REGION: Inland air quality remains among worst in nation


Published: 25 April 2012 02:01 AM
San Bernardino and Riverside counties ranked among the worst in the nation for ozone pollution — again — in the American Lung Association’s annual State of the Air report.

The Inland region also had some of the country’s highest levels of fine-particle pollution, the tiny particles from diesel soot, wood smoke and chemical compounds from factory and vehicle emissions that work their way deep into the lungs and bloodstream.

But experts said Tuesday that the South Coast air basin, which includes the Inland region, had made great strides since the first report 13 years ago. Progress includes a 33 percent reduction in ozone since the 2000 report and some of the best air quality in that time period, said Bonnie Holmes-Gen, executive director of the American Lung Association in California.

Still, the state is the No. 1 most polluted in the country from ozone and particle pollution for the measurement period, 2008 to 2010. Nearly three-fourths of the California counties received failing grades for not meeting federal clean air standards.

“While we do have the worst pollution in the country, we need to take heart — progress has been made,” Holmes-Gen said.

In Riverside County, ozone days have dropped 30 percent since the 2000 report, from 159.7 unhealthful days to 111.3. The number of unhealthful days for fine-particle pollution has declined 53 percent, from 81.5 to 28.8, since the 2007 report. And the county’s annual-average particulate levels dropped 41 percent over six years.

In San Bernardino County, there was a 33 percent reduction in unhealthful ozone days since the 2000 report, from 189.5 to 127.8. Days of unhealthful fine-particle pollution have dropped 64 percent since 2007, from 24.3 to 6.3. And the annual fine-particle levels for the county decreased 40 percent from 2004 and earned a passing grade this year for the first time.

Pollution causes asthma, stunted lung development in children, respiratory infections, heart attack, strokes and premature death.

A panel of experts from the American Lung Association recommended that individuals insist on continuing the federal Clean Air Act, despite attempts in Congress to repeal it. The public also can drive less, choose low-emission vehicles and avoid burning wood in fireplaces, they said.

"Key Emissions Sources
- Mobile Sources (motor vehicles, diesel trucks and buses, off-road sources including construction equipment, ports, trains, etc.) are responsible for over 70% of smog forming emissions in California and about 20% of the fine particulate emissions in the state.
- Stationary Sources like oil refineries, electric utilities and manufacturing plants.
- Residential wood burning (significant contributor to wintertime particulate levels).
- Managed agricultural and forest burning is also a source of particulate pollution."

"According to the report, you can protect yourself from ozone particle pollution by avoiding high-traffic areas, reducing the use of fireplaces and wood-burning stoves and to not let anyone smoke indoors."

"One surprise was Fairbanks, Alaska. The city near the center of Alaska's vast and mostly empty territory recorded high scores in both types of particle pollution. Tailpipe emissions and wood smoke from the numerous stoves used for heating freeze in the sub-zero temperatures and hang around for weeks at a time. It's called ice smog."
• The Surgeon General has determined that there is no safe level of exposure to ambient smoke!

• If you smell even a subtle odor of smoke, you are being exposed to poisonous and carcinogenic chemical compounds!

• Even a brief exposure to smoke raises blood pressure, (no matter what your state of health) and can cause blood clotting, stroke, or heart attack in vulnerable people. Even children experience elevated blood pressure when exposed to smoke!

• Since smoke drastically weakens the lungs' immune system, avoiding smoke is one of the best ways to prevent colds, flu, bronchitis, or risk of an even more serious respiratory illness, such as pneumonia or tuberculosis! Does your child have the flu? Chances are they have been exposed to ambient smoke!
