Research of New Pollutant Microplastics in Soil
Summary
This review summarizes microplastic pollution in agricultural soils, covering sources, abundance, transport pathways, and interactions with heavy metals and organic pollutants. The authors highlight that soil microplastic contamination is a growing threat to food security and soil ecosystem health.
Abstract Microplastic pollution is one of the key new pollutants to be controlled in ecological environment protection. This article describes in detail the abundance and distribution of microplastics in the soil, their sources and access routes. It focuses on the analysis of the accumulation, migration, and degradation of microplastics in the soil, as well as the interaction with metal and organic pollutants and their environmental effects; expounds the impact of microplastics on soil organisms and soil quality and ecological risks and discuss the exposure pathways and potential human health risks of microplastics in the soil are discussed. Finally, the future direction and focus of the research on microplastics in the soil environment are prospected. It is expected to provide information and scientific guidance for a comprehensive understanding of the present and future of soil environmental microplastics research.

Sources, pollution, and ecological impacts of soil microplastics-A review
A comprehensive review summarized the sources, distribution, and ecological impacts of microplastics in soil environments, synthesizing evidence on how plastics affect soil organisms, structure, and agricultural productivity. The review calls for urgent policy action to address soil microplastic contamination as a threat to food security.
Microplastics as an Emerging Environmental Pollutant in Agricultural Soils: Effects on Ecosystems and Human Health
This review examines how microplastics enter and move through agricultural soil ecosystems, affecting soil properties, nutrient cycling, and the organisms that live in and depend on healthy soil. Researchers found that microplastics can alter key biogeochemical processes and interact with co-existing pollutants like heavy metals and pesticides, potentially compounding their harmful effects. The study highlights the need for prevention and control strategies as microplastic contamination of farmland becomes an increasingly recognized environmental and potential human health concern.
Interactions of microplastics and main pollutants and environmental behavior in soils
This review examined how microplastics interact with major soil pollutants including heavy metals, pesticides, and organic contaminants, analyzing their combined environmental behavior, transport mechanisms, and ecological hazards in agricultural and terrestrial soils.
Microplastics inAgricultural Soils: Sources, Fate,and Interactions with Other Contaminants
This review examines microplastics as emerging soil contaminants, focusing on their interactions with co-occurring pollutants such as heavy metals, pesticides, and antibiotics, and assessing the compound toxic risks these combinations pose to agricultural ecosystems and food safety.
Microplastic Pollution in Terrestrial Ecosystems and Its Interaction with Other Soil Pollutants: A Potential Threat to Soil Ecosystem Sustainability
This review examines microplastic pollution in soils and how plastic particles interact with other pollutants like pesticides and heavy metals. About 80% of all plastic waste produced in the last 75 years has ended up in landfills or the environment, where it breaks into microplastics that alter soil health and contaminate crops. The combined effects of microplastics with other soil pollutants could threaten food safety and ultimately human health.
