ABC News - Code Red For National Parks - 150 Parks Fail Air Quality Tests

A new study by the National Parks Conservation Association says that one of Teddy Roosevelt's best ideas — the National Park System — is being threatened by air pollution. One of every three of the parks is choking on pollution, the association says. Of the 390 parks within the National Park System, 150 are located in places that fail to meet one or more national healthy-air standards.


"Millions of Americans will be escaping to the national parks Labor Day weekend for clean and healthy fun," the report said. "Unfortunately, many could find 'code red' air-quality conditions and hazy skies." Air pollution is a lingering and insidious problem. It makes it difficult for plants and animals to thrive, and puts the health of park visitors and staff at risk — not to mention what it does to the scenic views.

"That's pollution out there on the horizon," said a visitor to California's Yosemite National Park earlier this summer. "That's why the sunset looks so reddish." In fact, the red sky at dusk was created by tiny particulates in the smoke that had drifted near the park from a brush fire upwind.

Yosemite is not alone. From Acadia National Park in Maine to the Cascades in Washington state, sulfur dioxide, nitrogen oxides, carbon dioxide and mercury can be found at air-monitoring stations in spite of a 30-year congressional mandate to restore clean air to the parks for this and future generations.
