Abstract

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.

摘要

在过去的几十年里，人们越来越关注多环芳烃 (PAH) 在环境基质中的广泛分布。主要毒理学数据显示了 PAH 的持久特性和可能的​​毒性影响。由于这个紧迫的全球性问题，引入了电分析方法。这些方法对环境水中的 PAH 测定非常有效，甚至优于复杂的分析技术，如色谱法、常规分光光度法、荧光法和毛细管电泳法。在此，对发表的关于 PAH 的文献进行了回顾和讨论，特别是关于 PAH 的发生。此外，还介绍了用于测定 PAH 的电化学传感器的最新发展以及该领域的挑战和未来展望。
