Counties with the highest air toxics cancer risk in Pennsylvania

Among 67 Pennsylvania counties with published values, the counties with the highest air toxics cancer risk are Allegheny County, PA (40, 1.33 times the U.S. county median of 30), Greene County, PA (40, 1.33 times the U.S. county median of 30) and Washington County, PA (40, 1.33 times the U.S. county median of 30). Values are in a million (EPA AirToxScreen).
