City Smog Polluting Wilderness?

"This month researchers at University of California at Riverside, along with representatives from a dozen Western states, will begin developing a model to study the migration of urban smog into wilderness areas. The million dollar project will address the movement of smog from urban centers, which has caused noticeable air qualityproblems in national parks and other areas throughout the west. Metropolitan areas, especially Los Angeles, are mostly to blame for the smog, however, researchers will look at all possible sources, including industry and vehicles from outside areas in addition to pollution caused by park visitors. Researchers expect that the project, which is funded by the EPA, will help determine how smog reaches remote areas and, eventually, how to reduce haze-causing pollution in protected naturalareas.
