SAN ANTONIO -- Some people in San Antonio could be at risk for health issues because of the city's air quality.

The City released a study that found increases in the city's ozone could increase ozone-related deaths.

It estimates 19 respiratory deaths would be the result each year, if the air quality depreciates to what it was in 2012. The cost linked to these deaths is roughly $170 million.

To raise awareness, San Antonio started a public education campaign to encourage residents and business to keep the city's air clean.
