Abstract
Bisphenol A is a man-made chemical used in industry and consumer products all over the world. BPA is used in plastic beverage bottles, compact disks, canned food linings and many other products. Human exposure to this chemical comes through leaching from plastics into food and liquids. Exposure to BPA is reported to cause major complications in the endocrine systems of many animal species and human populations. Knowledge on contamination levels of BPA is essential in order to prevent future contamination and protect wildlife and humans from negative health effects. Very limited information is available on the BPA levels in various brands of bottled drinking water, fountain water, river water and lake water. In this study, BPA concentrations were measured in several brands of bottled waters and in water samples from Bee Creek, Clarks River and Kentucky Lake. For comparative purposes, water samples were also analyzed from Red Duck Creek and Mayfield Creek. Enzyme-linked immunosorbent assay method was used to determine BPA levels in these samples. Results revealed that detectable levels of BPA were found in all samples analyzed. The results were compared with published reports and evaluated the potential exposure of BPA to human populations in this region.
