Human BPA levels may have been underestimated

Exposure to common industrial chemical and endocrine disruptor bisphenol A (BPA) has been linked to a range of health impacts, from reproductive disorders to heart disease. Although widespread, the level of exposure of most people to BPA was thought to be low enough that the potential for harm was minimal, but new research has indicated that the method of measuring exposure used thus far may be seriously flawed.

As they relate in their report in The Lancet Diabetes and Endocrinology, when researchers compared the indirect method of measuring BPA exposure with a newer, direct method, they found that the indirect method consistently returned an inaccurately low reading. The direct measurement found levels of BPS as much as “44-times higher than the latest geometric mean for adults in the USA reported by the National Health and Nutrition Examination Survey (NHANES),” note the authors.
