...OZONE AND PM-10 HIGH POLLUTION ADVISORY FOR PINAL COUNTY
WEDNESDAY...

The Arizona Department of Environmental Quality (ADEQ) has issued an
Ozone and PM-10 High Pollution Advisory for Pinal County Wednesday.

This means that forecast weather conditions combined with existing
ozone levels are expected to result in local maximum 8-hour ozone
concentrations that pose a health risk. Adverse health effects
increase as air quality deteriorates.

Ozone is an air contaminant which can cause breathing difficulties
for children, older adults, as well as persons with respiratory
problems. A decrease in physical activity is recommended.

You are urged to car pool, telecommute or use mass transit.
The use of gasoline-powered equipment should be reduced or done late
in the day.

Also, 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.
