Mold and DampnessIndoor air quality IAQ is the air quality within and around buildings and structures. IAQ is known to affect the health, comfort and well-being of building occupants. Poor indoor air quality has been linked to sick building syndrome , reduced productivity and impaired learning in schools. IAQ can be affected by gases including carbon monoxide , radon , volatile organic compounds , particulates , microbial contaminants mold , bacteria , or any mass or energy stressor that can induce adverse health conditions. Source control, filtration and the use of ventilation to dilute contaminants are the primary methods for improving indoor air quality in most buildings. Residential units can further improve indoor air quality by routine cleaning of carpets and area rugs. Determination of IAQ involves the collection of air samples, monitoring human exposure to pollutants, collection of samples on building surfaces, and computer modelling of air flow inside buildings.

For more than a decade, mold has been in the news. People are talking about the effect on population health and damage to the building. But what are the risks and issues? A number of agencies have guidelines that include protective measures for mold remediation and cleaning. The available science on molds and their potential health effects remains under study, but considerable progress has been made. The U.
Frequently asked questions FAQ about dampness and mold that we have received over the years. Molds are simple, microscopic organisms, present virtually everywhere, indoors and outdoors. Molds, along with mushrooms and yeasts, are fungi and are needed to break down dead plant and animal material and to recycle nutrients in the environment. Because molds grow by digesting organic material, they gradually destroy whatever they grow on. Molds can grow on surfaces or objects in buildings. Mold growth on surfaces can often be seen in the form of discoloration: frequently white, gray, brown, or black but also green and other colors. They may be visible or, if inside walls or building structures, not visible to you.
Truth About Mold. Research Papers. Government agencies, mainstream medical organizations, teaching hospitals, allopathic physicians, insurance companies, defense attorneys, bought-and-paid-for defense witnesses and other naysayers will tell you that mold isn't harmful or that it only causes allergic reactions or it effects only immune-compromised individuals. That is false and misleading. There are thousands of research papers regarding the health effects of indoor contaminants.
Damp buildings often have a moldy smell or obvious mold growth; some molds are human pathogens. This has caused concern regarding health effects of moldy indoor environments and has resulted in many studies of moisture- and mold-damaged buildings. Recently, there have been reports of severe illness as a result of indoor mold exposure, particularly due to Stachybotrys chartarum. While many authors describe a direct relationship between fungal contamination and illness, close examination of the literature reveals a confusing picture. Here, we review the evidence regarding indoor mold exposure and mycotoxicosis, with an emphasis on S. We also examine possible end-organ effects, including pulmonary, immunologic, neurologic, and oncologic disorders.
