Per- and polyfluoroalkyl substances (PFAS) are a class of persistent organic pollutants that have attracted much attention in recent years, which has the characteristics of diverse species, refractory degradation, long-distance transportation, easy bioaccumulation, etc. The distribution, accumulation, and potential toxicity of PFAS in water and organisms have received extensive attention worldwide. However, studies on PFAS distribution and transportation in soil are still hovering at a preliminary stage. The PFAS pollution surveys in Chinese soils are mainly concentrated in the economically developed eastern regions. The types and concentrations of PFAS in soils are directly related to the industrial types, atmospheric deposition, and human activities in these surveyed areas, which are similar to foreign soil surveys. Traditional perfluoro carboxylic acid (PFCAs) and perfluoro octane sulfonate (PFSAs) are the most important types of PFAS in Chinese soils. This study reviewed the distribution characteristics, transportation pathways, and influencing factors of PFAS in Chinese soils, as well as domestic and foreign control policies on PFAS pollution. Meanwhile, this study further pointed out the shortcomings of the current research on the distribution and control of PFAS in soil in order to provide a reference for the investigation, research, and control of PFAS pollution in Chinese soils.
全氟和多氟烷基物质（PFAS）是一类近年来备受关注的持久性有机污染物，具有种类多样、难降解、远距离传输、易生物累积等特点。PFAS在水体和生物体中的分布、累积及潜在毒性已受到全球广泛关注。然而，关于PFAS在土壤中的分布和迁移的研究仍处于初步阶段。中国土壤中PFAS污染调查主要集中在经济发达的东部地区。土壤中PFAS的种类和浓度与这些调查地区的工业类型、大气沉降及人类活动直接相关，这与国外土壤调查情况类似。传统的全氟羧酸（PFCA）和全氟辛烷磺酸（PFSA）是中国土壤中最重要的PFAS类型。本研究综述了PFAS在中国土壤中的分布特征、迁移途径、影响因素以及国内外对PFAS污染的管控政策。同时，本研究进一步指出了当前土壤中PFAS分布与管控研究的不足，以便为中国土壤PFAS污染的调查、研究和管控提供参考。
