Sources of Indoor Air Contaminants

Source: OSHA
A wide variety of substances are emitted by building construction materials and interior
furnishings, appliances, office equipment, and supplies, human activities, and
biological agents.

For example, formaldehyde is emitted from various wood products, including particle
board, plywood, pressed-wood, paneling, some carpeting and backing, some furniture and
dyed materials, urea-formaldehyde insulating foam, some cleaners and deodorizers, and from
press textiles. Volatile organic compounds, including alkanes, aromatic hydrocarbons, esters,
alcohols, aldehydes, and ketones are emitted from solvents and cleaning compounds,
paints, glues, caulks, and resins, spray propellants, fabric softeners and deodorizers, unvented
combustion sources, dry-cleaning fluids, arts and crafts, some fabrics and furnishings,
stored gasoline, cooking, building and roofing materials, waxes and polishing compounds,
pens and markers, binders and plasticizers. Pesticides also contain a variety of toxic organic

Building materials are point sources of emissions that include a variety of VOCs (Table

Some of these materials have been linked to indoor air quality problems. The
probability of a source emitting contaminants is related to the age of the material. The newer the
material, the higher the potential for emitting contaminants. These materials include adhesives,
carpeting, caulks, glazing compounds, and paints [Ex. 4-33]. These materials, as well as
furnishings can act as a sponge or sink in which VOCs are absorbed and then re-emitted later.

Appliances, office equipment, and supplies can emit VOCs and also particulates [Ex.
4-33]. Table III-2 lists the many contaminants that can be emitted from these point sources.
There is an indirect relationship between the age of the point source and the potential rate of
contaminant emission [Ex. 4-33].

Emissions from equipment, such as computers, will decrease over time compared to
emissions from equipment that continually use chemicals. Emissions from such equipment (e.g.,
laser printers) that use chemicals continually, will obtain a steady state concentration
dependent upon the chemicals used and frequency of equipment use.

So You Like To Drink Coffee?

A cup of coffee is filled with chemicals.
They've identified a thousand chemicals in a cup of coffee. But we only found 22
that have been tested in animal cancer tests out of this thousand. And of
those, 17 are carcinogens. There are 10 milligrams of known carcinogens in
a cup of coffee and that's more carcinogens than you're likely to get from
pesticide residues for a year!

Smoking Linked to Hangnails

Well, not really.  At least, not yet.  But the nannies will have you believing it's possible if and when they decide to tell you so.  In the meantime, have a look at other illnesses/connections they have linked to smoking besides lung cancer and heart disease:

Cerebral Hemorrhage
Early Menopause
Hearing Loss
Seat Belt Use

Indoor Environments Threaten Health

Most people are aware that outdoor air pollution can damage their
health but may not know that indoor air pollution can also have
significant effects. EPA studies of human exposure to air pollutants
indicate that indoor air levels of many pollutants may be 2-5 times,
and occasionally, more than 100 times higher than outdoor levels.
These levels of indoor air pollutants are of particular concern because it
is estimated that most people spend as much as 90% of their time

Over the past several decades, our exposure to indoor air
pollutants is believed to have increased due to a variety of
factors, including the construction of more tightly
sealed buildings, reduced ventilation rates to save energy,
the use of synthetic building materials and furnishings, and
the use of chemically formulated personal care products,
pesticides, and household cleaners.

In recent years, comparative risk studies performed by EPA and its
Science Advisory Board (SAB) have consistently ranked indoor air
pollution among the top five environmental risks to public health.
EPA, in close cooperation with other Federal agencies and the private
sector, is actively involved in a concerted effort to better understand
indoor air pollution and to reduce people's exposure to air pollutants in
offices, homes, schools and other indoor environments where people
live, work, and play.

Reported Cancer Risks

Okay, so you don't smoke or you've quit smoking or you avoid cigarette smoke like the plague.

That means you either made a conscious choice not to ever smoke (Good for you!  It's about the right of choice!),
practically guaranteeing yourself at least a 50% shot of never contracting a serious illness.


You gave up something you enjoyed because:

a) You didn't enjoy it anymore (good for you! It's because you wanted to. Not because you thought you "should."), practically guaranteeing yourself at least a 50% shot of never contracting a serious illness.

b) You thought you were supposed to even though you really enjoyed it but everyone kept telling you you should quit, practically guaranteeing yourself at least a 50% shot of never contracting a serious illness.


You think that by avoiding Environmental Tobacco Smoke (ETS) you're practically guaranteeing yourself at least a 50% shot of never contracting a serious illness.

While you are fooling yourself into actually believing you're practically guaranteeing yourself at least a 50% shot of never contracting a serious illness by doing any of the above let me burst your bubble.  Then consider this:  The greatest risk is not taking one.  In other words, if you enjoy something, that benefit outweighs the risk because there are no guarantees in this life.

The following lists contain REPORTED Cancer & Heart Disease Risks.  It's very important you understand the word "REPORTED."   It means that there have been news and medical journal articles that have "reported" there is or may be a link between these items and either cancer or heart disease.  Either they still stand or they have been debunked.  But once something has been "reported" it's a hard press to convince the public they have no reason to act in a "better safe than sorry" manner when in contact with these items...  such as the case of ETS.  Either way, what makes you think that avoiding smoking or ETS will keep you more safe when there are all these other reported risks you come in contact with during everyday living:

Reported in USA Weekend (Feb. 23-25, 2001) by Michele Hatty

Every day, one in four Americans grabs a fast-food meal.  But far fewer give any thought to the dangers of eating it.  In a new book, Fast Food Nation (Houghton Mifflin, $25), investigative journalist Eric Schlosser tells what really lurks between those sesame seed buns.  It ain't good.

Mad cow scares aside, your patty likely includes meat from not one steer but dozens, slaughtered and processed hastily by low-paid workers.  Result?  Animal waste in your burger.  Yuck.  And sanitation is little better inside the eateries, largely staffed by ill-paid, unhappy, careless teenagers, Schlosser says.  Among his other unappetizing findings:

"These foods are OK to eat now and then," says the author, whose own kids, ages 8 and 9, love Happy Meals.  "But they're not having them now."
