EPA ORDERS TESTING FOR HIGHLY TOXIC DIOXINS IN OHIO
After weeks of questions about contamination associated with a train derailment in East Palestine, Ohio, the Environmental Protection Agency on Thursday ordered rail company Norfolk Southern to test the area for dioxins, a dangerous and persistent class of pollutants created when plastic is burned. The train that crashed there Feb. 3 was carrying chemicals used to make plastics.
A chorus of academics, environmentalists and residents have been raising the alarm about potential dioxin contamination because, days after the derailment, authorities seeking to avoid an explosion purposefully released and burned the chemical vinyl chloride, a key component of PVC plastic.
While EPA officials said monitoring for related chemicals around East Palestine suggests a “low probability” of dioxin contamination, Administrator Michael Regan said the agency is directing the railroad to conduct testing for the pollutants based on concerns from the community.
EPA will oversee the testing and “direct the company to conduct immediate cleanup if contaminants from the derailment are found at levels that jeopardize people’s health,” Regan said in a statement.
“Over the last few weeks, I’ve sat with East Palestine residents and community leaders in their homes, businesses, churches, and schools. I’ve heard their fears and concerns directly, and I’ve pledged that these experiences would inform EPA’s ongoing response efforts,” the EPA administrator added.
Dioxins are produced when burning anything from wood and fossil fuels to municipal waste and cigarettes. Combustion releases chlorine stored in those substances, which reacts with other compounds to form dioxins. The pollutants are of particular concern when plastic is burned because chlorine is a key element of plastics, including PVC and vinyl chloride.
Dioxins are linked to cancer, reproductive and developmental problems, and immune system damage. They are particularly troublesome toxins because they are slow to break down in the environment and also build up in the food chain. The EPA said most human exposure to dioxins in the United States is tied to releases that occurred decades ago.
