The increasing prevalence of hazardous chemical incidents in the United States necessitates the implementation of analytically robust, rapid, and reliable screening techniques for toxicant mixture analysis to understand short- and long-term health impacts of environmental exposures. A recent chemical disaster in East Palestine, Ohio has underscored the importance of thorough contamination assessment. On February 03, 2023, a Norfolk Southern train derailment prompted a chemical spill and fires. An open burn involving over 100,000 gal of vinyl chloride was conducted three days later. Hazardous compounds were released into air, water, and soil. To provide time-sensitive exposure data for emergency response, this study outlines a novel methodology for rapid characterization of chemical contamination of environmental media to support disaster response efforts. A controlled static headspace sampling system, in conjunction with a high-resolution proton transfer reaction time-of-flight mass spectrometer (PTR-TOF-MS), was developed to characterize volatile organic compounds (VOCs) in surface water samples collected near the East Palestine train derailment site. Spatial variations were observed in the chemical composition of surface water samples collected at different locations. Hydrocarbons were found to be the most abundant chemical group of all surface water samples, contributing 50 % to 97 % to the total headspace VOC mass. Compounds commonly detected in surface water samples, including benzene, styrene, xylene, and methyl tert-butyl ether (MTBE) were also observed in most surface water samples, with aqueous concentrations typically at ng/L levels. This study demonstrated the potential of the proposed methodology to be applied for rapid field screening of volatile chemicals in water samples in order to enable fast emergency response to chemical disasters and environmental hazards.

What drives household protective actions in an industrial crisis? Insights from the East Palestine train derailment
Complex industrial disasters illustrate the challenges of underdeveloped public warning systems. Unlike most natural disasters, quickly identifying hazardous materials and assessing their threats is crucial for developing protective action recommendations (PARs) that guide household response in industrial crises. The 2023 East Palestine, Ohio (USA) train derailment, chemical spill, and fires revealed that gaps in rapidly identifying hazardous materials, and the threats they present, can severely impact the public warning system. As the crisis unfolded, responding agencies left crucial questions unanswered, leaving community members uncertain about their safety, the extent of environmental contamination, and what protective actions to take. It is imperative to study the drivers of household protective actions in the absence of a developed warning system and well-established PARS. To achieve this, we conducted a community survey in Ohio, Pennsylvania, and West Virginia (n = 259) in response to the East Palestine crisis. We used multivariate logistic regressions to identify statistically significant explanatory factors that predict protective action response. Our findings reveal gaps in response, where challenges identifying and communicating hazards created environmental justice concerns. We provide policy recommendations to strengthen hazard identification and outline further work to include equity as a pillar of environmental disaster response.

This dataset includes anonymized survey data collected in communities affected by the East Palestine train derailment, chemical spill, and fires. The survey was designed to capture community perceptions and experiences related to air, water, and soil sampling and testing; household and built environment impacts; and protective actions taken. Participants were eligible to participate if they were 18 years or older and lived or worked in an affected county as of February 3, 2023—the day of the derailment. The survey was open from July 20 to September 20, 2023, approximately six months after the incident. See "Notes" below for more details on the methods. The research was reviewed and approved by the Human Subjects in Research Ethics boards at the authors’ universities. This research is supported by the National Science Foundation (Award #2329409).more » « less

Recent research in crisis and risk communication has examined information seeking preferences across varying audiences in the time leading up to natural disasters. Such an understanding is critical for targeting risk information messages such that they will have the maximum intended impact on those seeking to take protective actions. Until recently, these studies have largely ignored the relative importance of mediated sources alongside community groups and other grassroots organizations. To that end, the current study surveyed 1030 Florida residents in the aftermath of 2022’s Hurricane Ian in the United States. In addition to replicating past findings concerning media preferences across the demographic spectrum, the current study offers evidence that marginalized and at-risk communities may be especially reliant on community resources for information about protective actions concerning an environmental hazard. The findings are discussed in terms of their implications for crisis communication researchers and emergency managers alike.more » « less

Organizations and communities learn by collecting information both from their direct, experiences and by observing others. Information is translated into knowledge, which is disseminated and used to inform subsequent planning, decisions and actions. Among the experiences and observations of organizations and communities that can be translated into knowledge are crises and disasters, including infections disease outbreaks, water contamination events and natural disasters. Organizational and community learning occurs when knowledge generated in response to crises is applied and when previous events serve as the basis for informing responses to an anticipated risk or emerging crisis. Trial-and-error learning is an ongoing process of experimentation, assessment and evaluation. Through trial and error, it is possible to determine that an activity does not produce desired outcomes, allowing for strategies to be adjusted and refined. Communities and organizations also benefit from observing others facing similar threats and learn from their failures and successes. Vicarious learning is bolstered through publicly available information, such as media reports and web presence, and access to networks of similar organizations. Crises can provide opportunities to re-evaluate fundamental assumptions, norms, processes, structures, plans, technologies, and overall performance. This session provides an overview of learning from crises and presents cases from the COVID-19 pandemic response, water contamination events, and natural disasters. The COVID-19 response in the City of Detroit offers important lessons about public health disparities, community engagement, and sustained responses. Cases studies of learning from the Flint Water Crisis and the Toledo Water Crisis illustrate how organizations and communities can translate experience into knowledge. Natural disasters can reveal systemic vulnerabilities and deficiencies in knowledge. Winter Storm Uri impacted Texas in mid-February 2021, bringing cold temperatures, record-levels of snow, and damaging ice and devastating the electrical grid, prompting widespread boil water notices. This case provides lessons about informing the public about emerging risks and about how they respond. These cases show how organizational learning may help organizations and communities prevent the repetition of a similar crisis, plan and respond more effectively.more » « less

The East Palestine, Ohio train derailment released toxic vinyl chloride (VC) and butyl acrylate (BA), which entered the watershed. Streambed sediment, surface water, and private well water samples were collected 128 and 276 days postaccident to assess the natural attenuation potential of VC and BA by quantifying biodegradation biomarker genes and conducting microcosm treatability studies. qPCR detected the aerobic VC degradation biomarkers etnC in ∼40% and etnE in ∼27% of sediments collected in both sampling campaigns in abundances reaching 10e5 gene copies g−1. The 16S rRNA genes of organohalide-respiring Dehalococcoides and Dehalogenimonas were, respectively, detected in 50 and 64% of sediment samples collected 128 days postaccident and in 63 and 88% of sediment samples collected 276 days postaccident, in abundances reaching 10e7 cells g−1. Elevated detection frequencies of VC degradation biomarker genes were measured immediately downstream of the accident site (i.e., Sulphur Run). Aerobic VC degradation occurred in all sediment microcosms and coincided with increases of etnC/etnE genes and Mycobacterium, a genus comprising aerobic VC degraders. The conversion of VC to ethene and an increased abundance of VC reductive dechlorination biomarker genes were observed in microcosms established with sediments collected from Sulphur Run. All anoxic microcosms rapidly degraded BA to innocuous products with intermediate formation of n- butanol and acrylate. The results indicate that microbiomes in the East Palestine watershed have natural attenuation capacity for VC and BA. Recommendations are made to improve first-response actions in future contaminant release accidents of this magnitude.more » « less
