...PM-10 HIGH POLLUTION ADVISORY FOR MARICOPA COUNTY INCLUDING THE
PHOENIX METRO AREA THROUGH WEDNESDAY...

The Arizona Department of Environmental Quality (ADEQ) has issued a
PM-10 High Pollution Advisory for the Phoenix Metro Area through
Wednesday.

This means that ongoing stagnant weather conditions may result in
local PM-10 concentrations that pose a health risk. Adverse health
effects increase as air quality deteriorates.

Coarse particulate matter - also known as PM-10 - is an air
contaminant that can aggravate heart and lung disease conditions,
especially in older adults, children, and those with asthma. A
decrease in physical activity is recommended.

Consolidate your travel, stabilize loose soils, slow down or avoid
travel on dirt roads, reduce or eliminate fireplace use, and avoid
using gas-powered lawn equipment.

For details on this High Pollution Advisory, visit the ADEQ internet
site at www.azdeq.gov/forecast/phoenix or call 602-771-2300.
