The EPA says it began testing air quality in the East Palestine area within 24 hours of the derailment, including the use of a mobile analytical laboratory. The agency said Tuesday that it has assisted with indoor air monitoring of more than 550 homes under a voluntary screening program offered to residents, and that “no detections of vinyl chloride or hydrogen chloride were identified above levels of concern.” The EPA is testing to make sure home air concentration of the chemicals does not exceed 0.5 parts per million for vinyl chloride and 1.4 ppm for hydrogen chloride. เว็บบอล 365
