Outdoor Air Quality
Outdoor air pollutants can affect health. They can cause short-term symptoms like shortness of breath or coughing. They can also play a role in causing diseases like asthma or respiratory illnesses.
Dane County Air Quality
The Environmental Protection Agency (EPA) measures air quality. The highest rating they give is “good,” and most days our air quality is at this level.
- Dane County air quality is consistent. Almost 80% of air quality measurements in the past 10 years were at the “good” level.
- When we have had poor air quality, the primary causes were high levels of ozone or fine particulate matter.
- You can find other information on the Healthy Dane Dashboard.
Sources of Air Pollutants
There are many things in the air we breathe that cause pollution. In Dane County we are mostly concerned with ozone and particulate matter.
- Ground level ozone is created when exhaust from cars and businesses mixes with other chemicals in the air. Breathing it can cause health problems. This mostly occurs during sunny and warm conditions, like in summer.
- Particulate matter is tiny pieces of dust, dirt and other materials in the air we breathe.
- Breathing particulate matter can be bad for your heart and lungs.
- When there is a lot of it, it can make the air look dirty, hazy, or brown.
Other Air Pollutants
- Gas and diesel vehicles produce air pollutants like benzene, formaldehyde, acetaldehyde and 1,3-butadiene.
- Wood burning stoves and fireplaces contribute to indoor and outdoor air pollution. They can affect your health and your neighbor's health. Burning wood improperly can reduce air quality in our community .

- Air pollutants from places outside of Dane County can also affect our air quality. Many air pollutants can travel long distances. They can cause ozone or fine particulate problems in areas with low amounts of air pollution.
Outdoor Air Quality and Your Health
Breathing in ozone or particulate matter can cause:
- throat irritation
- shortness of breath
- chest pain
- asthma attacks
- worsening of other health conditions.
Air pollutants can also play a role in causing asthma, other respiratory illnesses, and cardiovascular diseases.
Older adults, children, and people with certain health conditions like asthma, emphysema, and heart and lung conditions should be careful when air quality is poor.

Take Action When Air Quality is Poor
If the air quality index is orange, reduce physical exertion and the amount of time spent outside.
If the air quality index is red or worse, avoid prolonged or heavy exertion. If you use an inhaler, keep it with you.
