在密歇根州的一个常规城市污水处理厂研究了15种药物的发生和去除效率。用高效液相色谱仪和串联质谱仪在废水和污泥相中测定了这些药物的浓度。在整个处理过程中进行了详细的质量平衡分析，以评估药物去除的贡献过程。在研究的药物中，在污水处理厂的进水中未检测到去环素、磺胺嗪、红霉素和泰乐素。在废水中检测到的其他目标药物也在相应的污泥相中发现。对氯霉素、四环素、磺胺嘧啶、对乙酰氨基酚和咖啡因的去除率为99%左右，而强力霉素、土霉素、磺胺嘧啶和林可霉素的去除率相对较低(如：
Occurrence and removal efficiencies of fifteen pharmaceuticals were investigated in a conventional municipal wastewater treatment plant in Michigan. Concentrations of these pharmaceuticals were determined in both wastewater and sludge phases by a high-performance liquid chromatograph coupled to a tandem mass spectrometer. Detailed mass balance analysis was conducted during the whole treatment process to evaluate the contributing processes for pharmaceutical removal. Among the pharmaceuticals studied, demeclocycline, sulfamerazine, erythromycin and tylosin were not detected in the wastewater treatment plant influent. Other target pharmaceuticals detected in wastewater were also found in the corresponding sludge phase. The removal efficiencies of chlortetracycline, tetracycline, sulfamerazine, acetaminophen and caffeine were >99%, while doxycycline, oxytetracycline, sulfadiazine and lincomycin exhibited relatively lower removal efficiencies (e.g.,
