The Arizona Department of Environmental Quality (ADEQ) has issued a
PM-10 High Pollution Advisory for Nogales on Friday.

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.
