Feeling sick? The house or office may be to blame. Although the Consumer Product Safety Commission (CPSC) links 150 commonly used household chemicals to allergies, birth defects, cancer and psychological disorders, the U.S. Code of Federal Regulations exempts manufacturers from full labeling of products used for personal, family or household care.

The GreenNest.com was recently launched to provide education about toxins in indoor air, drinking water, personal care, pet care, baby and cleaning products, along with resources to help consumers make their homes safer.

"The EPA has deemed indoor air quality one of the top five environmental health risks the U.S. faces today," explains Ron Beres, Green Nest co- founder. "According to a Massachusetts special legislative report, 50% of all illnesses are caused by indoor air pollution. Our homes and the products and materials in them are literally making us sick."

The company's research convinced the Bereses their home and the products they used were causing the family's health problems. They learned that materials used to build and furnish homes today release the toxic chemicals they contain into the air.

Another finding was, man-made chemicals called xenoestrogens, which mimic estrogen in the human body and contribute to hormone imbalance, are found in common consumer products like plastics, detergents, birth control pills and hormone replacement therapy, and antibiotics in animal feed.

Add cleaning supplies and personal care products into the mix, and it's enough to make anyone sick.
