Ozone Season

Oklahoma's ozone season runs from March to November, months where there is enough sunlight to promote ozone formation. Automobile combustion engines are one source of ozone precursor chemicals. For short trips, consider walking or cycling to your destination.

What will you do for Cleaner Air?
Reduce your smoke exposure: 1 - Stay inside with doors and windows closed, 2 - Run an air conditioner with a clean filter, 3 - Seek alternative shelter away from smoke, 4 - Don't rely on dust dust masks for protection; they don't trap fine smoke particles

Smoke from fires has air pollutants like particulate matter (PM) and ozone precursors that can cause or aggravate serious health conditions.

What is air quality?
The amount of pollution in the air from all sources - natural and human - defines the quality of the air we breathe.  Air pollution isn't limited to our cities; it can blow into any part of Oklahoma from neighboring states.

Why is it important?
Bad air quality can affect everybody's health.  It can have direct effects on the lungs, and it can worsen an existing condition, such as asthma.  Some people are more sensitive to air pollution than others.  These include young children who are growing rapidly and older adults who have reduced immune systems.
Poor public health also incurs economic costs for society, e.g., increased healthcare costs and loss of working days.  And a clean environment makes Oklahoma an attractive place to live, work and play: something we can all be proud of.

What does the Air Quality Division do?
Most importantly, we work to effectively protect the public health in Oklahoma.  We do this by:
