There are eight bisphenol analogues being identified and characterized; among them, bisphenol A (BPA) is on the priority list on the basis of its higher level of uses, occurrence, and toxicity. The endocrine system interfered by BPA has been inventoried as it has the same function as the natural hormone 17β-estradiol and binds mainly to the estrogen receptor (ER) to exhibit estrogenic activities. The BPA concentration in surface waters (14-1390 ng/L) in many parts of the world, such as Japan, Korea, China, and India, was also a significant concern. Research efforts are focusing on restricting BPA consumption as well as removing BPA in our environment especially in drinking water. Current opinion is that lignocellulosic activated carbon stimulated with BPA-degrading bacteria could have the potential to provide solution for recent challenges faced by water utilities arising from BPA contamination in water. This technology has some new trends in the low-cost biofiltration process for removing BPA. This review is to provide in-depth discussion on the fate of BPA in our ecosystem and underlines methods to enhance the efficacy of activated carbon in the presence of BPA-degrading bacteria in the biofiltration process.
目前已鉴定和描述了八种双酚类似物；其中，双酚 A（BPA）因其更高的使用量、出现频率和毒性而被优先列入清单。BPA 会干扰内分泌系统，因为它具有与天然激素 17β-雌二醇相同的功能，并主要与雌激素受体（ER）结合，表现出雌激素活性。在世界许多地方，包括日本、韩国、中国和印度，地表水中的 BPA 浓度（14-1390ng/L）也令人严重关切。研究工作的重点是限制 BPA 的消费，并消除环境中的 BPA，特别是饮用水中的 BPA。目前的观点认为，用 BPA 降解菌刺激的木质纤维素活性炭可能有潜力为水处理厂因水中 BPA 污染而面临的近期挑战提供解决方案。该技术在用于去除 BPA 的低成本生物过滤过程中有一些新的趋势。本文综述深入讨论了 BPA 在我们的生态系统中的归宿，并强调了在生物过滤过程中存在 BPA 降解菌时增强活性炭功效的方法。
