在城市污水排放量高、地表水流量低的城市地区，如柏林(德国)，当地下水回灌用于饮用水生产时，存在饮用水被极性有机化合物污染的潜在风险。因此，一些药用活性化合物(PHAC)在城市污水处理厂(STP)中没有被完全消除，它们作为污染物排放到接收水中。根据1996年至2000年在柏林进行的几项监测研究，在污水处理厂进水和出水样本以及污水处理厂下游的所有地表水样本中，检测到不同浓度的苯丙苯丙酸、双氯芬酸、布洛芬、丙吩酮、扑草酮和卡马西平。在补给条件下，从受污染水道附近的地下水含水层采集的样本中也发现了几种浓度高达7.3毫克/升的化合物。在柏林自来水样品中也发现了几种ng/i-水平的PHAC。(C)2002 Elsevier Science B.V.保留所有权利。
In urban areas such as Berlin (Germany) with high municipal sewage water discharges and low surface water flows there is a potential risk of drinking water contamination by polar organic compounds when groundwater recharge is used in drinking water production. Thus, some pharmaceutically active compounds (PhACs) are not eliminated completely in the municipal sewage treatment plants (STPs) and they are discharged as contaminants into the receiving waters. In terms of several monitoring studies carried out in Berlin between 1996 and 2000, PhACs such as clofibric acid, diclofenac, ibuprofen, propyphenazone, primidone and carbamazepine were detected at individual concentrations up to the mu/I-level in influent and effluent samples from STPs and in all surface water samples collected downstream from the STPs. Under recharge conditions, several compounds were also found at individual concentrations up to 7.3 mug/I in samples collected from groundwater aquifers near to contaminated water courses. A few of the PhACs were also identified at the ng/I-level in Berlin tap water samples. (C) 2002 Elsevier Science B.V. All rights reserved.
