Occurrence and Ecological Impacts of Microplastics in Soil Systems: A Review
AI summary Read the abstract
This review provides a comprehensive overview of microplastic occurrence and ecological impacts in soil systems, an area that has received less scientific attention than aquatic environments. Researchers summarized how microplastics enter soils through agricultural films, biosolids, and irrigation, and how they affect soil organisms, nutrient cycling, and plant health. The study predicts a rapid increase in soil microplastic research and calls for standardized methods to assess the risks.
Microplastics, as a group of emerging contaminants, are receiving growing attention. During the last decade, their occurrence and toxicity in aquatic ecosystems have been intensively studied and reviewed, but less attention has been paid on soil ecosystems. Given the importance of soil ecosystems and the call for increasing research on soil from scientific communities, it is predicted that relevant studies will boom in the following years. The present review intends to provide a comprehensive overview of current knowledge on microplastic pollution in soil environments. We critically summarize the source, contamination level and fate of microplastics in (industrial and arable) soils. Then, we thoroughly describe what effects have been observed on soil microbes, animals and plants, and analyze what insights we can get from available information. Finally, we identify knowledge gaps that need to be filled and give suggestions for future research.

Microplastics in soils: A review of methods, occurrence, fate, transport, ecological and environmental risks
AI summary Read the abstract
This review examines the sources, detection methods, and environmental behavior of microplastics in soils, an area that has received far less attention than marine microplastic pollution. Researchers found that microplastics interact with soil properties and organisms in complex ways, potentially entering the human food chain. The study calls for standardized methods and more research into how these tiny plastic particles move through and affect terrestrial ecosystems.

Microplastic Pollution in the Soil Environment: Characteristics, Influencing Factors, and Risks
AI summary Read the abstract
This review systematically examined the characteristics, influencing factors, and environmental risks of microplastic pollution in soil environments. The study notes that compared to aquatic systems, research on soil microplastics is relatively lacking, and highlights that agricultural practices, waste disposal, and atmospheric deposition are major pathways for microplastic entry into soils.
