Did you know that…
Toxic mold can
seriously damage your lungs and central nervous system?
The
toxic black mold
Stachybotrys produces very potent chemicals that can cause brain
fogginess, tremors, and memory problems,
while Aspergillus mold
can cause cancer. Other molds produces
allergens that can trigger allergic reaction,
chronic sinusitis, and
asthma attacks.

Dampness and Inadequate Ventilation are Two Causes
of Microbial Pollution
From the World Health Organization
in its report WHO Guidelines for Indoor
Air Quality: Dampness and Mould,
published July 16, 2009
The presence of many
biological agents in indoor environments
is attributable
to dampness and
inadequate ventilation. Excess moisture on almost all indoor
materials leads to growth of microbes,
such as mould, fungi and bacteria, which
subsequently emit spores, cells,
fragments and volatile organic compounds
into
indoor air. Moreover,
dampness initiates chemical or biological degradation of materials,
which also pollute indoor air. Dampness has therefore been suggested
to be strong, consistent indicator of
risk of asthma and respiratory symptoms
(e.g. cough and wheeze). The health
risks of biological contaminants of indoor
air could thus be addressed by
considering dampness as the risk indicator.
Several widely acknowledged global
trends contribute to the conditions associated
with increased exposure to dampness and
mould:
►energy
conservation measures
that are not properly implemented (tightened
building envelopes, ventilation
deficits, improper insulation);
►urbanization (migration, building type
and density, urban degradation, housing
availability and
social inequity);
►climate
change (increasing
frequency of extreme weather conditions,
shifting
of
climate zones); and
►the quality and globalization of
building materials and components,
construction
concepts and
techniques.
These conditions increase the risks of
adverse health effects due to biological
contaminants of indoor air.
Airborne Mold
Spores (colony-forming units)
The airborne concentrations of viable fungi in indoor environments
are usually in the order of a few to several thousand colony-forming units (CFUs)
per cubic metre of air. In a given space,
concentrations of fungi are highly variable and depend on such factors as:
climate and season, type of fungus, construction, age and use of the
building, and ventilation rate. They also depend largely on the sampling and
analytical methods used, making valid comparisons between studies difficult.
