Global plastic pollution has been a serious problem since many years and micro (nano) plastics (MNPs) have gained attention from researchers around the world. This is because MNPs able to exhibit toxicology and interact with potentially toxic elements (PTEs) in the environment, causing soil toxicity. The influences of MNPs on the soil systems and plant crops have been overlooked despite that MNPs can accumulate in the plant root system and generate detrimental impacts to the terrestrial environments. The consumption of these MNPs-contaminated plants or fruits by humans and animals will eventually lead to health deterioration. The identification and measurement of MNPs in various soil samples is challenging, making the understanding of the fate, environmental and ecological of MNPs in terrestrial ecosystem is limited. Prior to sample assessment, it is necessary to isolate the plastic particles from the environment samples, concentrate the plastic particles for analysis purpose to meet detection limit for analytical instrument. The isolation and pre-concentrated steps are challenging and may cause sample loss. Herein, this article reviews MNPs, including their fate in the environment and toxic effects exhibited towards soil microorganisms, plants and humans along with the interaction of MNPs with PTEs. In addition, various analysis methods of MNPs and management of MNPs as well as the crucial challenges and future research studies in combating MNPs in soil system are also discussed.
多年来，全球塑料污染一直是一个严重问题，微（纳）塑料（MNPs）已引起世界各地研究人员的关注。这是因为MNPs能够表现出毒理学特性，并与环境中的潜在有毒元素（PTEs）相互作用，导致土壤毒性。尽管MNPs会在植物根系中积累并对陆地环境产生有害影响，但它们对土壤系统和农作物的影响却一直被忽视。人类和动物食用这些受MNPs污染的植物或果实最终将导致健康恶化。在各种土壤样品中识别和测量MNPs具有挑战性，这使得我们对MNPs在陆地生态系统中的归宿、环境和生态的了解有限。在进行样品评估之前，有必要从环境样品中分离出塑料颗粒，浓缩塑料颗粒以便进行分析，以满足分析仪器的检测限。分离和预浓缩步骤具有挑战性，可能会导致样品损失。在此，本文对MNPs进行了综述，包括它们在环境中的归宿、对土壤微生物、植物和人类表现出的毒性效应以及MNPs与PTEs的相互作用。此外，还讨论了MNPs的各种分析方法、MNPs的管理以及在应对土壤系统中的MNPs方面的关键挑战和未来研究。
