ClearMicroplastics trapped in soil aggregates of different land-use types: A case study of Loess Plateau terraces, China
Researchers measured microplastic abundance in soil aggregates from four land-use types on China's Loess Plateau, finding MPs trapped in aggregates across all land uses with farmland soils having the highest concentrations. Woodland soils had the lowest MP content and the most stable aggregate structure, suggesting land use substantially controls both MP accumulation and aggregate integrity.
Cropping systems reshape the distribution and risks of microplastics in soil aggregates in a karst agricultural region
Researchers investigated how different cropping systems influence the distribution and ecological risks of microplastics within soil aggregates in a karst agricultural region. The study found that cropping system type reshaped microplastic abundance, morphology, and polymer composition across macro-, meso-, and micro-aggregate fractions, with implications for understanding microplastic persistence in fragile karst soils.

This paper is not relevant to microplastics research — it characterises particle size distribution and depth to bedrock in Chinese agricultural soils to inform soil classification and land management.
[Abundances and Morphology Patterns of Microplastics Under Different Land Use Types on the Loess Plateau].
Researchers investigated the abundance and morphological patterns of microplastics across different land use types on the Loess Plateau in China, examining how agriculture, grassland, and other land uses shape microplastic accumulation in soils of this major agricultural production region.

Researchers mapped microplastic pollution and influencing factors across different ecologically fragile karst zones in Guizhou Province, China, finding that land use, soil properties, and ecosystem fragility all affect microplastic distribution in these sensitive landscapes.
Microplastics influence organic carbon depletion in macroaggregates and soil structural stability in the Yanhe catchment
Researchers investigated how microplastics within soil aggregate fractions affect organic carbon retention and structural stability in the Yanhe catchment, finding that microplastics accelerate organic carbon depletion from macroaggregates and reduce soil structural stability. The results suggest that microplastic contamination in agricultural soils may compound land-use-driven degradation of soil quality.
Seasonal dynamics and typology of microplastic pollution in Huixian karst wetland groundwater: Implications for ecosystem health
Researchers tracked microplastic levels in groundwater beneath a karst wetland in China across seasons, finding contamination ranging from about 1 to 49 particles per liter. The unique cave-and-underground-river geology of karst regions allows microplastics to migrate from the surface into groundwater more easily than in other terrains, with agricultural runoff and domestic wastewater identified as the main pollution sources.
Microplastics Disrupt Soil Aggregate Stability and Associated Nutrient Dynamics in Mulched Salt-Affected Agricultural Soils
Researchers investigated how microplastic accumulation affects soil aggregate stability and nutrient dynamics in salt-affected agricultural soils in northeastern China. They found that high microplastic abundance significantly disrupted soil structure, reducing large aggregates and creating nutrient imbalances, with the elevated salinity and low organic matter of these soils amplifying the damage. The study highlights the need for targeted strategies to mitigate microplastic contamination in salt-affected farmland where plastic mulch is heavily used.
The distribution of microplastics in soil aggregate fractions in southwestern China
Researchers investigated microplastic distribution across different soil types in agricultural and forested areas near a lake in southwestern China and found plastic particles in every sample, with concentrations as high as 42,960 particles per kilogram. Approximately 95% of the particles fell within the microplastic size range, and fibers were the dominant form, likely originating from textiles and agricultural materials. The study demonstrates that microplastic contamination in soils is extensive and varies with land use practices.
Peer Review #1 of "An investigation into the response of the soil ecological environment to tourist disturbance in Baligou (v0.1)"

Microplastics occurrence and distribution characteristics in mulched agricultural soils of Guizhou province
Researchers surveyed agricultural soils in the karst landscape of Guizhou province, China, to assess microplastic contamination from plastic mulch farming. They found microplastics were widespread, with fibers and fragments being the most common types, and that contamination levels varied with mulching history and soil characteristics. The study underscores how plastic mulch used in agriculture is a significant source of soil pollution in regions with unique geological features.

Researchers measured microplastic levels across different land use types on China's Loess Plateau and found an average abundance of nearly 3,000 particles per kilogram of soil. Construction land and cultivated areas had the highest concentrations, while grassland and woodland had lower levels. The study demonstrates that human land use patterns directly influence how much microplastic accumulates in soil across this important agricultural region.

Determinants of environmental changes in human-modified ecosystems: Effects of plastics on moisture gradients, nutrients, and clay properties
Researchers examined how plastic pollution affects soil properties in human-modified ecosystems through field experiments in China and Rwanda, combined with laboratory tests on clay mixed with PET microplastics.
