After a freight train loaded with chemicals derailed in the US state of Ohio, local residents are concerned about the health consequences. The director of the US Environmental Protection Agency (EPA) tried to calm people down during a site visit.

"We are assisting local authorities in determining the impact of the accident and making sure there is no impact on drinking water supplies," said Michael Regan. Both the water and the air are regularly tested for dangerous pollutants. "This incident understandably shook this community to its core."

The train derailed and burst into flames in the East Palestine community in early February. A huge plume of smoke hung over the site near the Pennsylvania state line. He was temporarily evacuated.

Railway company under criticism

Since the accident, residents have complained about health problems - including headaches, irritated eyes and rashes. They accuse the authorities of incomplete information policy and feel let down. The railway company "Norfolk Southern" has also been criticized and stayed away from a meeting with local residents.

EPA director Regan stressed that no traces of chemicals such as vinyl chloride or hydrogen chloride were found during the examination of 480 houses. "The health and safety of the population is our top priority," said White House spokeswoman Karine Jean-Pierre. Local authorities now fear rain could wash pollutants into local streams and rivers.

At the same time, the state's disaster management agency tried to appease local residents. Odors could be perceived. This is because some of the pollutants released have a low odor threshold. These pollutants could therefore be smelled at levels well below what is considered dangerous.
