ClearMicroplastics indirectly affect soil respiration of different-aged forest by altering microbial communities and carbon metabolism
Researchers explored how microplastics affect soil respiration in forests of different ages by altering microbial community structure and carbon metabolism. The study found microplastic levels ranging from approximately 600 to 3,858 items per sample across forest ages, and that their presence indirectly influences soil carbon cycling processes.
Stability of organic carbon pools and sequestration potential as affected under different agroforestry systems
This study evaluates how five different agroforestry systems affect soil organic carbon stability and sequestration in degraded Himalayan soils in northeast India. It is not about microplastics and is a false positive for microplastic relevance.
Microbial Responses to an Urban–Suburban–Exurban Gradient in Forest Soils: Shifts in Community Structure and Membrane Lipid Composition
Not relevant to microplastics — this study examines how soil microbial communities and membrane lipid composition shift along an urban-to-rural gradient in China, driven by urbanization and soil depth; microplastics are not a focus of the research.
Parameters of labile organic carbon as the indicators of the stability of soil organic matter under different land use
Despite its title referencing soil organic carbon and land use, this paper studies chemical indicators of soil organic matter stability under different farming practices — not microplastic pollution. It examines which carbon fractions best signal how organic matter is protected in forest and agricultural soils, and is not relevant to microplastics or human health.
Mycorrhizal-specific responses of rhizosphere soil properties and fine-root traits to polystyrene microplastic addition in a temperate mixed forest
Researchers added polystyrene microplastics to a temperate forest and found they disrupted nutrient cycling differently depending on tree type — increasing nitrogen but decreasing phosphorus near oak-type trees, and doing the opposite near maple-type trees — suggesting microplastic pollution could reshape forest ecosystems over time.
Emerging Microplastics Alter the Influences of Soil Animals on the Fungal Community Structure in Determining the Litter Decomposition of a Deciduous Tree
Researchers investigated how microplastics in forest soil affect the interactions between soil animals and fungal communities during leaf litter decomposition. They found that the presence of microplastics altered fungal community structure and disrupted the beneficial influence that soil animals normally have on decomposition processes. The study suggests that microplastic contamination in forest ecosystems could interfere with nutrient cycling by changing how decomposer communities function.
Microbial Community and Enzyme Activity of Forest Plantation, Natural Forests, and Agricultural Land in Chilean Coastal Cordillera Soils
This paper is not relevant to microplastics; it investigates how converting native forests to plantations and cropland affects soil microbial communities and enzyme activity in Chile.
Microplastic pollution alters forest soil microbiome
The impact of aged low-density polyethylene (LDPE) and polyester (PET) fibres on forest soil microbiome composition was examined. Microplastic pollution altered forest soil microbial community structure, with both polymer types affecting microbial diversity and function in ways that could influence soil health and nutrient cycling.
Microplastic effects on soil organic matter dynamics and bacterial communities under contrasting soil environments
Researchers compared microplastic effects on soil organic matter dynamics and bacterial communities across contrasting soil environments, finding that the type of microplastic polymer and soil conditions together determine whether microbial activity and carbon cycling are stimulated or suppressed.
Differential carbon accumulation of microbial necromass and plant lignin by pollution of polyethylene and polylactic acid microplastics in soil
This study found that both conventional polyethylene and biodegradable polylactic acid microplastics changed how carbon is stored in soil. The plastics increased carbon from dead microbes while decreasing carbon from plant material, with most of the additional soil carbon coming from fungal remains. These changes to soil chemistry matter because they could affect agricultural productivity and the ability of soil to store carbon, with broader implications for climate and food systems.
The Impact of Metolachlor Applications and Phytoremediation Processes on Soil Microorganisms: Insights from Functional Metagenomics Analysis
This paper is not about microplastics — it studies how phytoremediation plants affect soil microbial biodiversity in fields contaminated with the herbicide metolachlor, with no connection to microplastic pollution.
Quantifying, and assessing the impact of, microplastics in terrestrial samples
Researchers developed methodologies to quantify microplastics (1 to 1000 micrometers) in terrestrial woodland environments, addressing the significant knowledge gap about microplastic concentrations and ecological impacts in soil ecosystems compared to the more extensively studied aquatic compartments.
Forest soils accumulate microplastics through atmospheric deposition
Researchers quantified microplastics in forest soil layers and atmospheric throughfall deposition to understand how microplastics accumulate in forest ecosystems. They found that microplastics initially enriched in decomposed litter layers before accumulating in deeper mineral soil through natural litter turnover processes. The study suggests that forests act as good indicators of atmospheric microplastic pollution, with most forest soil microplastics originating from atmospheric deposition rather than other sources.
How Organic Mulching Influences the Soil Bacterial Community Structure and Function in Urban Forests
Researchers tested how different types of organic mulch affect the bacterial communities in urban forest soils. They found that wood chips and compost changed the soil's chemical properties and shifted the types of bacteria present, particularly those involved in carbon and nitrogen cycling. The study suggests that organic mulching could be a practical tool for improving the microbial health of urban soils.
Polyethylene microplastics distinctly affect soil microbial community and carbon and nitrogen cycling during plant litter decomposition
Researchers measured how polyethylene microplastics affect soil microbial communities and carbon cycling in agricultural soils, finding that microplastic addition shifted microbial diversity and suppressed key carbon mineralization processes. The results suggest microplastic accumulation in farmland could impair soil carbon storage.
The Impact of Litter from Different Belowground Organs of Phragmites australis on Microbial-Mediated Soil Organic Carbon Accumulation in a Lacustrine Wetland
Despite its title referencing wetland litter decomposition and soil carbon, this paper studies how decomposing roots and rhizomes of common reed (Phragmites australis) affect microbial communities and organic carbon accumulation in a Chinese lake wetland — not microplastic pollution. It examines how plant organ type and flooding conditions influence carbon cycling through microbial pathways and is not relevant to microplastics or human health.
Soil horizons regulate bacterial community structure and functions in Dabie Mountain of the East China
This paper is not relevant to microplastics research — it examines how soil horizon depth influences bacterial community structure and nutrient cycling functions in mountain forest soils.
The Spatiotemporal Successions of Bacterial and Fungal Plastisphere Communities and Their Effects on Microplastic Degradation in Soil Ecosystems
Researchers tracked how bacterial and fungal communities colonize microplastic surfaces in soil over time, finding that the surrounding soil type had the strongest influence on which microbes grew on the plastics. The microbial communities on microplastics were less diverse and less stable than those in the surrounding soil, but they attracted microbes with a higher capacity to break down organic carbon. The study suggests that microplastic surfaces become hotspots for carbon metabolism in soil ecosystems.
Microplastic diversity, risks and soil impacts: A multi-metric assessment across land-use systems
Researchers surveyed microplastic abundance, polymer diversity, and ecological risk across seven land-use types in India's Brahmaputra Valley, finding that built-up areas had the highest particle counts while forest soils paradoxically showed the greatest polymer hazard scores due to high-risk polymers, and that land-use type shapes both the quantity and composition of soil microplastic contamination.
Soil-Microbial CNP Content and Ecological Stoichiometry Characteristics of Typical Broad-Leaved Tree Communities in Fanjing Mountain in Spring
This paper is not about microplastics; it examines soil microbial carbon, nitrogen, and phosphorus stoichiometry across four subtropical forest types in Fanjing Mountain, China, to understand nutrient cycling and microbial nutrient limitations.
