Bisphenol A remains in bodies longer than thought and/or comes from non-food sources

A study of 1,469 people taking part in a US government health survey has found that levels of bisphenol A, human exposure to which was assumed to come mainly from food sources, did not decline rapidly with increased time fasting. The researchers, from the University of Rochester Medical Center in the USA, conclude that this suggests either that bisphenol A accumulates in body tissues such as fat, or that the study participants were substantially exposed to non-food sources of bisphenol A or both.

Publishing their study in the journal Environmental Health Perspectives, they recommend "experimental pharmacokinetic studies of chronic BPA exposure, further examination of BPA levels and effects in fat, and a search for important non-food sources."
