我们调查了香港污水处理厂和受纳沃茨中7类16种抗生素（β-内酰胺类、氟喹诺酮类、大环内酯类、磺胺类、四环素类、甲氧苄啶类和氨酚类）的存在和归宿。头孢氨苄、阿莫西林、氧氟沙星和红霉素-H2O在整个维多利亚港的海水中普遍存在，表明持续排放到环境中。这是少数几项报告头孢氨苄和阿莫西林在污水和海水中频繁出现的研究之一（污水中分别为170-5070和64-1670纳克/升;海水中分别为6.1-493和0.64-76纳克/升）。七个污水处理厂每天向海港排放的污水量估计为14.4公斤。台风避难所似乎也发挥了重要作用，作为抗生素的来源，其边界内的浓度升高就是证明。质量平衡估计表明，大量抗生素未经处理厂就排入港口。(C)2009爱思唯尔有限公司保留所有权利。
We investigated the presence and fate of 16 antibiotics belonging to seven groups (beta-lactams, fluoroquinolones, macrolides, sulfonamides, tetracyclines, trimethoprim and amphenicols) in effluents of sewage plants and receiving waters in Hong Kong. Cefalexin, amoxicillin, ofloxacin and erythromycin-H2O were ubiquitous in sea water throughout Victoria Harbour, indicating continuous discharge to the environment. This is one of the few studies reporting the frequent occurrence of cefalexin and amoxicillin in sewage effluents and sea water (170-5070 and 64-1670 ng/L in sewage; 6.1-493 and 0.64-76 ng/L in sea water, respectively). Mass flows from seven sewage plants discharged an estimated total of 14.4 kg/day to the Harbour. Typhoon shelters also appeared to play an important role as sources of antibiotics, as evidenced by elevated concentrations within their boundaries. Mass balance estimations suggested significant quantities of antibiotics are discharged to the Harbour without passage through treatment plants. (C) 2009 Elsevier Ltd. All rights reserved.
