Dust Dangers: What Exactly is Dust, and Why Can it be so Dangerous?
by SixWise.com
Most people don't think about it when they don't
see it. It's only when it starts to coat every countertop,
every crevice, every surface in your home -- even though
you just got rid of it a couple of days earlier -- that
it really gets to you.
It's dust. Yes, it's inconvenient. It may make
you sneeze, and most of us are familiar with the common allergen,
dust mites. But did you know that the dust in your home could
actually contain toxic compounds? Things like flame retardants
and toxins from cigarette smoke are just a couple of examples
of the chemicals that could be in your household dust.
"Certain toxic chemicals, such as lead, pesticides,
polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons
(PAHs) are routinely found in household dust," says Andrea
Ferro, professor of civil and environmental engineering at
Clarkson University and an air quality researcher. "Simple
activities such as dusting and vacuuming generate or re-suspend
the pollutants into the air that we then breathe in."

Dust that collects in carpets can contain toxic chemicals
like lead, pesticides and PCBs. Leaving your shoes at
the door may help to reduce your risk.

What is Dust, Anyway?
Dust is the collective term used to describe the wide variety
of organic and inorganic particles that collect in our homes.
Here's an unpleasant thought: The majority of dust is
made up from shed skin cells. That's why the areas of
your home that are used most often also tend to have the most
dust. (Dust mites like to eat these skin cells.) Dust on mattresses,
bedding and sofas will contain a particularly large amount
of skin cells.
Says Larry Arlian, an internationally recognized expert on
dust mites, dust is a complex mixture of a lot of different
materials, and a lot of it is unavoidable.

Breakdown of Common Components in Household Dust
- Shed human skin cells
- Flame retardants like polybrominated diphenyl ethers
(PBDE)
- Paint particles
- Cigarette smoke (and its toxic byproducts)
- Pesticides
- PCBs (polychlorinated biphenyls)
- PAHs (polycyclic aromatic hydrocarbons)
- Fabric fibers from your clothes, carpets, upholstery,
etc.
- Sand and soil particles
- Plant and insect parts (When dust is examined under
a microscope, it is not at all unusual to spot ant
heads or other insect body parts, says Arlian.)
- Mold spores
- Pet dander and feathers
- Dust mites and their feces
- Viruses
- Rodent waste
- Construction debris (adhesives, sawdust, etc.)
- Pollen
- Bacteria
- Asbestos
- Heavy metals such as lead, cadmium and mercury

How is Dust Dangerous?
When you walk around or vacuum, dust particles are stirred
up into the air, and along with them come the slew of potential
toxic chemicals and other unsavory items like rodent waste
and insect parts. You may then breathe in these particles
or absorb them through your skin once they settle back down
onto a surface you touch.

Dust is mostly made up of shed human skin cells, but
it can also contain flame retardants, heavy metals and
toxic byproducts of cigarette smoke.

This is especially concerning if you have small children
or infants. Children who crawl and put their fingers in their
mouth can ingest 10 grams of dust per day. And, since they're
smaller than adults and their systems are still developing,
they are at a higher risk from contaminants.
Allergies, asthma, itchy eyes, coughing and runny noses aside,
the specific health effects of house dust depend on which
contaminants are in the dust, as well as the levels and how
long you have been exposed. In the case of flame retardants
(PBDEs), for example, which one U.S. study found were present
in every home they tested, they could affect brain development
and reproductive hormones.
And if you think simply inhaling dust isn't enough of
an exposure, the researchers found that two-thirds of the
PBDEs present in adults' bodies seem to be coming from
household dust. In the case of infants, some 90 percent of
their PBDE body level came from house dust.
How to Minimize Dust in Your Home
It's impossible to NOT have any dust in your home. The
key, however, is to keep dust, and therefore your risk of
illness, to a minimum.
Get rid of carpets: According to Arlian, one of the
best ways to reduce household dust is to get rid of carpets.
That's because they're a perfect place for dust
to cling to, and they even produce dust of their own (from
the fibers). Opting for hardwood floors with scattered rugs,
which should be washed in hot water weekly, is the optimum
dust-reducing choice.
Dust often and with the right tools: Arlian also noted
the importance of dusting horizontal surfaces regularly -- but
not just with an ordinary dust cloth. "People used to
dust with things like cloth diapers, and they just kind of
moved dust around," he said.

What's the optimum choice for dusting? The
PerfectClean line of mops, dusters, towels and more, which
are used by leading hospitals and other healthcare organizations.
Rather than just pushing dust around, or worse, stirring it
up into the air, PerfectClean's EasyGrip Mop and Flexible
Duster are made with positively-charged ultramicrofibers that
pick up everything in their path -- including dust and all
of its microscopic attachments. These ultramicrofibers are
so small at an astonishing 3 microns that they're even
smaller than most bacteria (each cleaning cloth contains over
300 miles of actual cleaning surface!). They pick up contaminants
either used dry or dampened with water -- no harsh cleaners
needed.
This is an important factor, as according to Ferro, "Many
pollutants don't just evaporate ... The chemicals may then
adhere to surfaces and carpets, but they may be released into
the air again when you vacuum your house or simply walk across
the carpet. In addition to the risk of breathing the chemicals,
touching the contaminated surfaces can lead to exposure through
the skin."
Choosing PerfectClean's ultramicrofiber cloths, mops
and wipes are by far the smartest choice -- and the most
economical since each cloth can be used over 100 times before
being replaced -- for dusting in your home.
Leave Dirt Outside Your Doorstep. 90% of all dirt
in the home is tracked in from the outside (and much of it
becomes dust inside the home). Doormats not only add aesthetic
appeal, but the right doormat (one designed with fibers that
truly capture dirt and liquids) is an important health and
wellness tool! Wiping your shoes thoroughly before entering
not only keeps the home visually more appealing, but far more
important, it really can dramatically reduce the amount of
dangerous dirt and dust in the home.
Use a High-Quality Air Purifier. According to many
leading health organizations including the American Lung Association
and the most respected health experts such as Dr. Morton Walker
and Jordan Rubin, with the growing knowledge of air pollution
in the home, it has become clear that every home needs an
air purifier.
But with the multiple varieties available, and the big-dollar
push behind certain brands such as Sharper Image, many people
are unclear as to what the best type is for their home.
Although we will expand on this in future articles, it really
comes down to a matter of "good, better and best"
with air purifiers. As seen in the comparison chart below,
many of the popular types of air purifiers fail on some key
fronts, most notably with dust mites and medium to small particles.

The most effective air purifying technology called "photocatalysis"
a replication of how outdoor air is naturally purified:
Ions are electronically charged particles that are positive
or negative and occur naturally. There is an "ideal balance"
that nature maintains in the outdoor air. The ratio is approximately
6 positive ions to 5 negative ions. Indoors, this ratio is
thrown off balance because of the abundance of positive ions
and the lack of negative ions.
This disruption of the natural balance is primarily caused
by building materials used in the structures in which we spend
90% of our time. The negative ion gives up its charge to the
pollutants such as dust, pollen, bacteria, smoke, and formaldehyde.
This new negative particle attracts positive particles until
they become heavy enough to fall out of the air we breathe.
This process is called "agglomeration."
