Many people are surprised to learn that in contemporary
life, daily chemical exposure is unavoidable. One of the most prevalent
yet overlooked sources is indoor air pollution…much of which
comes from materials that release chemicals under ambient or greater
pressure conditions, an occurrence known as offgassing. “Some
sources, such as building materials, furnishings, and household
products like air fresheners, release pollutants more or less continuously”.
Just how polluted can indoor air be?
“In the last several years, a growing body of scientific
evidence has indicated that the air within homes and other buildings
can be more seriously polluted than the outdoor air in even the
largest and most industrialized cities”. (EPA,
1995) “Indoor levels of pollutants may be 2-5 times higher
and occasionally more than 100 times higher than outdoor levels”.
