摘要：近年来，许多环境介质中都能检测到药品和个人护理品的存在，比如地下水、地表水和城市废水。为了评估药品和个人护理品对环境的影响，首先要对其在环境介质中的分布进行确定。这方面的研究非常有限，特别是在印度。由于阿莫西林是广泛使用的药品，所以我们选用其作为实验对象，并在新德里的污水处理厂中对其迁移转化的规律做了研究。为了获得不同季节的样品，采样要进行六个月，并且在污水处理厂的进水口和出水口同时采样，以确定阿莫西林的迁移转化规律。试验结果表明，进水浓度（未处理的污水）从“未检出”到172.6ng/L，出水浓度（处理后的污水）从“未检出”到62.5ng/L，平均去除率达到了49.7%。目前，关注的重点是对处理后污水的再利用。因此，研究结果可以为建立更好的废水再利用和相应的水资源管理方案提供参考。

Abstract: In recent years, pharmaceutical and personal care products (PPCPs) have been detected in various environmental matrices, including ground water, surface water, and municipal wastewater. In order to evaluate the impact of PPCPs on environment, their distribution must be accurately established in these matrices first, as very limited studies have been carried out especially in the Indian subcontinent. In this study, the occurrence and removal of an antibiotic, Amoxicillin, at a sewage treatment plant (STP) located in Delhi has been studied. Amoxicillin was selected for its widespread use as a prescribed over the counter drug. Sampling exercises were carried out over a period of six months so as to cover seasonal variations. Sewage samples were collected from the influents and effluents of STP to determine the occurrences and removal of the amoxicillin. Concentration of amoxicillin in the untreated raw sewage at the STP varied from “not detected” (ND) to 172.6 ng /L. After treatment, it varied from ND to 62.5 ng /L. Average removal efficiency was 49.7%. Presently, there is great focus on the reuse of the treated sewage. So, findings of the study can help to build a better understanding of reuse options for treated effluents and preparation of appropriate water resources management plans.
