Indoor air quality concerns have increased because energy conservation measures have required buildings to be “tighter.” This means polluted air has a harder time escaping buildings. Air pollutants may cause respiratory diseases, cancer and other health effects.
Sources of indoor air pollution:
- Combustion of oil, gas, and wood
- Tobacco smoke
- Deteriorated asbestos
- Wet or damp carpet or building components
- Personal care products
- Heating, ventilation, air conditioning systems
- Humidifiers and dehumidifiers
- Radon and other soil gasses
- Pesticides
Protect your indoor air quality
The American Lung Association has information on what to do to prevent indoor air pollution as well as what to do if you believe you already have a problem.
Test your home for radon
Radon is an odorless, colorless, tasteless gas that is produced by the natural decay of uranium and radium in the soil. Since radon is a gas, it can easily enter homes and other buildings through cracks in the foundation. Inside of homes, radon may become trapped and build up to dangerous levels. Exposure to radon increases your risk of developing lung cancer.
Two out of five homes in Dakota County have radon levels above the acceptable U.S. Environmental Protection Agency (EPA) guidelines. Find out how to test your home for radon (link to new page).
Be on the lookout for mold
Molds are simple, microscopic organisms, found virtually everywhere. Molds can be found on plants, foods, dry leaves, and other living material. Mold growths can often be seen in the form of discoloration, ranging in color from white to orange and from green to brown to black.
Health problems from exposure to mold can vary greatly depending on the person and the amount of mold in the home. The type of health symptoms that may occur include coughing, wheezing, nasal and throat conditions. People with asthma or allergies who are sensitive to mold may notice their asthma or allergy symptoms worsen.
Any damp conditions in a home can lead to the growth of mold, if not quickly and properly eliminated. These damp conditions can be caused by floods, leaky pipes, or excessive moisture in the home. Find out the basics of mold cleanup from the Environmental Protection Agency.
