| 中文摘要 |
| 砷是一种环境中普遍存在的类金属元素，并与人类健康息息相关.砷被列为一类致癌物，地下水中砷导致的慢性中毒是全球性健康问题.环境水体中砷的形态多样和毒性不尽相同，且在采样和运输过程中易于转化，而使实验室分析结果出现误差.因此开发砷的现场分析方法和获得准确的数据是研究砷的形态转化和生物吸收过程和准确判断其毒性的基础.在过去的几十年中，砷的实验室内分析方法迅速发展并逐渐成熟，但砷的现场分析仍然存在着巨大的困难和挑战.总结归纳了近10年来（2011~2022年）环境水体中砷分析方法相关的综述，讨论了砷的比色法、发光法和电化学法等现场分析方法的研究进展，并展望未来环境水体中砷现场分析方法的发展方向，为新方法的建立与应用提供参考. |
| 英文摘要 |
| Arsenic is a ubiquitous metalloid element in the environment. Arsenic is classified as a group A carcinogen and has caused serious impacts on human health. For example, chronic poisoning caused by arsenic in groundwater is a global health problem. The forms of arsenic in environmental water are diverse, which can easily be transformed into each other during the sampling process and transportation, resulting in errors in laboratory analysis results. Therefore, developing on-site analytical methods for arsenic and acquiring accurate data are the basis for the study of the morphological transformation and bio-absorption process of arsenic and accurately evaluating its toxicity. In the past few decades, laboratory-based analytical methods for arsenic have developed rapidly, but there are still huge challenges in the on-site analysis of arsenic. This review summarized the relevant reviews on analytical methods of arsenic in environmental water in the past decade (2011-2022); discussed the advances in on-site analytical methods such as colorimetric methods, luminescence-based methods, and electrochemical methods of arsenic; anticipated the future development of on-site analytical methods for arsenic in environmental waters; and provided references for the development and applications of new methods. |
