对韩国表层沃茨中31种内分泌干扰物（EDCs）和药品及个人护理产品（PPCPs）的存在情况进行了调查。选择该地区是因为首尔地区缺乏关于微污染物对河流的疑似污染的信息，尽管该地区超过99%的饮用水来自地表沃茨，该地区约有1500万居民。从首尔汉江上游/下游和沿着以污水为主的小溪中采集样品，采用液相色谱-串联质谱（LC-MS/MS）-电喷雾电离（ESI）和大气压化学电离（APCI）进行分析。大多数目标化合物中检测到的汉江样品（63%）和污水为主的小溪样品（79%）。碘普罗胺、阿替洛尔、TCPP、TECP、麝香酮、萘普生、避蚊胺、卡马西平、咖啡因和二苯甲酮在河流和小溪样品中经常被检测到，尽管以流出物为主的小溪样品中的平均浓度（102 ng/L-3745 ng/L）显著高于河流样品中的平均浓度（56 ng/L-1013 ng/L）。而17β-雌二醇、17α-炔雌醇、孕酮和睾酮在河流和小溪中均未检出（<1 ng/L）。许多目标化合物（15）被发现是正相关（超过0.8）的常规水质参数（化学需氧量，生化需氧量，溶解有机碳，紫外吸光度）。这项研究的结果提供了越来越多的证据表明，某些内分泌干扰物和PPCPs通常发生在汉江的污水排放的结果。
The occurrence of 31 selected endocrine disrupting compounds (EDCs) and pharmaceuticals and personal care products (PPCPs) in Korean surface waters was investigated. The area was selected since there is a lack of information in the Seoul area on the suspected contamination of rivers by micropollutants, although over 99% of drinking water is produced from surface waters in this area that has a population of approximately 15million inhabitants. Samples were collected from upstream/downstream and effluent-dominated creeks along the Han River, Seoul (South Korea) and analyzed by liquid chromatography with tandem mass spectrometry (LC-MS/MS) with electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI). Most target compounds were detected in both the Han River samples (63%) and the effluent-dominated creek samples (79%). Iopromide, atenolol, TCPP, TECP, musk ketone, naproxen, DEET, carbamazepine, caffeine, and benzophenone were frequently detected in both river and creek samples, although the mean concentrations in effluent-dominated creek samples (102ng/L–3745ng/L) were significantly higher than those in river samples (56ng/L–1013ng/L). However, the steroid hormones 17β-estradiol, 17α-ethynylestradiol, progesterone, and testosterone, were not detected (<1ng/L) in both the river and creek samples. Numerous target compounds (15) were found to be positively correlated (over 0.8) to the conventional water quality parameters (chemical oxygen demand, biochemical oxygen demand, dissolved organic carbon, and ultraviolet absorbance). Results of this study provide increasing evidence that certain EDCs and PPCPs commonly occur in the Han River as the result of wastewater outfalls.
