East Palestine residents worry rashes, headaches and other symptoms may be tied to chemicals from train crash

Some residents of East Palestine, Ohio, say they have developed rashes, sore throats, nausea and headaches after returning to their homes this week, and they’re worried these new symptoms are related to chemicals released after a train derailment two weeks ago.

The February 3 incident caused a massive fire and prompted officials to evacuate hundreds of people who lived near the site because of fears that a hazardous, highly flammable material might ignite. To prevent a potentially deadly explosion, toxic vinyl chloride gas was vented and burned, releasing a plume of black smoke over the town for days.

Other chemicals of concern at the site include phosgene and hydrogen chloride, which are released when vinyl chloride breaks down; butyl acrylate; ethylene glycol monobutyl ether acetate; and 2-ethylhexyl acrylate, according to the US Environmental Protection Agency. All these chemicals can change when they break down or react with other things in the environment, creating a stew of potential toxins.
