A Study on Environmental Bisphenol A Pollution in Plastics Industry Areas

Abstract

Bisphenol A (BPA), a well-known endocrine-disrupting chemical, is receiving increasing concerns regarding its adverse effects on the endocrine system in wildlife and humans. This study was designed to investigate BPA pollution in environmental media in plastics industry areas and to explore the relationship between BPA pollution and the characteristic of different plastics industry. A total of 66 river water samples, 6 aquatic animal samples, and 64 surface soil samples were collected from three cities with different characteristics of plastics industry in southeast China. BPA concentrations in river water (240–5680 ng L−1), aquatic animals (116.13–477.42 ng g−1), and surface soil (38.70–2960.86 ng g−1) were highest in Yuyao City where the plastics industry mainly involved in the production of plastic raw materials. BPA concentrations in Taizhou City were modest and comparable to those reported elsewhere though Taizhou is characterized by its massive production of plastic products. BPA concentrations in Wenzhou City were the lowest where relatively low activities are involved in the plastics industry. Our data indicate that the plastics industry involved the use of BPA as an intermediate in production of raw plastics such as polycarbonate plastics and epoxy resins was the dominant cause of BPA pollution in the surrounding environments.
