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, links to home testing kits, 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. mold mold mold mold mold mold mold mold mold.

MDEQ enforces rules for building demolitions and renovations; however, this does not include residential housing (except for apartment buildings with four or more units, projects with multiple residential buildings at a site, residential installations, or some larger projects). The MDEQ asbestos program provides compliance inspections for building renovations and demolitions to comply with National Emission Standards for Hazardous Air Pollutants (NESHAP), and also for nonprofit schools to comply with the Asbestos Hazard Emergency Response Act (AHERA). Symptoms of Asbestosis will often take 15-30 years after exposure conditions before they appear. Asbestos fibers are about 1/100th the thickness of human hair and cannot be seen without the aid of a microscope. Avoid damaging asbestos containing materials by grinding, sanding, sawing, etc. If asbestos containing materials in your home must be disturbed, consult your local yellow pages for a qualified contractor. Contractors working on nonresidential buildings must be certified by the MDEQ certification branch. A list of certified inspectors and contractors can be obtained from MDEQ.

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.
A few residents have complained about mold growth in their trailers; some of these were less than five years old. The growth was due to water leaking from the metal siding or roof (those that do not have shingles). Any exposed nail or screws in metal siding should be sealed so water does not seep into the wall cavities. Some walls have no barrier to resist moisture between the outer metal siding and inner dry wall sheeting. 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
