Texas has seen more days with unhealthy levels of smog pollution this year than it has in a decade, state data shows, as vehicle and industrial emissions react with record-high temperatures, spiking ozone concentrations.
Since the beginning of the year, Texas air monitors have recorded 43 days as of Tuesday when ozone concentrations were high enough somewhere in the state to be considered unhealthy by the Environmental Protection Agency. That’s double the number of unhealthy ozone days recorded by this time last year, and it’s the most in the period of January to mid-July since 2012, air monitoring data maintained by the Texas Commission on Environmental Quality shows.
Ground-level ozone, a component of what’s known as smog, irritates and inflames the lungs, leaving them more susceptible to infections such as the coronavirus that causes COVID-19, and making it harder for people to breathe. Ozone can make lung diseases worse, prompt asthma attacks and cause or aggravate chronic bronchitis. The pollutant is especially concerning when combined with extreme heat, experts said.
