Sources of Air Pollutants

There are many things in the air we breathe that cause pollution.  Some contaminants of concern for our area are 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

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 particulate matter, it can make the air look dirty, hazy, or brown.


Other 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.  See the following link for more information:  Outdoor Wood Boilers (Water Stoves) | Wisconsin Department of Health Services


Outdoor Air Quality and Your Health

Breathing in ozone or particulate matter can cause throat irritation, shortness of breath, coughing, wheezing, chest pain, asthma attacks, and worsening of other health conditions.  Air pollutants can also play a role in causing asthma, other respiratory illnesses, and cardiovascular disease.  See the following link for more information:  Outdoor wood boilers | | Wisconsin DNR
