ABSTRACT

Microplastics are described as plastic debris and are generally less than 5 mm in size. The growing concentration of microplastics in water bodies is causing severe concern among researchers. The identification and removal of microplastics from wastewaters are the main issues. Hence, this review focuses on the identification and removal of microplastics. The toxicity produced by the microplastics and their effects is also discussed. This review sheds light on the change of properties of plastics upon degradation. The characterization of microplastics is also essential. The microplastic adsorption ability results in carrying various other contaminants to different habitats. So, the source, fate, and transportation of microplastic debris are also discussed. The removal of microplastics is conducted by efficient methodologies such as adsorption, filtration, and chemical methods. They are all discussed, along with their applications, mechanism, advantages, and limitations.

摘要

微塑料被描述为塑料碎片，尺寸通常小于 5 毫米。水体中微塑料浓度的不断增加引起了研究人员的严重关注。废水中微塑料的识别和去除是主要问题。因此，本综述的重点是微塑料的识别和去除。还讨论了微塑料产生的毒性及其影响。这篇综述揭示了塑料降解后性能的变化。微塑料的表征也至关重要。微塑料的吸附能力导致将各种其他污染物带到不同的栖息地。因此，还讨论了微塑料碎片的来源、归宿和运输。微塑料的去除是通过有效的方法进行的，例如吸附、过滤法、化学法。对它们以及它们的应用、机制、优点和局限性进行了讨论。
