Indoor Air Quality
What Should You Know?
According to the
Environmental Protection Agency (EPA), indoor air is
anywhere from 2 to 10 times more hazardous than outdoor
air. In fact, the EPA warns that the indoor air quality
is the United States' number one environmental health
problem. As a result of the toxic air we breathe, EPA
studies have shown that billions of dollars are spent
annually for medication to help Americans breathe or
cure their respiratory illnesses.
Information given at
the First Annual Air Quality convention sponsored by
EPA, April 1992, Tampa, Florida includes these facts:
- Eleven million
Americans have asthma.
- Twenty-eight
million have hay fever and other allergies.
- 20% of all
employees have a major illness related to indoor air
pollution such as allergies, asthma, autoimmune
diseases, etc.
- EPA estimates an
18% annual production loss to American business due
to poor indoor air quality.
- 40% of all
buildings pose a serious health hazard due to indoor
air pollution, according to the World Health
Organization.
- EPA says high
levels of formaldehyde cause cancer .
- Scientists now
recognize that pollutants, even at acceptable
concentration, combined together in an indoor
environment have a synergistic negative effect.
Every year at least
6,000 new chemical compounds are developed. Many are
used indoors every day, at home and at work. Add to
these pollutants the mold, mildew, bacteria, viruses,
tobacco smoke, grease, pollen, dirt, asbestos, lead and
numerous other contaminants that can affect our
breathing and our health. Then allow them to circulate
in today's nearly airtight indoor environment. No wonder
our indoor air is, on average, two to ten times as
polluted as the worst outdoor air.
Viruses and bacteria
that thrive in the ducts, coils, and recesses of
building ventilation systems have been proven to cause
ailments ranging from influenza to tuberculosis. Some
HVAC systems have been found to contain up to 27 species
of fungi.
Other facts about the hazardous nature of our air
include:
- Asthma cases have
increased by more than 100% since 1976.
- About 1 in 9
children now have asthma.
- Death rates due to
asthma have tripled, and quintupled in children ages
5 to 9, since 1976.
- Hospitalization
rates and doctor visits are still continuing to
increase dramatically.
- According to the
American College of Allergies, 50% of all illness is
aggravated or caused by polluted indoor air.
- Today's homes and
buildings are built air-tight, and contain a long
list of pollution sources. As a result, nature's
air-cleansing agents such as ozone and negative ions
are kept out, while contaminants are kept in.
- A recent study
found that the allergen level in super-insulated
homes is 200% higher than it is in ordinary homes.
- According to
Scientific America, a baby crawling on the floor
inhales the equivalent of 4 cigarettes a day, as a
result of the out gassing of carpets, molds,
mildews, fungi, dust mites, etc.
- Most people spend
well over 90% of their time indoors. In which case,
indoor air is going to impact our health far more
than outdoor air.
- The EPA informs us
that 6 out of 10 homes and buildings are "sick",
meaning they are hazardous to your health to occupy
as a result of airborne pollutants.
Should you be concerned about Indoor Air Quality?
Here are 5 reasons why
indoor quality could be making your sick:
- It is now widely
recognized that most people spend more than 90% of
their time indoors. Because most of us spend so much
time inside, indoor pollution concentrations, even
if they are uniformly lower than outdoor levels,
make a significant contribution to our average
exposure over a day, week, month, or year.
- Modern indoor
environments contain a complex array of potential
sources of air pollution, including synthetic
building materials, consumer products, and dust
mites. Airborne emissions also occur because of the
people, pets, and plants that inhabit these spaces.
Efforts to lower energy costs by reducing
ventilation rates have increased the likelihood that
pollutants generated indoors will accumulate.
- Monitoring studies
inside buildings and vehicles have consistently
found that concentrations of many air pollutants
tend to be higher indoors than out. Indoor air has
been shown to be a complex mixture of chemical,
biological, and physical agents.
- Complaints about
inadequate indoor air quality and associated
discomfort and illness are a burgeoning problem in
our society. Reports of illness outbreaks among
building occupants, particularly office workers,
with no secondary spread of illness to others
outside the building with whom affected individuals
come into contact have become commonplace. EPA
classifies these reports into two general
categories: building related illnesses and
sick-building syndrome.
- Exposures to many
indoor air pollutants are known or suspected to
occur at levels sufficient to cause illness or
injury. Scientific evidence suggests that
respiratory disease, allergy, mucous membrane
irritation, nervous system effects, cardiovascular
effects, reproductive effects, and lung cancer may
be linked to exposures to indoor air pollutants.
