The Arizona Department of Environmental Quality has issued a PM-10 health watch for Tuesday.
The health watch comes after Monday's particulate matter-10 high pollution advisory, which was sparked by blowing dust caused by winds up to 45 mph in the Valley.
A high pollution advisory is issued when particulate matter levels are expected to exceed federal standards. A health watch is issued when levels are expected to approach federal health standards.
During a health watch, the public is asked to:
Avoid activities that generate dust, such as driving on dirt roads.
Stabilize loose soils.
Eliminate fireplace and wood stove use.
Drive as little as possible: car pool, use public transit or telecommute. For information on transportation alternatives, visit Valley Metro: www.ValleyMetro.org or call (602)253-5000.
Avoid using gas-powered lawn and garden equipment.
