Bisphenol A (BPA): Expanding Research to Impact Human Health

American Recovery and Reinvestment Act of 2009 (ARRA)

 "We know that many people are concerned about bisphenol A and we want to support the best science we can to provide the answers. Without the support of the American Recovery and Reinvestment Act, we would not have been able to expand on this research, which is of such concern to so many people." 
— Linda Birnbaum, Ph.D., director of NIEHS and the National Toxicology Program (NTP)

What is Bisphenol A?

Bisphenol A (BPA) is a controversial plastics ingredient (chemical) used primarily in the production of polycarbonate plastics and epoxy resins. It is found in items such as: plastic bottles, food storage containers, compact discs, and water supply pipes.

Why are people concerned about BPA?

  • People, including children, are exposed to BPA when it leaches from the coatings of canned foods and from plastic products, with the highest estimated daily intakes of BPA occurring in infants and children.
  •  93% of urine samples from people 6 years of age and older have detectable levels of BPA (2003-2004 National Health and Nutrition Examination Survey)
  • Evidence from animal studies indicates BPA may cause adverse effects such as obesity, behavioral changes, diabetes, early onset puberty, asthma, cardiovascular diseases, reproductive disorders, development of prostate, breast and uterine cancer, and transgenerational or epigenetic effects.
  • Researchers remain uncertain about human health problems from BPA exposure

How is the Recovery Act (ARRA) advancing BPA research?

Because BPA is a widely used chemical with potential adverse human health effects, the scientific community and NIEHS have identified BPA as a high-priority research area. Recovery Act funds will support projects addressing many of the research gaps identified by expert scientific panels, and provide a better understanding of how this chemical may impact human health.

 

Over the next two years, NIEHS will invest approximately $14 million in Recovery Act funds on BPA-related research. This research will build upon existing NIEHS funded projects and in-house research, as well as NTP projects. Collectively, the results of these new ARRA funded studies and ongoing studies should begin to chip away at uncertainties and provide a better understanding of the potential risks that exposure to bisphenol A poses to public health.
