[5] _Mold and Moisture – Mold Remediation in Schools and Commercial

Buildings_ (http://www.epa.gov/mold/append_b.html) 07-05-2008

Moisture control is the key to mold control. Molds need both food and water

to survive; since molds can digest most things, water is the factor that

limits mold growth. Molds will often grow in damp or wet areas indoors.

(http://www.epa.gov/appcdwww/iemb/child.htm) 07-01-2008

Outbreaks of the fungi Stachybotrys chartarum (S. chartarum) are under

investigation for an association with the deaths of infants in Cleveland, Ohio,

and serious health problems in other areas of the U.S. Although not widely

found, Stachybotrys chartarum has been studied for the last 20 years. The follow

ing is documented. Chartarum produces toxigenic spores that are potentially

hazardous, especially when the air-conveyance system is involved.

[9] _Indoor Air Pollution: An Introduction for Health Professionals_

(http://www.epa.gov/iaq/pubs/hpguide.html) 06-30-2008

Indoor air pollution poses many challenges to the health professional. This

booklet offers an overview of those challenges, focusing on acute conditions,

with patterns that point to particular agents and suggestions for

appropriate remedial action.

Aflatoxin B1 is perhaps the most well known and studied mycotoxin. It can be

produced by the molds Aspergillus flavus and Aspergillus parasiticus and is

one of the most potent carcinogens known. Ingestion of aflatoxin B1 can cause

liver cancer. There is also some evidence that inhalation of aflatoxin B1

can cause lung cancer. Aflatoxin B1 has been found on contaminated grains,

peanuts, and other human and animal foodstuffs. However, Aspergillus flavus and

Aspergillus parasiticus are not commonly found on building materials or in

indoor environments.

Much of the information on the human health effects of inhalation exposure to

mycotoxins comes from studies done in the workplace and some case studies or

case reports._*_ (http://www.epa.gov/mold/append_b.html#Note:_) Many

symptoms and human health effects attributed to inhalation of mycotoxins have been

reported including: mucous membrane irritation, skin rash, nausea, immune

system suppression, acute or chronic liver damage, acute or chronic central

nervous system damage, endocrine effects, and cancer. More studies are needed to

get a clear picture of the health effects related to most mycotoxins.

However, it is clearly prudent to avoid exposure to molds and mycotoxins.
