Carpeting
In an effort to modernize and quiet down classroom noise many schools now use rugs. However, there is more to carpeting than meets the eye. Volatile organic compounds (VOCs) emitted by carpet backings and adhesives have been blamed for health problems ranging from nausea to skin irritation.
Synthetic glues and fibers release toxic chemical fumes contributing to indoor air problems. Studies involving carpet installation workers have determined higher levels of leukemia, central nervous system damage, lung, oral, and testicular cancers.
Even small amounts of fumes can cause serious health problems. One study of mice exposed to carpet fumes developed abnormalities of their respiratory, neuromuscular and neurological systems. Many died, and autopsies found kidney damage and lesions in the liver and brain. It didnt matter if the carpeting was brand new, or twelve years old!5
To further illustrate the serious health risks associated with carpeting, insurance companies are reluctant to grant life insurance to rug installers, who must first sign a release against future cancers developed down the road.
There are several things to be aware of concerning carpeting: 1) the glues, latex backings, and rubber padding are all toxic and off-gas, 2) pesticides used to control carpet beetles may include arsenic and benzene, 3) carpets become reservoirs for tracked in pesticides, heavy metals, and other toxins.6
AND...
Children and babies spend a great deal more time in close contact with carpeted interiors than do lab mice. This maybe another environmental assault on the health of children growing up in industrialized nations where petrochemicals dominate.
