Residents affected by the train derailment and subsequent chemical fallout in East Palestine, Ohio, could be subject to a number of long-term health complications as a result of prolonged exposure to toxic substances despite officials’ assurances that the air and water in the town is safe, researchers from Texas A&M University and Carnegie Mellon University said on Friday.

Local and state authorities previously evacuated all residents within one mile of the February 3 derailment and started a controlled burn of industrial chemicals on the vehicle to decrease the risk of an explosion, which could have sent shrapnel throughout the small town. Vinyl chloride, a known human carcinogen used to manufacture PVC, was emitted from five train cars in the form of massive plumes of black smoke visible throughout eastern Ohio and western Pennsylvania.

The researchers from Texas A&M and Carnegie Mellon said on Friday that nine of the approximately 50 chemicals that the EPA said were present on the derailed train have higher concentrations than normal in East Palestine. They were especially concerned with above normal levels of acrolein, a substance with a pungent odor that is “highly toxic” when inhaled, according to a report from the CDC.

“If these levels continue, they may be of health concern,” the analysis said.

The findings come after the EPA said that “test results from the village’s municipal well sampling showed no water quality concerns,” while Governor Mike DeWine (R-OH) announced that tests conducted by the Ohio EPA revealed “no detection of contaminants in raw water from the five wells that feed into East Palestine’s municipal water system.” A team of Daily Wire journalists and producers who visited East Palestine nevertheless reported a lingering smell in the air, an oily chemical sheen in local creeks and rivers, and symptoms such as sore throats and headaches garnered merely by spending an extended period of time in the community.
