Bisphenol A (BPA), which is a monomer that can be used in the manufacturing of polycarbonate plastics and certain can liners, and is also found in certain consumer products and food containers (Chapin et al., 2008). It is currently accepted that BPA is safe as the way it is used, and that the major intake of BPA is from the diet and there are assessments confirming this with showing no other sources of exposure being shown. There has been a reduction is urinary BPA following an alteration in ones diet when turning to fresh foods, also confirming the assessment mentioned. These findings have been challenged because there is speculation about the unmentioned measured serum BPA concentrations found in humans, additionally failure to mention different ways of exposure rather than food ingestion. “The preponderance of data, findings from international regulatory agency reviews, and assessments integrating exposure, biomonitoring and human pharmacokinetic data support the conclusion that serum BPA concentrations in humans >1 ng/ml are not realistically achievable in populations exposed orally via food.”
There has been consistent…
