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.

    Note on mobile homes, travel trailers and cottages:
    Formaldehyde is a common ingredient in pressed-wood products, including particle board, and can cause eye, nose, and throat irritation, wheezing and coughing, fatigue, skin rashes, headaches, nosebleeds, and severe allergic reactions.. Formaldehyde levels are generally much higher in the warmer months. Good ventilation can dilute and reduce levels quite a bit.
