Canton's air quality in Ohio reflects the Tuscarawas River valley's position in northeast Ohio, with the legacy of steel and manufacturing industry in the Stark County corridor contributing elevated PM2.5 alongside vehicle traffic on I-77. The surrounding northeast Ohio hills create modest topographic variation, while the broader Ohio Valley regional airshed contributes elevated industrial background PM2.5 and summer ozone from the dense manufacturing and energy production corridor.
