Researchers say high levels of chemicals at Ohio train derailment site could pose long-term risks

An analysis of data from the US Environmental Protection Agency’s measurements of pollutants released from the Norfolk Southern train derailment in East Palestine, Ohio, suggests that nine of the dozens of chemicals that the EPA has been monitoring are higher than would normally be found in the area, according to a group of scientists from Texas A&M and Carnegie Mellon University. Scientists say that if the levels of some of these chemicals remain high, it could be a problem for residents’ health in the long term. Additionally, potential temperature changes or high winds might stir up the chemicals and release them into the atmosphere. The analysis says, that the highest levels found in East Palestine were of the chemical acrolein. Acrolein, at room temperature, is a toxic clear liquid that is used to control plants, algae, rodents, and microorganisms. According to the US Centers for Disease Control and Prevention, it can cause inflammation and irritation of the skin, respiratory tract, and mucous membranes. Associate research professor of mechanical engineering at Carnegie Mellon’s Wilton E. Scott Institute for Energy, Dr. Albert Presto said “it’s not elevated to the point where it’s necessarily like an immediate ‘evacuate the building’ health concern.” As of Sunday, the EPA and local government officials have tested the air in 578 homes, and they claim the chemical pollution levels have not exceeded residential air quality standards. However, Presto said that residents have reported rashes and trouble breathing, sometimes in their own homes. The EPA says that it will continue to monitor the air quality in the area and residents’ homes. The agency is also setting up a community center so that residents and business owners can ask questions about the agency’s activity there.
