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

The Arizona Department of Environmental Quality (ADEQ) has issued a
PM-2.5 High Pollution Advisory for the Phoenix Metro Area on Tuesday
and Wednesday and has issued a PM-10 High Pollution Advisory for the
Phoenix Metro Area on Wednesday.

This means that ongoing stagnant weather conditions combined with
existing airborne fine and coarse particulate levels may result in
local particulate concentrations that pose a health risk. Adverse
health effects increase as air quality deteriorates.

Fine particulate matter – also known as PM-2.5 – 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, reduce or eliminate fireplace use, refrain
from outdoor burning, and avoid using gas-powered lawn equipment.
