A review on sources and health impacts of bisphenol A

Abstract

AbstractBisphenol-A (BPA) is a synthetic chemical used in the manufacturing of polycarbonates and epoxy resins. This paper is a review of studies reporting the occurrences and concentrations of BPA in the environment and associated impact on human health. Studies have found that at high temperature conditions such as open burning of dumped waste in developing nations can relocate BPA from plastic waste into the environment. BPA is a proven endocrine disruptor capable of mimicking or blocking the receptors and altering hormone concentrations and its metabolism. Even though it is consumed in a low dose, it can stimulate cellular responses and affect body functions. Biomonitoring studies show that human and animal exposure to BPA is rapid and continuous. In-depth studies are needed to understand the fate of these compounds particularly in the developing nations and the associated adverse health impacts of BPA due to prolonged exposure.
