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.
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. 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?
