McKinney's air quality reflects the Dallas metropolitan area's rapidly growing northern corridor, with vehicle emissions from US-75 and the SH-121 generating elevated NOₓ from concentrated suburban commuter traffic. The flat North Texas plain provides reasonable wind dispersal, while the broader DFW metropolitan ozone challenge from vehicle and Barnett Shale gas emissions affects the entire northern corridor throughout the summer ozone season.
