"Living
Plants Purify the Air"
Indoor
air contaminants from seemingly benign sources such as furniture,
carpets, drapes, insulation, paint and office machines can cause
a variety of symptoms including respiratory irritation, dizziness,
headaches, skin irritations and rashes, nausea and vomiting. In
fact, the EPA has issued a report stating that indoor air pollution
may pose serious acute and chronic health risks with an economic
impact of tens of billions of dollars per year.
However,
a low-cost, attractive solution exists -- indoor plants!
Research
conducted by the National Aeronautics and Space Administration
(NASA) shows that you can clean the air you breathe simply by
placing live plants throughout your home and office.
NASA's
studies concluded that common indoor plants can dramatically reduce
toxic chemical levels in buildings with poor ventilation. NASA
recommends placing 15 - 18 plants in an 1800 square foot area
to clean and refresh the air.
Plants
have been found effective in reducing the levels of common toxins
such as benzene, formaldehyde and trichloroethylene (TCE).
Benzene
is a common chemical found in many products including gasoline,
inks, oils, paints, plastics and rubber. It is an additive in
detergents, explosives, pharmaceuticals and dyes and has long
been known as a skin and eye irritant.
Formaldehyde
is found in virtually all indoor environments, including foam
insulation, particle board and pressed wood products. It is used
in consumer paper produts treated with resins, including grocery
bags, waxed paper, facial tissues and paper towels. Most household
cleaning agents contain formaldehyde. The EPA recently conducted
research which shows that formaldehyde, which is an irritant to
mucous membranes of the eyes, nose and throat, may cause a rare
throat cancer in long-term occupants of mobile homes.
TCE
is used in metal degreasing and dry-cleaning proceses. It is an
ingredient in printing inks, paints, lacquers, varnishes and adhesives.
The National Cancer Society considers TCE a potent liver carcinogen.
In
the NASA study, plants which proved most effective as natural
pollution fighters included many of those commonly used in interior
plantscapes! Bromeliads, Bamboo Palm, Dracaena Marginata and
Massangeana, Janet Craig, Spathiphyllum, Spider Plant, English
Ivy, Poinsettia, Azalea, and Orchids lead the fight in effectively
reducing levels of a number of noxious gases found in almost every
home and office building.
