摘要：

目的：探讨BPA（2,2-双(4-羟基苯基)丙烷，Bisphenol A）浓度和温度对胶质瘤细胞系摄取和析出10B的影响方法：将C6和U251两种胶质瘤细胞系，及大鼠正常脑胶质细胞培养在含不同浓度BPA（10B浓度分别为20、40、60、80、100 μg/mL）的培养基中24 h后，采用感应耦合等离子体原子发射光谱（ICP-AES）法测定细胞内硼的含量；将C6细胞培养在含不同浓度BPA的培养基中培养24 h后，更换为不含10B培养基，在不同温度条件（4、25、37 ℃）下继续培养，并分别于换液后的结果：细胞内硼浓度随培养基中BPA浓度的增加而增高，胶质瘤细胞内10B浓度约为正常胶质细胞的2.2倍；温度越高，细胞内硼析出速度越快。结论：BPA对胶质瘤细胞系具有一定亲和力；细胞对10B的析出速率具有温度依赖性。

Degradation of endocrine disruptor bisphenol A in drinking water by ozone oxidation

XU Bin, GAO Naiyun, RUI Min, WANG Hong, WU Haihui

《环境科学与工程前沿（英文）》 2007年 第1卷 第3期   页码 350-356 doi: 10.1007/s11783-007-0060-y

摘要： The ozone oxidation of endocrine disruptor bisphenol A in drinking water was investigated. A stainless completely mixed reactor was employed to carry out the degradation experiments by means of a batch model. With an initial concentration of 11.0 mg/L, the removal efficiencies of BPA (bisphenol A) could be measured up to 70%, 82%, and 90% when the dosages of ozone were 1, 1.5, and 2 mg/L, respectively. The impacts on BPA degradation under the conditions of different ozone dosages, water background values, BPA initial concentrations, and ozone adding time were analyzed. The results showed that ozone dosage plays a dominant role during the process of BPA degradation, while the impact of the contact time could be ignored. UV wavelength scanning was used to confirm that the by-products were produced, which could be absorbed at UV254. The value of UV254 was observed to have changed during the ozonation process. Based on the change of UV254, it could be concluded that BPA is not completely degraded at low ozone dosage, while shorter adding time of total ozone dosage, high ozone dosage, and improvement of dissolved ozone concentration greatly contribute to the extent of BPA degradation. The effects of applied HO dose in ozone oxidation of BPA were also examined in this study. The O-HO processes proved to have similar effects on the degradation of BPA by ozone oxidation.

《环境科学与工程前沿（英文）》 2015年 第9卷 第3期   页码 475-481 doi: 10.1007/s11783-014-0640-6

摘要： Endocrine disrupting compounds (EDCs), pharmaceuticals and personal care products (PPCPs) have attracted much attention due to widespread contamination in aquatic environment. In this study, we determined 13 EDCs and PPCPs in fish blood, bile and muscle by using gas chromatography-mass spectrometry (GC-MS). The limits of quantitation (LOQ) were in the ranges of 0.23–2.54, 0.22–2.36 ng·mL , and 0.24–2.57 ng·g dry weight (dw) for fish blood, bile and muscle, respectively. Recoveries of target compounds spiked into sample matrices and passed through the entire analytical procedure ranged from 65% to 95%, from 60% to 92% and from 62% to 91% for blood, bile and muscle, respectively. The methods were applied to the analysis of fish from a lake in California. Target compounds were relatively low in bile, and only bisphenol A (BPA) and diclofenac were measurable near the LOQ. Seven of 13 compounds were detected in blood, with total concentrations up to 39 ng·mL . Only BPA was frequently found in muscle, with mean concentration of 7.26 ng·g dw. The estimated daily intake of BPA through fish consumption for U.S. resident was significantly lower than the tolerable daily intake recommended by the European Food Safety Authority. This study showed that the exposure to the bisphenol A from fish diet is unlikely to pose a health risk.

Occurrence of bisphenol A in surface and drinking waters and its physicochemical removal technologies

摘要： Bisphenol A (BPA), an endocrine disrupting compound, has caused wide public concerns due to its wide occurrence in environment and harmful effects. BPA has been detected in many surface waters and drinking water with the maximum concentrations up to tens of μg·L . The physicochemical technology options in eliminating BPA can be divided into four categories: oxidation, advanced oxidation, adsorption and membrane filtration. Each removal option has its own limitation and merits in removing BPA. Oxidation and advanced oxidation generally can remove BPA efficiently while they also have some drawbacks, such as high cost, the generation of a variety of transformation products that are even more toxic than the parent compound and difficult to be mineralized. Only few advanced oxidation methods have been reported to be able to mineralize BPA completely. Therefore, it is important not only to identify the major initial transformation products but also to assess their estrogenic activity relative to the parent compounds when oxidation methods are employed to remove BPA. Without formation of harmful by-products, physical separation methods such as activated carbon adsorption and membrane processes are able to remove BPA in water effluents and thus have potential as BPA removal technologies. However, the necessary regeneration of activated carbon and the low BPA removal efficiency when the membrane became saturated may limit the application of activated carbon adsorption and membrane processes for BPA removal. Hybrid processes, e.g. combining adsorption and biologic process or combining membrane and oxidation process, which can achieve simultaneous physical separation and degradation of BPA, will be highly preferred in future.
