A multi-year study conducted by the South Coast Air Quality Management District has found that cancer risk from air pollution is down overall by 8 percent. However, some areas of the region have an increased risk.

Increases of 17% were found around the port areas in Long Beach and Los Angeles. Slight increases were also found in areas of Riverside County probably due to increased truck traffic warehouse development as by-products of the growth in trade at the ports.

"About 84 percent of all cancer risk from air pollution is due to diesel exhaust from trucks, trains, ships, locomotives and other diesel equipment," stated the AQMD's statement on the study. "The remaining risk is due to toxic emissions from gasoline-powered motor vehicles, businesses and industrial facilities."
