Due to the wide use, bisphenol A (BPA) has been detected frequently in the aquatic environment. However, the information on the distribution of BPA transformation products is limited. In this study, we investigated two BPA transformation products, namely bisphenol A monomethyl ether (BPA-MME) and bisphenol A dimethyl ether (BPA-DME). This study revealed that both transformation products were widely detected in the wastewater treatment plants (WWTPs) as well as in surface water of Jiulong River and its estuary with higher detected concentrations and detection frequencies for BPA-DME. Temporal variations were observed in a WWTP based on a five-year sampling campaign. Mass load of BPA and its transformation products was evaluated and results indicated the generation of BPA-MME and BPA-DME during the wastewater treatment processes, which contributed for 1.95% BPA removal. BPA and its transformation products were also widely detected in the surface water of Jiulong River and its estuary. Results indicated their additional generation in the surface water, since BPA-MME and BPA-DME in the surface river water were with similar level or even higher than effluent in WWTPs.
由于双酚 A（BPA）的广泛使用，它经常在水生环境中被检测到。然而，关于 BPA 转化产物分布的信息有限。在这项研究中，我们调查了两种 BPA 转化产物，即双酚 A 单甲醚（BPA-MME）和双酚 A 二甲醚（BPA-DME）。本研究表明，这两种转化产物在污水处理厂（WWTP）以及九龙江及其河口的地表水均有广泛的检出，BPA-DME 的检出浓度和频率更高。基于五年的采样活动，在一个 WWTP 中观察到了时间变化。评估了 BPA 及其转化产物的质量负荷，结果表明在废水处理过程中会生成 BPA-MME 和 BPA-DME，它们对 BPA 的去除率为 1.95%。BPA 及其转化产物也在九龙江及其河口的地表水广泛检出。结果表明，它们在地表水中有额外的生成，因为地表河水中的 BPA-MME 和 BPA-DME 的水平与 WWTP 中的甚至更高。
