Asthmatics troubled by smoky skies

Smoke from the Topanga Fire blanketed the skies from Simi Valley to the Channel Islands on Thursday, choking residents in the path of the flames and irritating asthma sufferers in the San Fernando Valley and elsewhere in the Los Angeles Basin.

Fine particles and soot from burning vegetation can be inhaled and swallowed, tickling the throat and nose and stinging the eyes.

The smoke is particularly rough on those with respiratory problems, making it more difficult to breathe, causing chest pain and triggering asthma attacks.

Even healthy people were warned to avoid strenuous outdoor exercise if they can smell smoke or see ash.

"I certainly wouldn't go for a jog," said Mallory Ham, air pollution meteorologist with the Ventura County Air Pollution Control District.

"We just want people to pay attention to the air-quality forecasts and smoke advisories. With the air quality index this high, we want people to adjust outdoor activities. If you're an asthmatic, you should just stay indoors."

Schools in San Fernando Valley and surrounding areas kept the windows closed and the students inside because of the thick, smoky air.

"It's tough for everybody. It's like a rainy day, usually schools have planned activities," said Karen Maiorca, director of nursing for the Los Angeles Unified School District.

"Any kind of exercise in the smoke is going to cause problems."

Burning brush and vegetation creates microscopic particles that are 30 times thinner than a human hair. The nose and upper airways usually filter out the larger particles, but the fine particles travel deep into the lungs and can enter the bloodstream.

Studies have linked high levels of fine particulate matter with increased rates of heart attacks and emergency room visits.

"People should use good common sense," said Keith Duval, compliance manager for Ventura County APCD. "If they're struggling with breathing or feel heaviness in the chest, or irritation of sinus and eyes, there's a good chance they are being affected by smoke."
