Mold is a decomposer. Its role in the environment is to consume organic materials and return carbon, which is found in all living matter, back to Earths crust. Water and organic matter are absolutely essential for the existence of mold. We can control mold growth and mold spore levels in buildings by keeping interiors and organic materials in them clean and dry. Health authorities suspect that all mold spores are allergens to some degree. In high enough concentrations and sufficiently long exposure times, regardless of species, mold spores can, in theory, trigger a reaction. Some molds trigger allergic reactions more readily at lower exposure levels. Anyone with asthma, allergies, or weakened immune systems is most susceptible to adverse reactions. Mold is only an environmental problem when it grows, amplifies, and gets out of control. Small amounts of mold growth on indoor surfaces, a few square inches for example, are not likely to pose a problem. It is only when spores are released to the air that the risk increases. As mold on an interior surface begins to die, it releases spores as part of normal reproduction. The longer mold is allowed to grow, the more likely it becomes that sensitizing or allergen spores will be released into the air. Molds obtain nourishment from organic materials such as paper and wood products (cellulose), natural fibers, foods and many soils. When clean and free of foreign organic matter, synthetic carpet materials do not support mold growth. Water is essential for mold growth and water leaks are often associated with mold growth. Once mold growth has begun, high humidity at the surface of an organic food source may be all that is needed to sustain the growth. Clean and dry = no mold! Fungi can survive over a broad temperature rang ...
