The synthetic chemical bisphenol A, which is used in the linings of beer, soda and food cans, plus plastic water bottles, has been exposed as a hormone disrupter and linked to autism, cancer and other complications in the body. But it might be just the tip of the iceberg of toxic chemicals impacting us every day.
"There are 80,000 chemicals in everyday use that have never been tested," says Dr. Carlos Sonnenschein of Tufts University School of Medicine's Department of Anatomy and Cellular Biology. "It really is a nightmare."
Despite decades of research supported by the National Institute of Environmental Health Sciences on the harmful effects of BPA and other endocrine disruptors, Dr. Sonnenschein says that "very little has been done about it where it counts for the public, that is, at the regulatory end (EPA, FDA)."

Dr. Sonnenschein urges the public to get involved in banning toxic ingredients because "nothing will change," he says, "without protests before officials who run for local, state and national office. The public has an important stake in this."
The potential effects of such ingredients are widespread: "Hormonal disruptors, at their most radical, cause fetal damage during pregnancy. There's more incidence of breast cancer as there's more exposure. [Pubescent girls] are particularly sensitive to exposure. But, throughout our lives, continuous exposure means the body is storing the chemicals in fat tissue," Dr. Sonnenschein adds.
"Most people are fed up with all these chemicals. The evidence is there. It is time for the regulatory agencies to act to protect the people."
BPA: here to stay
Despite a lawsuit from the international nonprofit Natural Resources Defense Council, the FDA recently ruled to continue allowing BPA in food packaging. The NRDC's public health
program's senior scientist, Dr. Sarah Janssen, responded in a statement, which in part read:
"We believe FDA made the wrong call. The agency has failed to protect our health and safety -- in the face of scientific studies that continue to raise disturbing questions about the effects of BPA exposures, especially in fetuses, babies and young children. The FDA is out-of-step with scientific and medical research. This illustrates the need for a major overhaul of how the government protects us against dangerous chemicals."
