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

An episode of strong and gusty winds is forecast to generate
widespread blowing dust that 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.
