Odds Are, You're Breathing Bad Air

Welcome, sulphur dioxide,
Hello, carbon monoxide,
The air, the air is ev'rywhere.

- from the 1968 musical "Hair," lyrics by James Rado & Gerome Ragni

May 1, 2002 -- If you're an American, you're probably breathing bad air. For the third straight year, more than half of U.S. residents live in areas with dangerous smog.

The finding comes from the 2002 edition of the American Lung Association's annual State of the Air report. The bottom line: of the 678 U.S. counties monitoring air, nearly 400 get an "F" grade from the ALA. The failing grade means that these areas had levels of ozone -- a major ingredient in smog -- that made the air unhealthy to breathe for at least nine days.

Part of every year's State of the Air message is a ranking of the best and worst air in the nation. Here are the 10 most polluted urban areas:

  1. Los Angeles (Riverside/Orange counties)
  2. Bakersfield, Calif.
  3. Fresno, Calif.
  4. Visalia-Tulare-Porterville, Calif.
  5. Houston-Galveston-Brazoria, Texas.
  6. Atlanta
  7. Merced, Calif.
  8. Knoxville, Tenn.
  9. Charlotte-Gastonia-Rock Hill, NC-SC
  10. Sacramento, Calif.

And, in alphabetical order, here are the 11 urban areas with the least air pollution:

  • Bellingham, Wash.
  • Colorado Springs, Co.
  • Duluth-Superior, Minn.-Wisc.
  • Fargo-Moorhead, N.D.-Minn.
  • Flagstaff, Ariz.
  • Honolulu, Hawaii.
  • Laredo, Texas.
  • Lincoln, Neb.
  • McAllen-Edinburg-Mission, Texas
  • Salinas, Calif.
  • Spokane, Wash.

So which people are most at risk? Children, of course, and people with chronic lung diseases. But you're not off the hook if you're healthy. Athletes and people who work outdoors are also at increased risk of lung damage from air pollution, says Norman H. Edelman, MD. Edelman is the ALA's scientific consultant and is vice-president and dean of the SUNY-Stony Brook School of Medicine.

"We've still got a big problem. I get very frustrated," Edelman tells WebMD. "It is personal for me. I take care of a lot of asthma patients. They tell me when they can breathe and when they cannot. And very often they cannot."

This year, Edelman and the ALA want you to help. The public-health organization is asking people to write to their elected representatives and to President Bush to demand enforcement of existing clean-air regulations. For the first time, the ALA is providing an easy way to write these letters at their web site, lungusa.org.

"The EPA has adopted a set of more stringent rules, but they haven't put them into force. For us that is a big issue," Edelman says. "If the EPA would enforce their new standards we would be in good shape. They have not done so."

Why support enforcement of existing regulations when President Bush has just announced his "Clear Skies" initiative?

  • Earlier this year, the U.S. Environmental Protection Agency's director of regulatory enforcement quit in frustration. He cited huge cuts in enforcement staff and claimed that the White House and the Department of Energy have hampered ongoing enforcement actions.
  • Enforcing the Clean Air Act would reduce power-plant emissions -- and do it years faster -- than the "Clear Skies" initiative.

Meanwhile, you can do a lot to protect yourself -- and your community -- from air pollution. Here are some tips:

  • Fill gas tanks after dusk. Pumping gas releases chemicals that generate ozone in daylight.
  • Keep your car in good repair.
  • Use mass transit -- or walk -- whenever you can. Cars are a major source of air pollution.
  • Consider buying an electric car for short trips or for travel to mass transit parking lots.
  • If you run or walk for exercise, do it in the morning when pollution levels are low.
  • On very bad air days, don't exercise outdoors.
  • If you suffer from asthma or chronic lung disease, stay indoors and use your air conditioner on very bad air days. Ask your doctor about taking extra medicine to prevent complications on these days.
