Indoor Air Quality (IAQ)

Materials used in building construction and conditions resulting from property damage, or even poor maintenance and upkeep, can result in indoor air pollution that could jeopardize a person's health. Many of the sources of Indoor Air Quality (IAQ) problems (i.e. formaldehyde, mold, radon, etc.) can be easily prevented and corrected by simple measures. Therefore, to help homeowners and business owners recognize and correct problems they may be experiencing, the following sources have been pulled together for easy access to useful information and answers to solve indoor air pollution. The information consists of guidance on most IAQ issues and associations of professional consultants should these services be desired or needed. Authorization and resources do not allow the MDEQ to visit homes and businesses to test for indoor pollution, but the agency is striving to be of assistance through the information it is making available here.

    Hide details for InsulationInsulation

    Symptoms from Fiberglass will typically go away after being removed or encapsulated. Fiberglass is not regulated and is widely used, but should not be breathed. There are some alternatives to fiberglass insulation (such as polyester and sheet foam). One technical paper concluded that wet spray-applied cellulose insulation (typically 30-40% water), when used in the walls of indoor environments, can become very moldy and result in unacceptable risk to occupants. It is recommended that fiberglass insulation be kept neatly contained (not hanging out) and use proper personal protective equipment to avoid exposure during installation or maintenance activities. Replace ceiling panels and repair disconnected ventilation ducts if needed.

    Hide details for MoldMold
    Hayfever-like symptoms such as stuffiness, throat irritation, coughing or wheezing, eye irritation, or, in some cases, skin irritation may be the result of a high concentration of mold spores. In worse cases Mycotoxins from molds has been linked to symptoms like headaches, nasal irritation, dizziness, fatigue, and nausea.

    Mold needs water and a food source (building materials) to grow. If one removes the water and moisture and keeps it dry, the mold cannot grow.

    Note on Mobile homes.
    Water may leak from the metal siding or roof (those that do not have shingles). Any exposed nail or screw in metal siding should be sealed so water does not seep into the wall cavities. Some walls have no barrier between the outer metal siding and inner dry wall sheeting to resist moisture. If a leak is suspected, it may be worthwhile to check the inner wall cavity for mold and correct any problems as soon as possible.

    U.S. Surgeon General Health Advisory

    "Indoor radon gas is the second-leading cause of lung cancer in the United States and breathing it over prolonged periods can present a significant health risk to families all over the country.  It's important to know that this threat is completely preventable.  Radon can be detected with a simple test and fixed through well-established venting techniques."  January 2005
