Effects and fate of metal-based engineered nanomaterials in soil ecosystem: A review

引用

Pedosphere 2024年第5期34卷 843-852页

作者： Qibin WANG Peng ZHANG Weichen ZHAO Shakoor noman Adeel MUHAMMAD Guikai ZHU Yi SUN Quanlong WANG Yaqi JIANG Yukui RUI Beijing Key Laboratory of Farmland Soil Pollution Prevention and Remediation College of Resources and Environmental Sciences China Agricultural University Department of Environmental Science and Engineering University of Science and Technology of China School of Geography Earth and Environmental Sciences University of Birmingham BNU-HKUST Laboratory of Green Innovation Advanced Institute of Natural Sciences Beijing Normal University at Zhuhai China Agricultural University Professor Workstation of Yuhuangmiao Town China Agricultural University Professor Workstation of Sunji Town

Metal-based engineered nanomaterials (MENMs) are increasingly being used in people’s working lives. Although MENMs have important effects on soil ecosystem and play an important role in solving soil environmental problems, the hazards associated with MENMs cannot be ignored. Therefore, more and more scholars have studied the behavior and effects of nanomaterials in soils in recent years. In this review, we explore the articles on MENMs and soil ecosystem retrieved from various databases from 2013 to 2022. We discuss the mechanisms of MENM toxicity, the current state of soil ecosystem, the ecological effects of MENMs on soil microbes, earthworms, and plants, and the ways by which soil organisms take up MENMs. We now know that although MENMs have positive effects on soil ecosystem, their potential hazards are not negligible. Therefore, it is necessary to investigate the effects of MENMs on soil organisms. Meanwhile, we should pay more attention to the negative effects of MENMs on soil ecosystem while exploring their positive effects on soil ecosystem in future research.
