Soil and groundwater contamination has been raised as a concern due to the capability of posing a risk to human health and ecology, especially in facing highly toxic and emerging pollutants. Because of the prevalent usage of perfluorooctanoic acid (PFOA), in industrial and production processes, and subsequently the extent of sites contaminated with these pollutants, cleaning up PFOA polluted sites is paramount. This research provides a review of remediation approaches that have been used, and nine remediation techniques were reviewed under physical, chemical, and biological approaches categorization. As the pollutant specifications, environmental implications, and adverse ecological effects of remediation procedures should be considered in the analysis and evaluation of remediation approaches, unlike previous research that considered a couple of PFAS pollutants and generally dealt with technical issues, in this study, the benefits, drawbacks, and possible environmental and ecological adverse effects of PFOA-contaminated site remediation also were discussed. In the end, in addition to providing sufficient and applicable understanding by comprehensively considering all aspects and field-scale challenges and obstacles, knowledge gaps have been found and discussed.
由于土壤和地下水污染有可能对人类健康和生态系统构成威胁，特别是在面对高毒性和新兴污染物时，因此人们对此表示担忧。由于全氟辛酸（PFOA）在工业和生产过程中的广泛使用，以及受这些污染物污染的地点的数量之多，清理受 PFOA 污染的地点至关重要。本研究回顾了已使用的修复方法，并根据物理、化学和生物方法分类，审查了九种修复技术。由于在分析和评估修复方法时，应考虑污染物特性、环境影响和修复程序的生态负面影响，与之前仅考虑几种 PFAS 污染物且通常涉及技术问题的研究不同，在本研究中，还讨论了受 PFOA 污染场地修复的益处、缺点以及可能对环境和生态产生的不利影响。最后，除了通过全面考虑各个方面和现场规模的挑战和障碍提供充分和适用的理解外，还发现并讨论了知识空白。
