Wildfire smoke poses additional health risks in Los Angeles

Experts have warned residents of Los Angeles and its surrounding areas of the dangers of exposure to wildfire smoke as several fires continue to blaze across the region.

Although the air quality index, which measures ozone and fine particulate matter, is poorest just near the fires, the air in the entire LA basin may be unsafe to inhale, according to a news report from NPR.  The risks have prompted the closures of many schools and businesses.

Exposure to fine particulate matter at an AQI of 100 to 500 in some areas can impact the health of a healthy individual and lead to emergency room visits for those with preexisting conditions such as asthma and chronic obstructive pulmonary disease. Recent research has also shown that wildfire smoke can exacerbate cardiovascular diseases and increase the risk of developing dementia.

Because the LA wildfires are burning trees, brush, houses and cars, many of the toxic materials included in the smoke can have profound consequences for those exposed — particularly children, older adults, pregnant women and firefighters.

The experts advised individuals in the region to remain indoors if possible, ensure the windows are closed tight, turn on an air filter, and wear an N95 mask when going outside.
