In an article published on the science news provider Scientific Blogging Science 2.0 Steve Hentges, director of the industry association BPA coalition questions whether bisphenol A (BPA) exposure is sufficiently high to cause harm. He argues that urine biomonitoring can provide a reasonable measure of BPA exposure in a population. In his article, Hentges drafts biomonitoring data from the U.S. National Health and Nutrition Examination Survey (NHANES) and the Canadian study sponsored by the Health Canada (the Canadian Ministry of Health) and compares it to the Tolerable Daily Intake (TDI) for BPA as set by Health Canada. He cites Health Canada stating that the “dietary exposure to BPA through food packaging is not expected to pose a health risk to the general population, including newborns and young children”. Hentges points out that the observable downward trend can only be considered suggestive and that the data does not provide any information on the sources of BPA and potential replacements, though this may be of particular interest.
