| 中文摘要: |
| 近年来我国的土壤污染问题日益严重,严重危害着人类的生活环境与身体健康,而其中主要的有机污染物之一为多环芳烃(PAHs)。PAHs作为一种持久性有机污染物在全球范围内广泛存在,其主要污染来源于人为因素。由于PAHs复杂的杂环芳环结构、较强的疏水性和较高的热稳定性等,使其在土壤中不易自然降解因而具有较高的持久性。本文综述PAHs的主要污染来源、暴露途径及其对人体的危害,并从物理、化学和生物三个方面简要介绍土壤中PAHs的修复方法,并分析每种方法的优势以及面临的挑战,同时新兴的修复技术结合三种修复技术的优点,具有更好的修复效果和应用前景,但仍存在着一些亟待研究的问题。本文以期为土壤中PAHs的修复提供借鉴,并为今后的研究方向提供新的思路。 |

| In recent years, the soil pollution problem in China is becoming more and more serious, it is seriously endangering human living environment and health, and one of the main organic pollutants is polycyclic aromatic hydrocarbons (PAHs). PAHs, as a kind of persistent organic pollutants, are widely present in the world and mainly come from human factors. Because of their complex heterocyclic aromatic ring structure, strong hydrophobicity, and high thermal stability of PAHs, it is highly persistent in the soil. This work reviews the sources of PAHs, exposure pathways, their harmful effects on humans, and mainly introduces the remediation methods for PAHs in soil from three aspects: physical, chemical, and biological. The advantages and challenges of each method are also analyzed, meanwhile the emerging remediation technologies combined the advantages of three remediation methods possessed better remediation effects and higher application prospects. However, there are still some problems that need to be further studied. This work aims to provide the reference for the remediation of PAHs in soil and new ideas for future research directions. |
