Pharmaceuticals and hormones (PhACs) enter the aquatic environment in multiple ways, posing potential adverse effects on non-target organisms. They have been widely detected in drinking water sources, challenging water companies to reassure good quality drinking water. The aim of this study was to evaluate the concentration of sixteen PhACs in both raw and treated drinking water sources in the Metropolitan Area of Turin-where Società Metropolitana Acque Torino (SMAT) is the company in charge of the water cycle management-and evaluate the potential human health risks associated to these compounds. Multivariate spatial statistical analysis techniques were used in order to characterize the areas at higher risk of pollution, taking into account the already existing SMAT sampling points' network. Health risks were assessed considering average detected concentrations and provisional guideline values for individual compounds as well as their combined mixture. As reported in the just-issued Drinking Water Directive 2020/2184/UE, in order to establish priority substances, a risk assessment of contaminants present in raw drinking water sources is required for monitoring, identifying potential health risks and, if necessary, managing their removal. The results showed negligibly low human health risks in both raw water sources and treated water.
药品和激素（PhACs）通过多种途径进入水生环境，对非目标生物构成潜在的不利影响。它们在饮用水源中被广泛检测到，这给自来水公司带来了挑战，使其需要确保提供优质饮用水。本研究的目的是评估都灵大都市区原水和处理后饮用水源中16种药品和激素的浓度（在该地区，都灵市自来水公司（SMAT）负责水循环管理），并评估与这些化合物相关的潜在人类健康风险。考虑到SMAT现有的采样点网络，采用多元空间统计分析技术来确定污染风险较高的区域。根据检测到的各化合物平均浓度、临时指导值及其混合情况评估健康风险。正如刚刚发布的《饮用水指令2020/2184/UE》所报告的，为了确定优先物质，需要对原饮用水源中存在的污染物进行风险评估，以进行监测、识别潜在健康风险，并在必要时管理其去除。结果表明，原水和处理后水中对人类健康的风险极低。
