not just L.A. any more. Three out of every four Americans now breathe air
so dirty it threatens the health of children, the elderly, and even outdoor
joggers.
The American Lung Association's annual State of the Air report card gave an F in air quality to nearly 400 U. S. counties a 15% increase since the previous report. And don't breathe a big sigh of relief if you don't live in a big city. Many of the regions that flunk healthyair standards are medium and small metropolitan areas.
"It is of concern to us because a large percent age of the counties in the U.S. are experiencing unhealthy air," said Norman H. Edelman, MD. "There are things we can do about it, and we have to be ever vigilant. It is bad for everybody but especially bad for people with chronic lung disease and people with asthma." Edelman, dean of the president for the SUNY-Stony Brook School of Medicine and vice president of the SUNY Health Science Center, serves as scientific consultant to the American Lung Association.
More than 141 million U.S. residents live in areas with unhealthy amounts of ozone in the air nine million more than last report. And that's only counting areas where ozone has been measured for at least three years. Nearly 60% of places where ozone is monitored get the failing grade.
The grading system is based on the number of days an area has ozone levels that are unhealthy for sensitive people, unhealthy for all people, or very unhealthy for all people. A score of 3.3 is a failing grade but places on the 10worst list are far worse:

tied with Raleigh Durham Chapel Hill, NC.
For people who like better air, there were 12 metropolitan areas without any badair days at all: Bellingham, WA; Colorado Springs, CO; Des Moines, IA; and Duluth, MN, got perfect scores two years in a row.
The rest of the cities making the good breathing list were:
1. FargoMoorhead,
N.D.MN;
2. FLagstaff,

3. Honolulu,
HI;
4. Laredo,
TX;
5. Lincoln,

6. McAllen

7. Salinas,
CA; and
8. Spokane,
WA.
But a small town is no guarantee of safe air. Small cities like Lancaster, PA, and Redding, CA, also have smogfilled air.
Jonathan M. Samet, MD, professor and chair of the department of epidemiology at Johns Hopkins University's Bloomberg School of Public Health, leads a research team that recently linked increases in air pollution to increased deaths in 20 U.S. cities. This research focused on tiny particles in air pollution but Samet says ozone is a similar danger.
"The evidence is suggestive that ozone also increases mortality in addition to the effect seen for particles," said Samet. "One of the main questions is the effect of ozone on large populations. The questions are about longterm effects."
Ozone is released when sunlight hits the fumes emitted by the fuelburning engines of diesel machinery, trucks, and, of course, cars. Researchers recently found that ozone and small particles of contaminants actually can constrict the circulation of blood in the lungs. But that's not all. When you breathe ozone, it can burn the sensitive lung tissue.
*(Some other thoughts I am adding to this article. Industry that does any fossil fuel burning including power plants and so forth cause the same fumes but in the case of Natural Gas Power plants, I personally was a intervenor in some California Siting cases, "CEC Docket #'s 98-AFC-1c, 98-AFC-3, & 00-AFC-1", and learned that one of the largest emissions they release is Formaldehyde which also causes the burning of the lungs without you knowing it. The particulate matter or PM of natural gas when burned is less than 1 micron in size which means that it can cause cellular damage and your cell will not trigger a immune response. The immune response begins to happen when your body detects your cells as foreign to the body and then a autoimmune response will occur. Once it has reached that stage you can not shut it off. Natural Gas is not clean energy or fuel as they have been advertising and in California that is against Voter Approved Proposition 65 to not inform people of this fact. I have in the past Informed PG&E of that fact but they have not conformed to what I told them. They continue to send out a Proposition 65 letter that does not say that on it. I thought you might like to know this since this article seemed to omit that fact.)
"It's like getting a superficial burn of your airways," Edelman says. "It can cause chest tightness, pain, and difficulty breathing it depends on how much you breathe in and how sensitive you are. But runners who run at high ozone levels, or even in normal kids who camp out, get more symptoms when ozone levels are higher."
What can you do about it?
"As individuals we can go inside, exercise in the morning rather than midday, keep children inside in unhealthy areas on unhealthy days, and make sure patients with emphysema and asthma live in environments and that really means air conditioning where they are protected," Edelman says. "As a people we can support stringent air standards and, most importantly, enforcement of these standards."
Over the past 20 years, ozone levels actually have gone down. But a new trend of increasing ozone now appears to be underway.
"I think if we had a public policy that encouraged use of fuel efficient cars we would then start to reduce air pollution again," Edelman says. "We went through this good period when everybody was concerned and conserving, but we have moved far away from that. Those SUVs we all drive are gas guzzlers."
