项目摘要
On February 3rd, 2023, a freight train derailment occurred in East Palestine in the State of Ohio. Following the train derailment, various hazardous chemicals, including butyl acrylate (BA), vinyl chloride (VC), and combustion by-products (e.g., polycyclic aromatic hydrocarbons) from a ‘controlled burn’ of the remaining VC and BA in the train cars, were released into nearby soils, sediments, groundwater aquifer, and waterways including the Ohio River which serves a source of drinking water for more than 5 million people. As of May 29, 2023, EPA and Norfolk Southern continue to 1) conduct air monitoring onsite and in the surrounding communities and 2) clean up the derailment site by excavating/disposing of contaminated soils and collecting/removing contaminated wastewater. This RAPID project will test the hypothesis that in contaminant-impacted areas, microbial communities will show measurable responses to the release of toxins, and that these responses could inform about contaminant degradation/detoxification processes and natural attenuation potential. To test this hypothesis, the Principal Investigator (PI) and co-investigators from the University of Tennessee (UT) Knoxville and the environmental consulting company Microbial Insights in Knoxville (TN) will collect and test soil, sediment, and groundwater samples from impacted areas and those not impacted by pollutants released during the East Palestine accident. Specifically, the project team proposes to combine measurements of biomarkers with complementary cultivation-based efforts of microorganisms that are known to degrade the classes/types of chemical pollutants that were released following the East Palestine train derailment. The successful completion of this project has the potential for transformative impact through the generation of fundamental knowledge to guide and inform the design and implementation of effective pollutant remediation solutions at the East Palestine derailment site and in nearby communities. Additional benefits to society will be achieved through student education and training including the mentoring of one graduate student and three undergraduate students at UT Knoxville. Following the East Palestine train derailment, various hazardous chemicals, including vinyl chloride, butyl acrylate, other volatile and semi-volatile organic compounds (VOCs and SVOCs), and polycyclic aromatic hydrocarbons (PAHs), etc. were released into nearby soils, sediments, groundwater aquifer, and waterways including the Ohio River. However, to date, there has been limited fundamental investigations of the fate and transformations of the hazardous chemicals that were released into the environment three months after the East Palestine accident. The overarching goal of this RAPID project is to establish that microbial communities in impacted areas will show measurable responses, and that these responses could inform about contaminant degradation/detoxification processes and natural attenuation potential at the East Palestine accident site and in nearby soils, sediments, groundwater aquifer, and waterways. The specific objectives of the research are to 1) carry out time-series sampling of soils, sediments, and groundwater in impacted and non-impacted (background) areas, 2) conduct quantitative tracking of contaminant-degrading microorganisms, their dynamics, and their activities in response to the contamination, 3) design and conduct a targeted microcosm treatability study that demonstrates degradation of contaminants by indigenous microorganisms, and 4) synthesize the collected information and research findings to guide and inform the design of a site-specific monitoring program. The successful completion of the proposed research has the potential for transformative impact through the generation of new data and fundamental knowledge to guide the design and implementation of site-tailored monitoring protocols that could comprehensively assess the natural attenuation and contaminant degradation/detoxification potentials of indigenous microbiomes at the East Palestine site and in nearby communities.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
2023年2月3日,俄亥俄州东巴勒斯坦发生货运列车脱轨事故。在列车脱轨之后,各种危险化学品,包括丙烯酸丁酯(BA)、氯乙烯(VC)和燃烧副产物(例如,在火车汽车中剩余的VC和BA的“受控燃烧”中产生的多环芳烃(多环芳烃)被释放到附近的土壤、沉积物、地下蓄水层和水道中,包括为500多万人提供饮用水源的俄亥俄州河。截至2023年5月29日,美国环保署和诺福克南方继续1)在现场和周围社区进行空气监测,2)通过挖掘/处理受污染的土壤和收集/清除受污染的废水来清理脱轨现场。该快速项目将检验以下假设:在受污染物影响的地区,微生物群落将对毒素的释放表现出可衡量的反应,这些反应可以提供有关污染物降解/解毒过程和自然衰减潜力的信息。为了验证这一假设,来自田纳西大学诺克斯维尔分校和环境咨询公司Microbial Insights的主要研究者(PI)和合作研究者将收集和测试受影响地区的土壤,沉积物和地下水样本,以及那些没有受到东巴勒斯坦事故期间释放的污染物影响的地区。具体而言,项目小组建议将生物标志物的联合收割机测量与微生物的补充培养工作相结合,这些微生物已知可以降解东巴勒斯坦火车出轨后释放的化学污染物的类别/类型。该项目的成功完成有可能产生变革性影响,因为它可以产生基础知识,为东巴勒斯坦脱轨现场和附近社区有效的污染物修复解决方案的设计和实施提供指导和信息。对社会的额外好处将通过学生教育和培训,包括一个研究生和三个本科生在UT诺克斯维尔辅导实现。东巴勒斯坦火车出轨事故后,各种危险化学品,包括氯乙烯、丙烯酸丁酯、其他挥发性和半挥发性有机化合物(VOCs和SVOCs)和多环芳烃(PAH)等被释放到附近的土壤、沉积物、地下水含水层和包括俄亥俄州河在内的水道中。然而,迄今为止,对东巴勒斯坦事故发生三个月后释放到环境中的危险化学品的命运和转化情况进行的基本调查有限。该RAPID项目的总体目标是确定受影响地区的微生物群落将表现出可衡量的反应,并且这些反应可以提供有关东巴勒斯坦事故现场和附近土壤、沉积物、地下水的污染物降解/解毒过程和自然衰减潜力的信息含水层和水道。研究的具体目标是:1)对受影响和未受影响的土壤、沉积物和地下水进行时间序列采样;(背景)区域,2)进行污染物降解微生物的定量跟踪,它们的动力学,以及它们响应于污染的活动,3)设计并进行有针对性的微观宇宙可处理性研究,其证明通过土著微生物降解污染物,以及4)综合所收集的信息和研究结果,以指导和通报特定地点监测方案的设计。拟议研究的成功完成有可能产生变革性影响,因为它产生了新的数据和基本知识,可指导设计和实施适合现场的监测方案,全面评估自然衰减和污染物降解。该奖项反映了NSF的法定使命,通过使用基金会的知识价值和更广泛的影响审查标准进行评估,认为值得支持。
