Montgomery County, Ohio: environmental and disease records

Cancer mortality in Montgomery County is 157.9 deaths per 100,000 people per year against a U.S. rate of 143.2, a statistically significant excess. The strongest disease signals are Melanoma of the skin deaths at 1.4 times the U.S. rate and Lung & bronchus deaths at 1.3 times the U.S. rate. Federal databases place 1,225 regulated facilities, sites and hazards inside the county, led by Air permit holder (minor source) (377), Gas station (mapped facility) (218), Rail grade crossing (120). EPA AirToxScreen estimates a lifetime cancer risk from outdoor air toxics of 30 in a million, driven mainly by formaldehyde.

Rates are age-adjusted per 100,000 people. A cancer signal is marked significant when the lower bound of its 95 percent confidence interval is above the U.S. rate. Facility counts use active federal records located inside the county boundary. Approximate county center: 39.7479, -84.2916.
