A train derailment that occurred on February 3rd near East Palestine, Ohio, involved hazardous materials that has caused environmental concerns for residents, despite the reassurances of state officials. Many have complained of strong smells, headaches and nausea, and some have experienced rashes. A "controlled explosion" was carried out to burn off five rail cars' worth of vinyl chloride, resulting in the area's temporary evacuation. The Ohio Department of Health director reported that monitoring of air and water had shown no levels of health concern and that the air was pretty much as it was before this event. However, some residents are still concerned, and the governor of Ohio is urging Congress to change rules around hazardous cargo notification. The incident has gained national attention as many residents continue to report side effects two weeks later.
