From Texas Public Radio:
About 17 million Texans live in areas that consistently have unhealthy levels of ozone or particle pollution. That figure comes from the American Lung Association’s annual “state of the air” study, which was published Tuesday.
“We look at the air quality index and figure out basically the number of days that get to the unhealthy levels of air pollution for either ozone or particle pollution,” said Will Barrett, the clean air advocacy director with the American Lung Association.
People with pre-existing respiratory conditions are more likely to die if they contract COVID-19, and people who live in areas with poor air quality are more likely to develop respiratory conditions.
