饮用水中的新兴污染物（ECs）由于其环境流行性和潜在毒性而对公众健康构成威胁。在我们的饮用水供应EC的发生取决于他们的物理化学性质，排放率，并通过水处理工艺去除的敏感性。长期暴露于EC的不确定的健康影响证明了其在饮用水供应中的定期监测。本文综述了表面增强拉曼光谱（Sers）技术在饮用水EC分析中的应用现状和前景。首先介绍了表面增强拉曼Sers的工作原理，并从成本、时间、灵敏度和实用性等方面对表面增强拉曼Sers与液相色谱-串联质谱进行了比较。随后，我们讨论了设计有效的Sers传感器的EC分析的基础上五个类别的每和多氟烷基物质，新型农药，药品，内分泌干扰化学品，和微塑料的策略。除了最大化Sers基底的内在增强因子之外，改善靶向EC的热点可接近性的策略也同样重要。这是一篇综述文章，重点是饮用水中的内皮细胞的Sers分析。这些讨论不仅受到推动Sers技术的众多努力的指导，而且还受到饮用水监管政策的指导。
Emerging contaminants (ECs) in drinking water pose threats to public health due to their environmental prevalence and potential toxicity. The occurrence of ECs in our drinking water supplies depends on their physicochemical properties, discharging rate, and susceptibility to removal by water treatment processes. Uncertain health effects of long-term exposure to ECs justify their regular monitoring in drinking water supplies. In this review article, we will summarize the current status and future opportunities of surface-enhanced Raman spectroscopy (SERS) for EC analysis in drinking water. Working principles of SERS are first introduced and a comparison of SERS and liquid chromatography-tandem mass spectrometry in terms of cost, time, sensitivity, and availability is made. Subsequently, we discuss the strategies for designing effective SERS sensors for EC analysis based on five categories—per- and polyfluoroalkyl substances, novel pesticides, pharmaceuticals, endocrine-disrupting chemicals, and microplastics. In addition to maximizing the intrinsic enhancement factors of SERS substrates, strategies to improve hot spot accessibilities to the targeting ECs are equally important. This is a review article focusing on SERS analysis of ECs in drinking water. The discussions are not only guided by numerous endeavors to advance SERS technology but also by the drinking water regulatory policy.
