Payam Javan: According to the American Lung Association, which analyzes ozone and particle pollution across the country, San Joaquin County has some of the poorest air quality in the state. Failing ratings were also issued to Sacramento, Stanislaus, Tuolumne, and Calaveras counties.
Experts say the county’s dismal air quality rating is not surprising.
“Air quality impacts health. Anyone can be put at risk if there’s a day with unhealthy levels of air pollution,” said Laura Kate Bender, with the ALA. “San Joaquin County did see a few days on which the air quality reached very unhealthy levels.”
