Residents of East Palestine, Ohio, are complaining of headaches, trouble breathing and other symptoms after a nearby train derailment that spilled millions of liters of industrial chemicals last month. Local, state and federal officials and train operator Norfolk Southern monitor water and air quality in the town, but community members are unsatisfied with the official reports. They claim that the chemical levels are low and safe.
Several independent researchers have arrived on the scene, hoping to help with more measurements and analyses. Some were invited by residents seeking a second opinion. The team believes it will help fill the gap left by the authorities.
Ivan Rusyn, director of the Texas A&M University Superfund Research Center in College Station, said:
Rusyn is part of a group of researchers from Texas A&M University and Carnegie Mellon University in Pittsburgh, Pennsylvania, who drove a mobile laboratory to measure air quality around Eastern Palestine on February 20 and 21. bottom. Many of their measurements matched those of the EPA. However, researchers detected levels of acrolein, a chemical irritant that affects the eyes, skin and respiratory system. This was three times his level in downtown Pittsburgh, about 50 miles away. (Rural areas, such as eastern Palestine, typically have lower levels of air pollutants than urban areas.) Scientists believe that if these levels persist, they could affect the health of residents. said.
On February 6, three days after the train crash, authorities evacuated a five-square-kilometer area that includes eastern Palestine. They cut holes in the train cars and dumped the chemicals they were carrying, including vinyl chloride and butyl acrylate, into the pits. This was followed by a ‘controlled burning’ of the material to avoid an explosion. The explosion created a huge black cloud over the site, presumably producing acrolein and other combustion byproducts.
In a statement to Naturethe EPA detected slightly elevated levels of acrolein in eastern Palestine in the weeks following the derailment, but said these levels did not pose a health risk in the short term. concentrations have returned to levels below the national median,” the agency said.
need more sampling
The Texas A&M and Carnegie Mellon team’s findings point to a broader set of chemicals, not just those that were spilled during train derailments or likely formed during controlled combustion. Emphasizes the importance of research. Albert Presto, a member of the Center for Atmospheric Particles Research at Carnegie Mellon University, said in his briefing online on March 3 that it takes time to do an “asymmetric analysis” to find less noticeable compounds. said it was important.
In addition to acrolein, the group found four more acrolein-like compounds than in the area surrounding East Palestine, another compound of concern in certain hot spots. “We need more sampling,” he says Rusyn. Especially since crews working on cleanup operations continue to excavate contaminated soil and aerate water in local streams to extract chemicals. This could release more compounds into the air, he adds.
One of the problems researchers at Texas A&M and Carnegie Mellon see in the government response is the failure to communicate clearly with residents. For example, Rusyn says it’s not clear if field agencies have considered the effects of long-term exposure when they say a chemical level is safe.
When asked what it was considering, the EPA said: Nature During the first two weeks of emergency response, it is important to focus on short-term exposure concerns, and that work may shift to long-term concerns over time.
Nicole Kahn, a chemist at Ohio State University in Columbus, says the official report is difficult to interpret, even for scientists. “There is already a lot of skepticism among residents about whether the EPA is true,” he says Karn. [agency officials] It will be a struggle to regain trust.”
Keith Richel, an Eastern Palestinian who lives five blocks from the train derailment site, said he still smells a strong chemical that comes and goes with the weather, and his family suspects he’s involved. He said he was experiencing symptoms. to spills. His wife has a rash on her back and he has a nosebleed. He doesn’t trust his EPA test results. He has hired an independent contractor to test the soil in his home and is awaiting results.
In a statement, the EPA posted daily updates on its website and said it was “actively looking for ways to better explain the information.” The agency also has a welcome center in town, a 24-hour hotline, and a weekly open house where residents can ask questions.
get the answer
This isn’t the first time independent researchers have been called in to assess chemical hazards. In 2014, after Flint, Michigan switched its drinking water source from Lake Huron to the Flint River, residents noticed a change in the taste, smell and appearance of the water. Unhappy with officials’ statements that the water was safe, they sought a second opinion. In 2015, researchers found dangerous levels of lead in the water, in part because of the city’s water treatment decisions.
Mona Hannah Atticia, a public health researcher at Michigan State University in East Lansing, was part of the effort. In situations like Eastern Palestine, she says, it’s important for authorities and health care providers to have a trauma-based response. “This is a whole community that has experienced trauma,” she says. “Anxiety is having a negative impact on their health.
Andrew Welton, an environmental and ecological engineer at Purdue University in West Lafayette, Indiana, agrees that residents of Eastern Palestine are terrified. He visited the town in late February after being contacted by regional group United Four East in his Palestine. “They were reporting health effects and concerns,” he says. “And they weren’t getting answers.”
Along with colleagues and students, he visited homes, interviewed residents, and collected water samples from private wells, taps, and two local streams. Welton’s team and other researchers at Purdue University analyzed the samples and found several chemicals that may have been released after the accident, including acrolein. We are determining the exact levels of the compounds and whether they are of concern.
But Welton said the stream water, in particular, was “slimy” and had a “peculiar sharp smell.” According to the EPA, water from municipal systems is safe to drink. Government agencies are encouraging people using private wells to drink bottled water until the wells are inspected.
Richeal applauds the efforts of the scientists. “It’s very important that independent researchers are doing this,” he says. He’s especially concerned about the long-term effects. But what happens when all this rain falls and everything falls to the ground? “
