American Chemistry MATTERS

Toxicologist Justin Teeguarden’s investigation of 150 studies on BPA, which included 30,000 people in 19 countries, including infants and children, concluded that concentrations of BPA in the blood were not high enough to result in “estrogenic” activity, as some other scientists claimed. When BPA is taken in orally, it is rapidly converted to a substance with no known biological activity as it is absorbed into the body, leaving very little BPA to enter the bloodstream. Professor Richard Sharpe of the Medical Research Council’s Centre for Reproductive Health in Edinburgh also cast doubt on studies linking BPA to obesity at the American Association for the Advancement of Science (AAAS) conference where Teeguarden presented his findings.

BPA in the blood of the general population is many times lower than blood levels that consistently cause toxicity in animals, according to a meta-analysis of almost 150 BPA exposure studies by toxicologist Justin Teeguarden of the Department of Energy's Pacific Northwest National Laboratory, Richland, Wash. According to Teegauarden, people's exposure may be many times too low for BPA to effectively mimic estrogen in the human body. His analysis was presented at an annual meeting of the American Association for the Advancement of Science.

The Wall Street Journal interviewed Justin Teeguarden on his meta-analysis of 150 studies about BPA. His analysis concluded that human exposure to an ingredient in many plastic bottles and food containers is too low to be worrisome. Teeguarden’s research was funded by the Environmental Protection Agency.

In the US, the number of chemicals routinely measured in people’s bodies has grown rapidly – our powerful analytical capabilities now allow us to identify over 1,000 individual chemicals in a single blood sample. Unfortunately, however, our analytical capabilities have outpaced our ability to interpret these data, according to Judy S. LaKind, Ph.D., President of LaKind Associates, LLC, Adjunct Associate Professor, Department of Epidemiology and Public Health, University of Maryland School of Medicine and Adjunct Associate Professor, Department of Pediatrics, Pennsylvania State University College of Medicine.
