The past several decades have seen increasing concern regarding the wide distribution of polycyclic aromatic hydrocarbons (PAHs) in environmental matrices. Primary toxicological data show PAHs' persistent characteristics and possible toxicity effects. Because of this pressing global issue, electroanalytical methods have been introduced. These methods are effective for PAH determination in environmental waters, even outclassing sophisticated analytical techniques such as chromatography, conventional spectrophotometry, fluorescence, and capillary electrophoresis. Herein, the literature published on PAHs is reviewed and discussed with special regard to PAH occurrence. Moreover, the recent developments in electrochemical sensors for PAH determination and the challenges and future outlooks in this field, are also presented.
过去几十年，人们对环境介质中多环芳烃（PAHs）的广泛分布越来越关注。初步毒理学数据表明，PAHs 具有持久性特征和潜在的毒性影响。鉴于这一紧迫的全球性问题，引入了电化学分析方法。这些方法可有效测定环境水中的 PAH，甚至优于色谱、常规分光光度法、荧光和毛细管电泳等复杂分析技术。本文综述了有关 PAHs 的文献，并特别讨论了 PAH 的存在情况。此外，还介绍了用于测定 PAH 的电化学传感器的最新进展，以及该领域面临的挑战和未来展望。
