Central Ohio Air Within Federal Soot Limits
Montgomery County has some of the dirtiest air in Ohio, while the air in central Ohio is within federal pollution limits.
The Ohio EPA says Montgomery is one of seven counties that failed to meet a new federal standard for soot. The agency says concentrations of soot in central Ohio's air are down this year, and are below the federal limits set in December of last year. Soot is formed by vehicle, factory, and power plant emissions. Officials say soot causes asthma attacks, heart problems, and other health issues.
