The Maricopa County Air Quality Department has declared Friday the first "no burn" day of the winter pollution season due a health watch for fine particulate matter pollution issued by the Arizona Department of Environmental Quality. The burn ban will be in effect Friday for 24 hours, from midnight to midnight.
Air monitoring data shows an increase of fine particulate pollution, according to a news release. The biggest source is fireplace burning activity.
According to the release, wood smoke particles are too small to be easily filtered out by the nose or upper respiratory system. As a result, they get deep into the lungs.
During the burn band, residents may not use woodburning fireplaces, wood stoves, outdoor fireplaces or leaf blowers. It's also helpful if residents driver slower or not at all on unpaved roads and vacant lots.
