What Is Mold?
Molds are simple,
microscopic organisms whose purpose in the ecosystem is to break down
organic materials. They can be found wherever there are organic
materials and moisture, which are the necessary ingredients for mold
growth. Molds are found both indoors and outdoors, and in any area of
the country. Some are visible, some are not.
Except in structures where all of the incoming air is cleaned, there is
never going to be a “mold-free” condition. Therefore, when checking a
house for mold, the intent is to have the indoor mold condition equal to
or lesser than the outdoor condition. Mold screening of the indoor and
outdoor conditions determine if an indoor mold problem exists and what
types of molds are growing indoors.
Mold spores generally enter a home on air currents, clothing, shoes and
house pets. They thrive particularly well on cellulose materials such as
wood, drywall, ceiling tiles and carpet. When a mold spore comes into
contact with a suitable surface, it germinates and begins to grow. Each
mold colony (mycelium) then produces millions of microscopic spores
within a few days, and continues to grow as long as sufficient moisture
is present.
A small portion of mold may be visible on the surface of a material.
However, it is this part of the mold that usually releases the largest
amount of reproductive spores. These spores facilitate further
germination and present the potential health threat we hear so much
about today. According to the New York City Department of Health’s
Facts about Mold, (February 28, 2001), mold spores can be released
into the air when mold material becomes damaged or disturbed. Homeowners
are exposed to mold when they inhale the spores, handle moldy materials
or accidentally ingest mold. Molds can also produce mycotoxins, which,
according to the EPA, can potentially produce serious health effects.
