Molds are microscopic fungi
that live on organic materials such as; food, plants, paper and some
building materials. In order to grow and survive, mold needs a food
source, water, oxygen and a temperature range, generally, from 40°F
to 100° F. Molds secrete a digestive fluid that decomposes organic
materials thus creating a nutrient source (food). While Molds
prefers a damp surface, they can survive in areas with high humidity
and no direct water source.
Molds are naturally occurring
organisms in the environment and are present everywhere. The
reproductive organisms of the mold are called spores. Mold spreads
through the dissemination of microscopic spores that can travel on
currents of air. They will attach themselves to organic materials
such as plywood, carpet and sheet rock and to inorganic materials
such as; concrete, metal or glass. Mold cannot get nutrients form
these inorganic materials but it can survive there provided that it
has a food source.
Spores can be inhaled,
ingested and absorbed through the skin. Spores can cause
allergy-like
symptoms in people ranging from minor to severe, depending
upon the amount of mold and the type of mold present. People with
lowered immune systems such as infants, young children, the elderly
and those with asthma and allergies are particularly susceptible to
the effects of mold. Certain molds create strong chemicals called
mycotoxins. Mycotoxins in such molds as penicillium can be used in
medicines to kill bacteria. Unfortunately, other mycotoxins can cause illness in humans. Several factors
determine the extent of illnesses caused by mycotoxins. These
factors include; the type of mold, the amount of mold, and how each
individual immune system protects a person against these chemicals.
If you suspect the presence
of mold in your office, building or residence, a trained
professional should be hired to investigate the problem.
