| Abstract: |
| Following widespread concern about microplastics pollution in marine and freshwater environments, microplastics pollution in farmland soil is now attracting more attention, and has become a hot research topic. Microplastics enter farmland soil through a variety of ways and continuously accumulate. This has an important impact on farmland soil ecosystems and may eventually pose a threat to human health through the food chain. In this study, CiteSpace software was used to analyze the literatures on microplastics pollution in soil, based on publications listed in the China National Knowledge Infrastructure database and the Web of Science core collection database, to track and compare the focus and hotpots of research in China and other countries. On this basis, this paper introduced the sources of microplastics in soil, mainly from agricultural production activities; summarized the abundance and distribution characteristics of microplastics in farmland soil; discussed the migration behavior and mechanisms of microplastics in farmland soil; and expounded the ecological effects of microplastics in farmland soil from the aspects of soil physicochemical properties, soil animals, plants, and microorganisms. Finally, this paper pointed out the problems that remain to be solved in the study of microplastics pollution in farmland soil and the prospects for future directions in this field. The construction of prevention and control technology systems were proposed to provide a scientific reference for ecological risk assessments and the control of microplastics pollution in farmland soil. |
