于其在美国农村社区的不成比例扩散和潜在的环境健康问题对 2300 万附近居民的健康影响然而，暴露评估存在两个关键缺陷。限制了之前的研究获得关于急性健康影响的严格且可操作的证据首先，当前的暴露评估过于粗略，无法准确捕捉到。由于缺乏详细的施工记录，研究人员不得不估算暴露的短期变化。大多数油井的施工时间表基于有问题的假设，这可能会导致其次，之前的大规模观察研究都没有量化特定的暴露程度。相反，研究人员开发了各种替代物，用于替代住宅。具有辅助因素功能的暴露（例如，与 UOGD 井的距离）这些暴露替代项不具有影响。解释 UOGD 来源的污染物在周围环境中的不同迁移和归宿，因此无法表明具体的暴露途径此外，因果推断为以下提供了严格的调整。混杂因素尚未广泛用于估计 UOGD 的健康影响该提案的目的是。基于改进的卫星曝光研究 UOGD 结构对健康的急性影响在K99阶段，我将利用最近获得的多个高分辨率图像。发射卫星，包括Sentinel-1、Sentinel-2、Dove卫星，自动检测日常 UOGD 井的施工阶段（目标 1）将使用多种最先进的因果推理方法。评估每个 UOGD 建设阶段对特定原因住院风险的急性影响医疗保险受益人基于新的暴露评估（目标 2）。在 R00 阶段，我将制定和根据 UOGD 井附近空气污染物的每日浓度验证新的暴露指标，这些指标是最后，我将探讨与 UOGD 相关的空气污染物的介导程度。 UOGD 构建阶段（目标 4）的任何影响预期结果是 1) 一个开源软件从遥感图像中检测 UOGD 相关活动；2) UOGD 相关空气的暴露指标污染物；3）UOGD 施工对健康造成的急性影响暴露数据将予以公开。可用于推进该领域。
