Counties with the highest air toxics cancer risk in California

Among 58 California counties with published values, the counties with the highest air toxics cancer risk are Santa Cruz County, CA (70, 2.33 times the U.S. county median of 30), Butte County, CA (50, 1.67 times the U.S. county median of 30) and Placer County, CA (50, 1.67 times the U.S. county median of 30). Values are in a million (EPA AirToxScreen).
