Summary: In this study, 22 soil samples were collected from Qinghai Province, and microplastics (MPs) were detected in all samples. Various types, shapes, sizes, and colors of MPs were observed, with polyethylene terephthalate (PET) as the dominant polymer. MPs ranging from 10-50 μm accounted for 50% of all identified MPs, and pellets were the dominant shape. Colored MPs made up 64% of all MPs. This study reveals the presence of large quantities of MPs in grassland soils, including remote areas, and provides a reference for further studies on terrestrial MPs.

Summary: Soil contamination by microplastics (MPs) varies among different land use types, with urban areas having the highest abundance of MPs. The distribution and community compositions of MPs in soil are significantly different among land use types. The geographic distance, woodlands, and freshwater sediments are potential sinks for MPs in the Lihe River watershed. Soil properties such as clay content, pH, and bulk density are significantly correlated with MP abundance and fragment shape. Human activities, particularly population density and Total-Point of Interest (POI), play a vital role in exacerbating soil MP pollution. Plastic waste is a major source of MPs in urban, tea garden, dryland, and paddy field soils.

Summary: The detection of microplastics in agricultural soils in China has raised concerns due to their potential impacts on agricultural production. This review provides a summary of the abundance, sources, and impacts of microplastics in the country's agricultural soils, as well as sustainable agronomic practices to mitigate their pollution. The study found that microplastics were present in varying amounts, with the highest concentration observed in Yunnan Province. Plastic mulching films were identified as the major source of microplastics in agricultural soils, followed by abandoned greenhouses and the use of organic fertilizers containing microplastics. The presence of microplastics in soils was found to alter soil properties and affect soil biota, as well as impact crop growth and nutrient demands. Sustainable solutions proposed include the use of organic mulches, proper decommissioning of abandoned greenhouses, and setting standards for allowable microplastics contents in fertilizers and irrigation water.

Summary: Microplastics (MPs) and cadmium (Cd) have a detrimental impact on plant growth and Cd accumulation in soil-plant systems. MPs negatively affect shoot and root biomass, while promoting Cd uptake. Polyethylene has the strongest effect on Cd accumulation. MPs also lead to an increase in soil available Cd concentration and a decrease in soil pH. Moreover, MPs inhibit photosynthesis and enhance oxidative damage to plants. Overall, this study provides insights into the combined impacts of Cd and MPs on plants and offers guidelines for sustainable use of MPs in agriculture.

The study found that MPs had a high abundance in the region, with black, small size, and fragment MPs being dominant. Cultivated land had the highest average abundance, while grassland had the lowest. Human activities were the main source of MPs in cultivated land and construction land, while atmospheric deposition was more likely in woodland and grassland. The study also found that sunlight exposure and human activities could cause MPs to break down, but trees in woodland could slow down the breakage process.

Summary: The Huangshui catchment on the northeastern Qinghai-Tibet Plateau was studied to investigate the abundance, distribution characteristics, and influencing factors of microplastics (MPs) in surface agricultural soils. The results showed that MPs were present in soil with levels ranging from 6 to 444 items/kg, and smaller-sized MPs were more abundant than larger-sized MPs. The main source of MPs was residual mulching film in farmland. The spatial distribution analysis revealed higher MP abundance in agricultural soils in neighboring urban areas. Human activities, population density, and irrigation were found to play a key role in MP pollution, while the direct effects of soil properties on MP abundance remain unclear.

Summary: The contamination of microplastics and nanoplastics in the terrestrial environment is a growing concern globally, and it is believed to impact soil biota, particularly the micro and mesofauna community, through various processes that may contribute to global change in terrestrial systems. Soils act as a long-term reservoir for microplastics, accumulating these contaminants and increasing their detrimental effects on soil ecosystems. Consequently, microplastic pollution affects the entire terrestrial ecosystem, posing a potential threat to human health through their transfer in the soil food web. Ingestion of microplastics by soil micro and mesofauna can adversely affect their development and reproduction, thus impacting terrestrial ecosystems. However, the effects of microplastics on terrestrial micro and mesofauna have been largely overlooked. This review provides the most recent information on the overlooked impacts of microplastic contamination on microfauna and mesofauna communities (protists, tardigrades, soil rotifers, nematodes, collembola, and mites) in the soil.

Summary: In recent years, there has been growing concern over the prevalence and accumulation of microplastics (MPs) in the soil environment due to their resistance to degradation and long-term ecological impacts. However, there is still a lack of critical reviews on the ecological effects and effective remediation methods of MPs in soil compared to aquatic ecosystems. This review summarizes the distribution characteristics, sources, transportation, and identification techniques of MPs in soil, as well as the interactions between MPs contamination and soil ecosystems. It also discusses the effects and degradation mechanisms of different organisms on MPs degradation, highlighting the potential breakthrough of transforming enzyme stability and performance through computer protein design. This review provides guidance for further exploration of feasible approaches and advanced remediation strategies for MPs contamination in the future.

Summary: The disintegration and fragmentation of plastics into microplastics and their transport into agricultural soils can harm soil health and crop growth. This study investigated the ecotoxicity impact of polystyrene microplastics (PS-MPs) on soil quality indicators and the growth of cowpea plants. The results showed that PS-MPs negatively affected microbial biomass and enzymatic activities but increased soil respiration and microbial stress. However, cowpea plants showed neutral or positive responses to PS-MPs, with increased nutrient concentrations at low concentrations. Overall, PS-MPs have short-term ecotoxicity effects on soil quality but may not always negatively impact certain C3 plant species.
