(April 20, 2016) -

SAN ANOTNIO – The American Lung Association’s 2016 “State of the Air” report found San Antonio ranked as the 32nd most polluted city in the nation for ozone. Compared to the 2015 report, San Antonio has cut ozone slightly. This is in keeping with a trend seen across the nation of lower ozone pollution levels. 

“The 2016 ‘State of the Air’ report finds unhealthful levels of ozone in San Antonio, putting our local citizens at risk for premature death and other serious health effects such as asthma attacks and cardiovascular harm.” said Angie McClure, Executive Director of the American Lung Association in Texas - San Antonio/Austin. “Across the nation, the report found continued improvement in air quality, but more than half of the people in the United States live in counties that have unhealthful levels of either ozone or particle pollution.”

Each year the “State of the Air” reports on the two most widespread outdoor air pollutants, ozone pollution and particle pollution. The report analyzes particle pollution in two ways: through average annual particle pollution levels and short-term spikes in particle pollution. Both ozone and particle pollution are dangerous to public health and can be lethal. But the trends reported in this year’s report, which covers data collected in 2012-2014, are strikingly different for these pollutants nationwide, and also in San Antonio.

Ozone Pollution in San Antonio

Compared to the 2015 report (2011-2013), San Antonio experienced fewer unhealthy days of high ozone in this year’s report. 

“Ozone is harmful to public health and especially children, older adults and those with asthma and other lung diseases,” said McClure. “When older adults or children with asthma breathe ozone-polluted air, too often they end up in the doctor’s office, the hospital or the emergency room.” 

Nationwide, ozone pollution has decreased because the nation has cleaned up major sources of the emissions that create ozone, especially coal-fired power plants and vehicles. However, according to research, climate change causes warmer temperatures, which makes ozone harder to clean up. 

Particle Pollution in San Antonio

The 2016 report found year-round particle pollution (soot) levels in 2012-2014 slightly lower than the 2015 report. Nationwide, the best progress in this year’s report came in reducing year-round levels of particle pollution. In fact, San Antonio along with 15 other cities reached their lowest levels ever, and three others improving over the period covered by the 2015 report.

“Particle pollution is made of soot or tiny particles that come from coal-fired power plants, diesel emissions, wildfires and wood-burning devices. These particles are so small that they can lodge deep in the lungs and trigger asthma attacks, heart attacks and strokes, and can even be lethal,” said Kamp. “Year-round particle pollution levels have dropped thanks to the cleanup of coal-fired power plants and the retirement of old, dirty diesel engines.”

The 2016 report also tracked short-term spikes in particle pollution, as these can be extremely dangerous and even lethal. According to the 2016 report, San Antonio has no unhealthy air days in 2012-2014. This is in spite of a trend seen across the nation of short-term spikes in particle pollution.
