What are molds?
Molds are microscopic fungi that
need plant and animal matter in order to grow. It is estimated that
there are greater than 100,000 different species of fungi that exist
across the world. These thinly spun threaded organisms produce spores
that then allow them to spread themselves to different locations.
Spores can be spread in the air, through water, or even among insects.
Are molds bad for humans?
Toxic molds can be dangerous and even fatal for susceptible
individuals. However, the majority of molds pose little or
no health risks to humans. Household molds exist in colors such
as red, green, blue-green, brown and black. In fact, there
are only two types of household molds that are toxic---Stachybotrys
and Memnoniella. For more information on Stachybotrys,
refer to the web page of the same name to the left.
What are some of the common indoor
molds?
- Cladosporium
- Penicillium
- Alternaria
- Aspergillus
What does household toxic mold
grow on?
Toxic mold is often found in damp, moist, or wet places in or around
a house or building. Stachybotrys typically grows in damp
environments on materials that are high in cellulose and low in
nitrogen content. Examples include wallpaper, cardboard, ceiling
tile, cellulose insulation, and wood. If the black mold is growing
on materials that do not contain cellulose, it is probably not Stachybotrys.
What makes Stachybotrys
toxic?
Stachybotrys mold spores produce a poisonous substance called
mycotoxin. Specifically, these are known as trichothecenes. When
these spores are inhaled and ingested by a human, they can cause
many unpleasant, and even very serious, symptoms and conditions.
How can mold affect people?
Sensitized individuals (people who
are prone to the effects of molds) may exhibit symptoms such as
nasal stuffiness, eye irritation, or wheezing. Individuals with
serious allergies to molds may show signs of fever and shortness
of breath. People with chronic illnesses, such as obstructive lung
disease, may develop mold infections in their lungs.
Can Stachybotris cause
disease?
Stachybotrys is thought to be responsible for a potentially
fatal condition called acute idiopathic pulmonary hemorrhage. This
has only occurred in infants and individuals with impaired immune
systems. However, the spores can also cause problems for asthma
sufferers, as well as allergies and certain kinds of lung diseases.
Stachybotrys is also thought to be at least partially responsible
for causing adverse health effects such as headaches, lung infections,
fevers, abdominal pains, diarrhea and skin rashes.
Where are molds found?
Molds are found in virtually every
ecological niche and are found outside in nature and in homes and
buildings. They are most prevalent in areas that have moist or wet
climates. They are often found indoors in humid spaces such as basements
or showers. Some authorities believe as many as 50 percent of all
homes may have some level of Stachybotrys infestation.
What can be done to lower mold
exposure?
- Individuals who are prone to the
effects of mold should stay away from problem areas---humid, wet
conditions.
- Indoor humidity levels should
be kept below 40%.
- Air conditioning and/or a dehumidifier
should be used during humid months.
- Adequate ventilation should be
maintained.
- Add mold inhibitors to paints
before application.
- Bathrooms should be cleaned with
anti mold products.
- Moist indoor areas (bathrooms,
basements, etc.) should not be carpeted.
- Remove or replace previously soaked
carpets and upholstery.
How do I know if I have a mold
problem?
The presence of large mold manifestation can usually be seen or
smelled. Smaller infestations may require professional cleaning
or testing in order to detect.
