"FRESNO, Calif. — This is the time of year when residents who often live with the nation's worst pollution often can draw a breath of fresh air. But this winter has not been kind to people who want to play outside in California's Central Valley."
"A dry December and January has stagnated air across California, but nowhere is the situation more serious than between Modesto and Bakersfield, where nearly every day dirty air has exceeded federal health standards.
It's the worst air quality recorded in a dozen years, and it's the unhealthiest kind_ microscopic, chemical-laden particles that can get into lungs and absorbed into the bloodstream to create health risks in everyone, not just the young and infirm."
Tracie Cone reports for the Associated Press January 7, 2012.
