Key Takeaways

After a train derailment sent a plume of thick black smoke into the air over an Ohio village this month, residents are left with questions about their safety and the long-term health effects of toxic chemical exposure.

Fifty train carsderailed and/or caught firewhile passing through East Palestine, a village about 50 miles northwest of Pittsburgh, Pennsylvania. To avert an explosion, authorities conducted a “controlled release” and burn of the toxic material. The days-long blaze created a mushroom cloud of deadly fumes that could be seen for miles.

The train was transporting industrial chemicals, including vinyl chloride, which is known to increase the risk of liver, brain, and lung cancers. More than 1,500 residents were told to evacuate to avoid inhaling the deadly fumes. But within five days, the Environmental Protection Agency (EPA) and local officials said it was safe for residents to return home and that municipal water was safe to drink.

Still, many who live near the site said they’ve experienced headaches, burning sensations in their eyes and throats, and nausea. About 3,500 fish have died near the train derailment, according to the Ohio Department of Natural Resources.Some residents report sick and dead pets, though the Ohio Department of Agriculture said it hasn’t received any official reports about the wellness of farm or domestic animals.

Vinyl Chloride Exposure Has Short- and Long-Term Effects

Vinyl chloride is the primary chemical released from the trains. It is used to make polyvinyl chloride (PVC)—a hard resin used in many plastic products from pipes to bottles.

According to a CDC toxicity report, exposure to the chemical can cause liver damage and liver cancer, harm to the immune system, and birth defects. Workers exposed to high levels of vinyl chloride have also developed conditions likeRaynaud’s phenomenon, as well as joint and muscle pain.

The EPA stopped monitoring air for hydrogen chloride and phosgene on the evening of February 13.

Peter Orris, MD, MPH, senior physician in Occupational and Environmental Medicine at the University of Illinois Chicago Hospital and Health Sciences System, said he felt that the statements of assurance from the EPA and other officials were likely “generated more to calm the public and to avoid panic than to be accurate scientific evaluations.”

The East Palestine incident harkens back to a2012 incidentin which 20,000 gallons of vinyl chloride spilled in Paulsboro, New Jersey. On that day, more than 20 residents sought medical care for symptoms related to vinyl chloride exposure. In a New Jersey Department of Health survey of Paulsboro residents two years after the spill, more than half of the respondents said they had symptoms of vinyl chloride exposure, and more than 250 residents and emergency responders went to hospital emergency rooms due to the leak.

What Cleanup Will Look Like

The U.S. and Ohio EPA said it found spilled toxic materials in the soil and in two streams near the derailment site.

“This cleanup is going to be very difficult—this stuff does go into the ground, contaminates drinking water, lakes, rivers, streams,” Orris said. “They’re going to have to track all of that down. It’s a tremendous task.”

Lawmakers have long tried to overhaul theToxic Substances Control Act. The 1976 law was designed to protect humans and the environment from industrial toxic chemicals, but in reality, containsmany loopholesthat keep the government from effectively regulating chemical companies.

“Avoidance, preparation, and prevention—that ought to be built into the cost of these chemicals and it ought to be built into the thinking of the companies that produce them. This is really rather reckless behavior,” Orris said. “The chemical industry has to take more responsibility for all of our health. And the health impacts and risks have to be taken into better concern in general.”
