Because we spend 80% to
90% of our time indoors,
and most of that at home, our home is where we are most
likely to be exposed to toxic chemicals. (1) This is especially true
for young children, who spend even more time indoors than adults and
older children.
Why
are
our homes so toxic?
In the last two decades - the same period during which childhood
illness has increased - there has been an alarming increase of toxic
chemicals in household products, and for the first time we have been
sealing our homes for energy efficiency. Weather stripping and caulking
do an excellent job of keeping the air you have heated or cooled inside
your home. But the lack of openings for air to escape also traps
chemical air pollutants, resulting
in a greater concentration of pollutants indoors than out.
EPA studies found that even in urban areas with high concentration of
toxic chemicals was higher indoors than outdoors - in some cases ten,
twenty, thirty, and even up to seventy times higher indoors!(2)
In 1987, the EPA undertook an ambitious program to identify and compare
the urgency of environmental problems. The idea was that, with limited
resources, the agency should be focusing on those pollutants that pose
the greatest risk to society. Among the top hazards were those found
indoors, including exposure to cleaning
products.(3)
Another study, conducted over fifteen-year
period,
found that women who worked at home had a 54% higher death rate from
cancer than women who had jobs away from home. The study concluded that
the increased death rate was due to daily exposure to the hazardous
chemicals found in ordinary household products. (4) Obviously, the
children in those homes were exposed to the same chemicals, with even
greater risk for illness.
How Do Toxic
Chemicals Get Into Your Body?
Ingestion
- eating or drinking a substance - is the
route of
most immediate poisonings that lead to accidental death. Young children
are especially vulnerable to household poisonings through ingestion.
With their natural curiosity, they learn by putting things in their
mouths.
Inhalation - breathing a
substance
- is more common, and can be much more harmful than ingestion.
Toxic fumes can be released even when a chemical is tightly sealed in
it's container.
Absorption - admitting a
substance
through the skin - is an often unsuspected route of exposure. It is now
known that any chemical which touches the skin can be absorbed and
spread throughout the body. The skin is so absorbent that nicotine
patches and analgesic creams administer medications into the
bloodstream through the skin.
