Indoor Air Quality

We spend more time indoors than outdoors.  Due to this behavior, the air inside our homes can drastically affect our health.  As new homes are built, the air exchange rate lessens due to better insulation and construction methods.  There is not much leakage to the outside or allowance of outdoor air to enter the house.  Homes running air conditioners or heaters constantly do not allow for fresh air to enter and replace the old air.  Lead dust, carbon monoxide, and radon are some of the indoor air quality issues that can cause health problems.


Asbestos is the name given to a group of minerals naturally occurring in the environment as bundles of fibers that can be separated into long, durable threads.  The fibers are resistent to heat, fire, and chemicals and do not conduct electricity making asbestos popular for use in a wide range of products, including building materials, automotive parts and heat-resistant fabrics (IDEM, 2012).  Asbestos becomes a problem when the fibers begin to break apart.  The fibers are inhaled and, after a period of time, can cause cause cancer and mesethelioma.


Asthma is a respiratory disease caused by environmental triggers, such as mouse urine, feces or hair.  These triggers cause the airways of the lung to tighten preventing a person from breathing easily.  Other triggers include urine, feces and body parts of cockroaches and pet dander.


Carbon monoxide is a colorless, odorless gas that can cause death if too much is inhaled.  The causes of carbon monoxide poisoning are malfunctioning gas stoves and furnaces, running vehicles in attached garages, and kerosene heaters.  Carbon monoxide detectors should be placed on each floor of your house.  Check the batteries regularly to ensure the detectors are functional.


Environmental tobacco smoke or secondhand smoke can cause serious health effects to people living in a home of a smoker, especially children because their lungs are still developing.  Secondhand smoke contains more that 4,000 substances, several of which are known to cause cancer in humans or animals (EPA).


We are exposed to formaldehyde in our homes from wood-pressed products, gas stoves, kerosene heaters, and secondhand smoke.  The highest exposure comes from the glue in wood-pressed products.  "Exterior-grade" wood-pressed products should be purchased for use in your home.

Mercury is a naturally-occurring element that is found in air, water and soil.  It exists in several forms:  elemental or metallic mercury, inorganic mercury compounds, and organic mercury compounds.  Elemental or metallic mercury is a shiny, silver-white metal and is liquid at room temperature.  If heated, it is a colorless, odorless gas.  Exposures to mercury can affect the human nervous system and harm the brain, heart, kidneys, lungs, and immune system.  The most common way we are exposed to mercury is by eating fish or shellfish that are contaminated with mercury.  Another less common exposure to mercury that can be a concern is breathing mercury vapor.  These exposures can occur when elemental mercury or products that contain elemental mercury break and release mercury to the air, particularly in warm or poorly-ventilated indoor spaces.

  • This engorged American Dog Tick was pulled off a human.  To prevent tick attachment, wear light-colored clothing, long pants with the bottoms placed into the top of socks, and apply a DEET-product to your clothing.  Check your clothing and body after exiting a high grass or wooded area.
  • De-rimmed tires breed mosquitoes and can provide drinking water for rats.  Culex species, ones that can carry WNv, and Ae. triseriatus, carrier of LaCrosse Encephalitis, use tires as a habitat when in the larval form.  The sun heats the black rubber allowing for increased mosquito production, even when it is cool out.  Tires should be properly disposed of or covered to prevent mosquito breeding.

Did You Know?

Mosquitoes only need about a 1/4 inch depth of water to go through their life cycle. They can emerge from bottle caps as adults.
