Abstract

The emergence of polycyclic aromatic hydrocarbons (PAHs) from a variety of natural and anthropogenic sources, such as coal gasification and liquefaction plants, coke and aluminum production, catalytic cracking towers, and motor vehicle exhaust, among others, results in significant soil pollution, and a threat to human health, igniting a surge of interest in advanced research. Even though the cleanup of PAHs-contaminated areas received a great consideration. In the last decade, nanotechnology has exploded in popularity as a result of several unique properties of nanomaterials, and remediation is no exception. Thus, nano-enhanced bioremediation reported to act as a viable and effective strategy for PAHs remediation. Further, the integration of nano-enabled materials with microorganisms emerged as a promising biodegradation approach for PAHs remediation. As a result, the focus of this mini review is on depicting the possible roles of various nanomaterials in decontaminating PAHs as a green strategy by boosting the efficacy of microbial functionality, and mechanism of nanoparticles-microbes interaction in PAHs degradation. The future perspective of nano-enhanced microbial remediation of PAHs in realistic environments are also discussed.
多环芳烃污染土壤的纳米微生物修复
来自各种自然和人为来源的多环芳烃(PAHs)的出现,如煤气化和液化厂、焦炭和铝生产、催化裂化塔和机动车尾气等,造成了严重的土壤污染,并对人类健康构成威胁,引发了对先进研究的兴趣激增。尽管多环芳烃污染地区的清理工作得到了极大的重视。在过去的十年中,纳米技术由于纳米材料的一些独特的特性而迅速流行起来,修复也不例外。因此,纳米强化生物修复技术被认为是一种可行且有效的多环芳烃修复策略。此外,纳米材料与微生物的整合成为修复多环芳烃的一种有前途的生物降解方法。因此,这篇综述的重点是描述各种纳米材料作为一种绿色策略,通过提高微生物功能的功效来净化多环芳烃,以及纳米颗粒-微生物在多环芳烃降解中的相互作用机制。展望了多环芳烃纳米微生物修复技术在现实环境中的应用前景。

期刊介绍: Air, Soil & Water Research is an open access, peer reviewed international journal covering all areas of research into soil, air and water. The journal looks at each aspect individually, as well as how they interact, with each other and different components of the environment. This includes properties (including physical, chemical, biochemical and biological), analysis, microbiology, chemicals and pollution, consequences for plants and crops, soil hydrology, changes and consequences of change, social issues, and more. The journal welcomes readerships from all fields, but hopes to be particularly profitable to analytical and water chemists and geologists as well as chemical, environmental, petrochemical, water treatment, geophysics and geological engineers. The journal has a multi-disciplinary approach and includes research, results, theory, models, analysis, applications and reviews. Work in lab or field is applicable. Of particular interest are manuscripts relating to environmental concerns. Other possible topics include, but are not limited to: Properties and analysis covering all areas of research into soil, air and water individually as well as how they interact with each other and different components of the environment Soil hydrology and microbiology Changes and consequences of environmental change, chemicals and pollution.
