DAVIS, Calif. (AP) - California researchers say 10 percent of the Central Valley's smog is coming from as far 6,000 miles away, in Asia.

University of California at Davis atmospheric scientist Ian Faloona presented preliminary results of three years of air-sampling at an air quality conference Tuesday near Yosemite National Park.

Researchers sampled pollutants from a plane and from a mountain near California's Point Sur. The university says researchers were able to identify characteristics of the particles to link them to their origins.

Faloona says the research isn't about assigning blame. He says it's about realizing that local air pollution is a global issue.

California's San Joaquin Valley has some of the most polluted air in the state. Asthma rates are twice that of the rest of California
