土壤中有毒多环芳烃（PAHs）的修复一直是一个重要的话题，因为暴露于具有致癌、诱变和致畸潜力的污染土壤会导致严重的健康影响。在多环芳烃污染土壤的修复中，纳米材料由于其纳米尺度所具有的特殊特性，近年来受到了广泛的关注。然而，这些NMs的有用性和效力取决于它们对特定场地条件和土壤性质的适应。由于目前还没有对纳米材料的应用进行全面的综述，因此分析、讨论和解读纳米材料在修复含多环芳烃污染土壤中的最新进展具有重要意义。本综述主要介绍了纳米零价铁（nZVI）、金属氧化物、碳基NMs和聚合物基材料的最新进展。强调了有助于提高工艺的NMs的每个特征。此外，定性地总结了获得最佳结果的操作条件。本文还特别关注了土壤和污染物的类型，这是影响工艺性能的主要影响因素。此外，从污染物迁移行为、植物毒性和土壤微生物群落组成的变化等方面综述了NMs和PAHs对土壤性质的潜在影响。展望了纳米锰在污染土壤中的应用前景。
The remediation of toxic polycyclic aromatic hydrocarbons (PAHs) in the soil is always an important topic since exposure to contaminated soil with carcinogenic, mutagenic, and teratogenic potential can result in serious health effects. With respect to the remediation of PAHs contaminated soil, nanomaterials (NMs) have recently received a great deal of attention due to the special characteristics arising from their nanoscale sizes. However, the usefulness and potency of these NMs depend on their adaption to specific site conditions and soil properties. Since there is no comprehensive review of the applications of NMs, it is of great importance to analyze, discuss, and interpret the latest progress in the application of NMs for the remediation of contaminated soils containing PAHs. This overview essentially captures the novel advances made in nano zero valent-iron (nZVI), metal oxides, carbon-based NMs, and polymer-based materials. Each characteristic of NMs that contributes to the enhancement of the process is highlighted. Moreover, operational conditions in which the best-obtained results are achieved qualitatively summarize. This review is also given special attention to the type of soil and pollutant, which are major influential factors to affect the performance of the process. Furthermore, the potential implication of NMs and PAHs on soil properties is reviewed in terms of the changes in migration behavior of pollutants, plant phytotoxicity, and soil microbial community composition. Discussion on future perspectives is presented on the use and prospects for the application of NMs in contaminated soils.
