Within the past 15 years, compound-specific stable isotope analysis has continued to increase in popularity in the area of contaminant hydrology of organic molecules. In particular, in cases where concentration data alone are insufficient to elucidate environmental processes unequivocally, the isotope signature can provide additional unique information. Specifically, it can help answer questions about contaminant source apportionment, quantification of biotic and abiotic processes, and identification of transformation reactions on a mechanistic level. We review advances in laboratory and field investigations and exemplary applications in contaminant hydrology via stable isotope analysis. We also highlight future directions in the field.
在过去的 15 年中，化合物特异性稳定同位素分析在有机分子污染物水文学领域的应用越来越受欢迎。特别是在仅依靠浓度数据无法明确阐明环境过程的情况下，同位素特征可以提供额外的独特信息。具体来说，它可以帮助回答有关污染物来源分配、生物和非生物过程量化以及在机制水平上识别转化反应的问题。我们通过稳定同位素分析回顾了实验室和现场调查的进展以及在污染物水文学中应用的实例。我们还强调了该领域的未来发展方向。
