This review of over 60 studies examines the sources, global distribution, and analytical methods for microplastics in soil, finding that agricultural soils are particularly contaminated via sewage sludge application, plastic mulch, and atmospheric deposition. The authors call for standardized extraction and identification protocols to enable cross-study comparisons.

Abstract Microplastics are emerging persistent pollutants that have been extensively detected in aqueous environments. Yet, scientists have little knowledge of microplastic pollution in soils. This study reviewed over 60 articles, with the following objectives: (i) to discuss sources and the global distribution of microplastics in soils; (ii) to evaluate current extraction techniques and analytical methods for microplastics in soils; and (iii) to comprehensively assess their adverse impacts on soils and soil organisms. Moreover, this review highlights the lack of research into microplastic contamination in soils as a significant knowledge gap. Research into the fate, sources and analytical techniques of soil microplastics and the interactions between soil organisms, soils and microplastics is essential in order to underpin management decisions aimed at safeguarding the ecological integrity of our soils. © 2020 Society of Chemical Industry

Analysis and Effects of Microplastics in the Agricultural Soils

AI summary Read the abstract

This review summarizes current knowledge about microplastic contamination in agricultural soils, including how it gets there (mulch films, sewage sludge, irrigation) and what effects it has on soil health. The authors highlight the lack of standardized methods for sampling and testing soil, which limits understanding of the true extent of the problem.

Microplastics as pollutants in agricultural soils

AI summary Read the abstract

This review examines how microplastics end up in agricultural soils through sewage sludge application, wastewater irrigation, plastic mulch films, and atmospheric deposition. Researchers found that microplastics interact with soil organisms and can alter soil structure and microbial communities, but standardized detection methods are still lacking. The study highlights the need for research on how microplastics move through soil, their effects on crop health, and global policies to address this growing agricultural concern.

Existence and fate of microplastics in terrestrial environment: A global fretfulness and abatement strategies

AI summary Read the abstract

This review covers the global spread of microplastics in soils, farmland, and other land environments, finding contamination from sources like sewage sludge, plastic mulch, and irrigation water. The study highlights that terrestrial microplastic pollution may actually be greater than marine pollution and poses risks to soil organisms, crop growth, and human health through the food chain.
