Bisphenol A and its Analogues: Human Exposure and Biological Effects-A Review

Review: A Review on Bisphenol A and its Anlogues

Abstract

 The most prevalent exposure of bisphenol A (BPA) to biological systems has directed health organizations to reduce its safe dosage and the stringent regulation by developed countries that led to ban of BPA-based (Bisphenol analogues) baby bottles. This in turn has opened a new window for ongoing entry of bisphenol analogues into consumer market. Recently, there has been tremendous growth in both production and application of bisphenol analogues to achieve the "BPA-free" claim. Nevertheless, due to growing epidemiological evidence concerning the toxicological effects of these bisphenol analogues in both in vivo and in vitro systems, the debate regarding the safety concerns over bisphenols is back. Structural analogues of bisphenol A had been identified in food products, human and environment matrices. Present review is an attempt to recapitulate the presence of bisphenols in food and environment matrices as well as their concerning physiological effects in animal models and human groups. But, due to structural analogy of these substitutes, their endpoints on biological functions are comparable to original compound or in certain situations, more harmful than original compound. Unfortunately, other potentially harmful alternatives are emerging and it is therefore advised that the replacement of bisphenol A with other structural analogues must be executed with great care.
