The Effects of Chemical Exposure on the Air Quality of East Palestine, Ohio, After a Major Derailed Ohio-Airline Train Collision

Weeks after a major train derailment and controlled explosion of chemicals in East Palestine, Ohio, residents have been encouraged to return home. There are many unanswered questions about how the train derailed, what the chemical exposure could be, and what to do about it.

Those who were not in the East Palestine area were told to stay indoors as a precautionary measure. Air samples from neighboring counties did not show any worrisome levels of contaminates.

James Justice of the U.S. Environmental Protection Agency said that the air monitoring has shown normal levels. Hundreds of data points from that “show that the air quality in the town is safe,” he said.

The controlled release of chemicals from the derailed train did not cause any injuries, but some people have complained that they smelled chlorine in the air and had headaches.

Many nearby residents were ordered to leave their homes immediately after the train accident because they had health risks from the chemicals that were released.

The commander of the Ohio National Guard has previously said that when an order to evacuate was in place, members of the National Guard would wear protective gear and take readings in homes, basements and businesses to make sure the air was safe.

About 50 cars, including 10 carrying hazardous materials, derailed in a fiery crash Friday night on the edge of East Palestine. Federal investigators say a mechanical issue with a rail car axle caused the derailment.

Some business owners and East Palestine residents have filed lawsuits against Norfolk Southern, saying the company was negligent and demanding the company fund court-supervised medical screenings for serious illnesses that may be caused by exposure to those chemicals.

spills happen when trains derail In 2018, a Norfolk Southern train derailed in Pittsburgh, spilling a load of mouthwash and releasing “a strong odor,” according to a city news release. Concern also heightened after the Trump administration allowed rail to transport highly explosive liquid natural gas – a rule the Biden administration halted last year.

A number of people have been reporting burning sensations in their eyes, animals falling ill, and a strong odors in the town since the order to evacuate was lifted.

The Environmental Protection Agency, which has been monitoring the air quality, said it has not detected “any levels of concern” in East Palestine as of Sunday.

The agency added that vinyl chloride and hydrogen chloride have not been detected in the 291 homes that have been screened as of Monday. There are 181 homes that need to be evaluated for indoor air quality.

Breathing or drinking vinylchloride can result in health risks such as dizziness and headaches. People who breathe the chemical over many years may also experience liver damage.

When vinyl chloride is exposed in the environment, it breaks down from sunlight within a few days and changes into other chemicals such as formaldehyde. When it is spilled in soil or surface water, the chemical evaporates into the air quickly, according to the Ohio Department of Health.

The EPA has been monitoring for several other hazardous chemicals, including phosgene and hydrogen chloride, which are released by burning vinyl chloride. Exposure to phosgene can cause eye irritation, dry burning throat and vomiting; while hydrogen chloride can irritate the skin, nose, eyes and throat, according to the Centers for Disease Control and Prevention.

Karen Dannemiller is a professor at The Ohio State University who studies indoor air quality, and says that people are concerned about the long-term exposure that comes at lower levels.

She added that indoor spaces can be an important point of exposure, which is why she urges East Palestine residents to take part in EPA’s at-home air screening.

Dannemiller suggests that people wipe down their surfaces and wash their items that absorb odors. She also advises vacuuming carefully in short bursts to try to prevent contaminants from moving into the air.

Engineers from the National tNuremt’s Materials Laboratory in Washington, D.C. will examine the wheel bearing suspected of being overheated.

The overall investigation will include a metallurgical examination of the wheelset. Once the tank cars are cleaned up, the investigators will be back to finish their examination.

The NTSB said it is reviewing other videos, too, including footage from two local businesses reported by local media to show glowing or flames from the train prior to the derailment.

Authorities were worried about the possibility of a huge explosion and so they burned the debris for days. The controlled detonations release the chemical which can kill at high levels and increase cancer risk. The hazardous substance spilled into a trench, where it was burned away.

“If this is true – and I’m told it’s true – this is absurd,” DeWine said. “We should know when we have trains carrying hazardous material that are going through the state of Ohio.”

According to the Ohio EPA, almost 500 gallons ofvinylchloride- impacted material has been removed, and the dirt near the train wreck remains contaminated.

Ohio EPA and state officials performed many different tricks to try and contain the pollution from the chemical spill. There are oil containment booms in the water and contaminated soil.

The Ohio River is a large body of water, and it is capable of expelling pollutants very quickly.

The chemicals are a “contaminant plume” that the Ohio EPA and other agencies have been tracking in real time. It’s believed to be moving about a mile an hour, Kavalec said.

The “tracking allows for potential closing of drinking water intakes to allow the majority of the chemicals to pass. This strategy along with drinking water treatment help ensure the safety of the drinking water supplies and they are pretty confident that the low levels of contaminants that remain are not being passed onto customers.

Still, authorities are strongly recommending that people in the area use bottled water for drinking, especially if their water is from a private source, such as a well.

How hazardous is the risk of derailment and explosion? Anecdotes from the Ohio Department of Natural Gas and Environmental Protection after the Ohio Chemical Spikes

The chemical spill took a severe toll on local aquatic life: About 3,500 fish ranging across 12 species died from the water contamination washing down streams and rivers.

Initial testing and sampling were performed by the state agency to estimate the number of dead fish. There was an increase in the number of dead fish after the accident, but it seems like that has stopped.

The pits of dirt are 700 feet long and 8 feet deep, according to the on-scene leader for the Ohio EPA.

When asked about anecdotal reports of people getting headaches and sore throats, and of animals, such as cats and chickens, dying near the train derailment, Ohio Health Director Dr. Bruce Vanderhoff said that air quality does not appear to be the source.

necdotes are challenging because they are anecdotes. “Everything that we’ve gathered thus far is really pointing toward very low measurements, if at all.”

This is in large part because railroads are considered the safest mode of transportation to carry large amounts of hazardous materials, including chemicals, for long distances across the country, according to the Federal Railroad Administration.

“It’s the mode of transportation that’s capable of moving bulk quantities,” Federal Rail Administration spokesperson Warren Flatau told CNN. “These commodities cannot be moved by pipeline; the alternative is moving them by truck over the highways, which is not looked upon favorably.”

According to the USA Today analysis, there were at least two plane and 67 highway rail leaks last year.

“The real issue is the risk of derailment and explosion,” Kimberly Garrett, a researcher and PFAS expert at Northeastern University. If natural gas went off like the vinyl chloride it would be devastating.

The Ohio Environmental Protection Agency has been conducting air, soil and water tests since the controlled explosion of the chemicals inside the rail cars.

Whelton told CNN the EPA should also continue to monitor semi-volatile organic compounds, which are more persistent and detected in local waterways after the derailment.

“Because of their size, they don’t go in the air as easily,” Whelton said. “They like to stick to soils and other materials. The question is: How contaminated is the creek?

Anecdotal reports of pets and chickens dying have not yet been confirmed by officials. The director of the Ohio Department of Natural Resources said there was no evidence that animals outside of the water had been affected by the spill.

Kurt said that crews have excavated and removed over 500 feet of material from the site. The EPA is trying to keep the contaminated dirt out of the water.

As for drinking water, Kavalec said water treatment facilities should be able to remove the remaining low levels of volatile organic compounds in the water, and that the water will eventually be safe to drink.

The chemicals officials say should break down with aeration and water treatment are potentially more hazardous than the class of chemicals used to put out chemical fires.
