摘要
采用固相萃取和液相色谱双质谱联用技术，调查研究了某市水源水、净水厂和小区管网（龙头）等水样中的65种药品和个人护理用品（PPCPs）分布和浓度情况。结果表明，在水源水、净水厂原水和小区管网（龙头）水中分别检出11、12和5种PPCPs，其平均浓度分别在0～11．20ng／L、0～12．35ng／L、0～1．31ng／L范围内；检出频率较高的污染物主要有4种抗生素类药（磺胺甲恶唑、氧苄氨嘧啶、泰妙菌素、林肯霉素）、2种消炎解热镇痛药（氨糖美辛、安替比林）、1种抗精神病药（舒必利）、1种血液循环系统药物（卡巴克络）、1种抗心律失常药（达舒平）、1种B阻滞剂（阿替洛尔）；常规处理工艺并不能对所有目标物质有很好的去除效果，卡巴克络、磺胺甲恶唑等物质仍能在常规工艺出水中检出，而深度处理工艺的臭氧单元能对所检测的物质起到很好的去除作用，在深度处理工艺出水中检测不到任何目标污染物。
The levels of 65 kinds of PPCPs （Pharmaceuticals and personal care products）were investigated in water sources, water treatment plants, pipe water and tap water in a city by the method of solid phase extraction and LC/MS/MS analysis. The results showed that 11,12,5 kinds of PPCPs were detected in samples of water sources, water treatment plants, pipe/tap water respectively. And the average concentration of PPCPs were in the range of 0-11. 20 ng/L, 0-12. 35 ng/L, 04 1.31 ng/L. There were 4 antibiotics （sulfamethoxazole, trimethoprim, tiamulin, lincomycin）, 2 antiphlogistic （indomethacin and antipyrine）, 1 antipsyehotic （sulpride）, 1 hemostatic （carbazochrom）, 1 anti-arrhythmic drugs （disopramidle）, 1 β-blocker （atenolol） that were detected frequently. Some PPCPs detected could be removed by conventional treatment process, while some PPCPs, such as sulfamethoxazole and carbazochrom, were hard to be removed and can be detected in the effluents. However, oznoation process can remove PPCPs efficiently. No target PPCPs could be detected in the effluents of advanced treatment process.
