Perchlorate (ClO) is a persistent water soluble oxyanion of growing environmental interest. Perchlorate contamination can be a health concern due to its ability to disrupt the use of iodine by the thyroid gland and the production of metabolic hormones. Its widespread presence in surface water and groundwater makes the aquatic environment a potential source of perchlorate exposure. However, the amount of published data on perchlorate origins and water contamination worldwide remains spatially limited. Here, we present an overview of research on perchlorate origins and occurrences in water, and the methodology to distinguish the different perchlorate sources based on isotope analysis. All published ranges of isotopic content in perchlorate from different sources are presented, including naturally occurring and man-made perchlorate source types, as well as the effects of isotope fractionation that accompanies biodegradation processes. An example of a case study in France is presented to emphasize the need for further research on this topic.
高氯酸盐（ClO ）是一种具有持久性、水溶性的含氧阴离子，日益受到环境领域的关注。高氯酸盐污染可能会对健康造成影响，因为它会干扰甲状腺对碘的利用以及代谢激素的生成。高氯酸盐广泛存在于地表水和地下水中，因此水环境污染可能成为高氯酸盐暴露的一个潜在来源。然而，目前全球范围内有关高氯酸盐来源和水污染的已发表数据在空间上仍然有限。在这里，我们概述了水中高氯酸盐的来源和存在情况的研究，以及基于同位素分析来区分不同高氯酸盐来源的方法。本文介绍了不同来源的高氯酸盐同位素含量的所有已发表范围，包括天然存在和人为产生的高氯酸盐源类型，以及伴随生物降解过程的同位素分馏效应。本文还提供了法国的一个案例研究示例，以强调需要进一步研究这个课题。
