ST. LOUIS - The American Lung Association finds the St. Louis Metro area’s air quality has improved.
The ozone has improved in the area, but it still has a long way to go.
Pollutants can cause severe asthma attacks, particularly in vulnerable children.
"Particle pollution is especially risky for cardiovascular harm, like heart disease, stroke,” said Janice Nolen of the American Lung Association. “It also is greatly risky for people with diabetes and it causes lung cancer."
