环境隔室是随处理/未处理的废水沿着释放的可能数千种新出现的污染物（EC）的储存库。尽管对地表水中EC的检测进行了广泛的研究，但对沉积物和地下水等其他环境分区尚未进行彻底的调查。为了评估人类活动对环境的严重影响，从印度亚穆纳河流域收集了24个环境样品，包括地表水，沉积物和地下水，通过目标和可疑筛选进行了分析。地表水和沉积物样本是从位于污染严重的亚穆纳河沿着人口密集的城镇的上游和下游采集的。地下水样品采集自集水区浅层饮用水威尔斯井。液相色谱串联质谱法被用来量化10个广泛消费的药物样品。该研究还分析了定量污染物对健康的潜在危害。为了进一步评估，地表水和地下水样品进行高分辨率质谱（HRMS）筛选，对库产生的列表中的450 EC在地表水和309 EC在地下水。在样本中发现了大量的农药和药物，其中一半是首次报告。计算风险商以评估目标分析物的潜在危害。
Environmental compartments are repositories of probably thousands of emerging contaminants (ECs) released along with treated/untreated wastewater. Despite extensive studies on the detection of ECs in surface water, other environmental compartments such as sediments and groundwater are yet to be thoroughly investigated. To assess the heavy anthropogenic impact on the environment, 24 environmental samples comprising of surface water, sediment and groundwater collected from the Yamuna River basin of India were analyzed via target and suspect screening. The surface water and sediment samples were collected from upstream and downstream of densely populated cities and towns situated along the heavily contaminated river Yamuna. The groundwater samples were collected from shallow drinking water wells of the catchment. Liquid chromatography tandem mass-spectroscopy was used to quantify 10 widely consumed pharmaceuticals in the samples. The study also analyzed the potential health hazards posed by the quantified contaminants. In order to evaluate further, the surface water and groundwater samples were subjected to high resolution mass spectrometry (HRMS) screening against a library resulting in a list of 450 ECs in the surface water and 309 ECs in the groundwater. Agricultural chemicals and pharmaceuticals found abundantly in the samples and half of whom were reported first time. The risk quotient was calculated to assess the potential hazard of the target analytes.
