|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. |

Fireplaces, Wood stoves, Wood heaters, Wood boilers
The major pollutants released from these sources are carbon monoxide, nitrogen dioxide, and fine particles. Unvented kerosene heaters may also generate acid aerosols. (Recent regulatory requirements require wood boilers to be no closer than 100 ft from a residence).

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.
Household Cleaning Chemicals and Sprays
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.
