Assessing the Health Risks and Air Quality Following a Freight Train Derailment in Ohio

In early 2023, a freight train derailment in East Palestine, Ohio, raised concerns about the release of industrial chemicals and their impact on the local air quality and the health of residents¹. The Norfolk Southern freight train was carrying several hazardous chemicals that posed a significant risk if not handled properly². To avoid a catastrophic explosion, authorities chose a controlled release of gases and decided to burn the contents of the train cars, which included toxic vinyl chloride³.

However, the potential health risks and environmental hazards prompted researchers from Carnegie Mellon University in Pittsburgh and Texas A&M University to investigate the situation in depth⁴. Using data from the U.S. Environmental Protection Agency (EPA), the research team assessed the local air quality and identified elevated levels of certain dangerous gases, with acrolein being a particularly concerning respiratory irritant⁵.

Their findings, published in the American Chemical Society’s Environmental Science & Technology Letters, revealed that nine out of fifty gases reached levels above their baseline, indicating potential health risks⁶. It’s important to note that these risks were specific to the time of assessment and could vary depending on the ongoing cleanup activities⁷.

The researchers employed both stationary and mobile sampling methods to evaluate air quality⁸. They utilized air-quality monitoring data from two EPA stations as fixed locations, and also conducted mobile monitoring by driving a cargo van around the area for two days⁹. The van was equipped with a mass spectrometer capable of identifying various gases in the vicinity of the accident site¹⁰.

The mobile monitoring was especially valuable as it allowed the research team to detect changes in gas concentrations over time and space¹¹. During the day, acrolein and butyl acrylate were found to be up to six times higher near the accident site compared to background levels, while dropping to background levels at night¹². These fluctuations highlight the importance of ongoing assessment to accurately understand the evolving situation and mitigate potential risks¹³.

While initial concerns were raised about the long-term impact of vinyl chloride and other pollutants, the researchers discovered that the concentrations of many pollutants declined significantly as time passed¹⁴. For example, concentrations of vinyl chloride decreased to levels below long-term limits of health concern, providing some relief to residents¹⁵.

The study’s results underscore the need for comprehensive air-quality assessment, utilizing both stationary and mobile methods, as cleanup activities proceed¹⁶. The combination of these approaches enables a more thorough understanding of the dynamic nature of air pollution, facilitating informed decision-making and risk management¹⁷.

It is essential to prioritize public health and environmental protection during industrial accidents and ensure effective cleanup measures to minimize any potential adverse effects on nearby communities. Continued monitoring and research in collaboration with relevant regulatory bodies are necessary to ensure the long-term well-being of affected populations, as well as to provide valuable insights into industrial accidents and their aftermath.
