Worst national parks for air quality listed

[dArKeR]

Planning to visit any national parks this summer? If so, a report out Thursday stamps a stigma on five that it labels as having the worst air quality in the system of 388 national parks.

Authored by the National Parks Conservation Association and two smaller groups, the report concludes that air quality in the national parks has not improved even though Congress tightened the Clean Air Act in 1990.

That poor quality affects not only views, the activists noted, but can have long-term, detrimental health effects on plants, trees and animals.

Using haze, acid precipitation and ozone, also known as smog, as their criteria, the groups ranked these five parks in order of having the worst air quality:

Using haze, acid precipitation and ozone, also known as smog, as their criteria, the groups ranked these five parks in order of having the worst air quality:

Great Smoky Mountains National Park in Tennessee and North Carolina. Named for its naturally occurring blue haze, the park rated worst in terms of acidity and second worst for smoggy days as well as haze, with average summer visibility for 1999-2003 at 20 miles. Natural visibility for the parks studied ranged from 80-120 miles.

Mammoth Cave National Park in Kentucky. Average summer visibility: 17 miles.

Shenandoah National Park in Virginia. Average summer visibility: 24 miles.

Acadia National Park in Maine. Average summer visibility: 54 miles.

Sequoia-Kings Canyon National Parks in California. Average summer visibility: 39 miles.

All of these are right in the air current movements from major air pollutors it appears. Geeze, no scientic evidence that coal burning power plants and big city auto emissions cause pollution? This looks pretty scientific to me. Suppose if we looked straight out into space and visibility was only 17, 20, 24, 39 or even 54 miles, how many stars and planets would we see? Zero!
