ADEQ Issues High Pollution Advisory for Particulate Matter for Thursday,
PHOENIX (March 25, 2009) - The Arizona Department of Environmental
Quality has issued a High Pollution Advisory (HPA) for Thursday, March
26 for the Phoenix metropolitan area because of forecast weather
conditions that are expected to be conducive to unhealthy levels of fine
Particulate Matter 10 (PM10) microns and smaller.
The HPA is being issued because of anticipated winds with gusts of up to
35-40 miles per hour Thursday afternoon. The combination of winds and
loose, dry soil due to the recent lack of rainfall means a high chance
of blowing dust across the Valley for several hours on Thursday through
ADEQ recommends that children and adults with respiratory problems avoid
outdoor activities on Thursday and suggests that the general public
limit outdoor activity throughout the day. Due to the possibility of
reduced visibility because of dust, motorists should exercise caution.
In addition, the Maricopa County Air Quality Department has designated
Thursday to be a No-Burn Day for residential fireplaces, woodstoves and
outdoor burning devices.
Also, under state law, recreational use of off-highway vehicles (OHVs)
in Area A of the greater Phoenix area is prohibited. Local ordinances in
the Valley also limit the use of leaf blowers.
PM10 refers to particles that are 10 micrometers in diameter or smaller.
Once inhaled, these particles can affect the heart and lungs and cause
health effects, including irritation
of the airways, coughing, difficulty breathing, decreased lung function,
asthma, development of chronic bronchitis, irregular heartbeat, heart
attacks and premature death in people with heart or lung disease.
