Abstract

The buildup of microplastics (MPs)/nanoplastics (NPs) in aquatic biota has sparked concern due to their negative consequences on human health and the environment, making it a global issue in recent years. As a result, to achieve sustainable development goals, management of MPs/NPs contamination is crucial. Although various studies have evaluated the harmful effects of MPs/NPs, there has been insufficient attention on managing MPs/NPs by nanotechnological interventions. This review first covers the key aspects of advanced strategies, including adsorption, membrane filtration, photocatalytic degradation, magnetic separation, and electrochemistry-driven ways for efficiently sequestering/degrading MPs/NPs from the aquatic environment. An in-depth discussion on the aforementioned strategies along with various nanomaterials/nanocomposites (e.g. micromotors, microswimmers, MOFs, GO, CNTs, etc.), for the mitigation of MPs/NPs is studied. The outlook section offers insights into the conversion of MPs/NPs into valuable products by using nano interventions. Additionally, a brief overview of the economic aspects/ cost analysis of MPs/NPs management, future directions, and prospects is comprehensively documented as futuristic approach.
纳米技术干预在微/纳米塑料封存、减缓和增值产品转化中的作用综述
由于微塑料(MPs)/纳米塑料(NPs)对人类健康和环境造成的负面影响,它们在水生生物群中的积累引发了人们的关注,近年来已成为一个全球性问题。因此,要实现可持续发展目标,管理 MPs/NPs 污染至关重要。虽然已有多项研究对 MPs/NPs 的有害影响进行了评估,但人们对通过纳米技术干预来管理 MPs/NPs 的关注还不够。本综述首先介绍了先进策略的主要方面,包括吸附、膜过滤、光催化降解、磁分离和电化学驱动等有效截留/降解水生环境中 MPs/NPs 的方法。深入探讨了上述策略以及各种纳米材料/纳米复合材料(如微电机、微泳器、MOFs、GO、CNTs 等)在减缓 MPs/NPs 方面的作用。展望部分深入探讨了如何利用纳米干预措施将 MPs/NPs 转化为有价值的产品。此外,还简要概述了 MPs/NPs 管理的经济方面/成本分析、未来方向和前景。
