MT / county disease rankings

Counties with the highest air toxics cancer risk in Montana

Among 56 Montana counties with published values, the counties with the highest air toxics cancer risk are Missoula County, MT (30, 1 times the U.S. county median of 30), Big Horn County, MT (20, 0.67 times the U.S. county median of 30) and Cascade County, MT (20, 0.67 times the U.S. county median of 30). Values are in a million (EPA AirToxScreen).
