ClearSpatio-temporal distribution of soil microbial communities and nutrient availability around a municipal solid waste landfill
Despite its title referencing soil microbial communities near a municipal solid waste landfill, this paper studies bacterial and fungal community composition in soils surrounding a landfill — not microplastic pollution. It examines how proximity to the landfill affects microbial diversity and nutrient cycling and is not directly relevant to microplastics or human health.
Investigation of Soil-Dwelling Bacterial Community Changes Induced by Microplastic Ex posure Using Amplicon Sequencing
Researchers analyzed soil bacterial community composition after microplastic contamination, finding that different polymer types caused distinct shifts in microbial diversity and functional groups, with implications for soil nutrient cycling and agricultural productivity.
Microplastic polymer properties as deterministic factors driving terrestrial plastisphere microbiome assembly and succession in the field
Researchers incubated five common microplastic polymer types in landfill soil for 14 months and used 16S rRNA sequencing to characterize the plastisphere communities that assembled on each polymer. Polymer type was a significant deterministic factor in plastisphere microbiome composition, which differed from surrounding soil communities and varied over time.
New insights on municipal solid waste (MSW) landfill plastisphere structure and function
Characterization of a large municipal solid waste landfill plastisphere found that plastic surfaces harbored more diverse bacterial communities than surrounding refuse, with abundant plastic-degrading genera including Bacillus, Pseudomonas, and Paenibacillus detected in both environments.
Degradation of microplastics in artificially polluted soil by bacterial and fungal isolates originating from landfill leachate
Researchers tested whether bacterial and fungal isolates from landfill leachate could degrade polyethylene and polypropylene microplastics in artificially polluted agricultural soil, finding that the microbial isolates showed measurable degradation activity against both polymer types.
Earthworms Significantly Alter the Composition, Diversity, Abundance and Pathogen Load of Fungal Communities in Sewage Sludge from Different Urban Wastewater Treatment Plants

Bacterial communities on soil microplastic at Guiyu, an E-Waste dismantling zone of China
Researchers characterized bacterial communities colonizing soil microplastics at Guiyu, China — a major e-waste dismantling zone — using high-throughput sequencing, finding that microplastic-associated bacterial communities differed significantly from surrounding soil communities and varied with the type of e-waste dismantling activity.
Effects of different concentrations and types of microplastics on bacteria and fungi in alkaline soil
Researchers examined how different types and concentrations of polyethylene, polystyrene, and PVC microplastics affect soil bacteria and fungi in alkaline soil over 310 days, finding that all three stimulated enzyme activities and shifted microbial community abundance patterns.
Microbial Isolates in Microplastic-Polluted Soil
Researchers isolated and characterized microbial communities from microplastic-polluted soil, identifying bacteria capable of colonizing plastic surfaces and assessing their potential roles in plastic degradation and soil nutrient cycling.
Characterization and Human Health Risk Assessment of Fungal Species Isolated from Landfill Soil in Najaf Ashraf, Iraq
Researchers isolated fungal species from microplastic surfaces collected in environmental samples and characterized their diversity and human health risks, finding that certain opportunistic fungal pathogens were enriched on plastic surfaces compared to surrounding water and sediment.
Microplastic impacts archaeal abundance, microbial communities, and their network connectivity in a Sub-Saharan soil environment
Researchers used 16S rRNA amplicon sequencing to characterise prokaryotic communities in native plastisphere and soil from Sub-Saharan African environments with high unmanaged plastic waste. The plastisphere enriched distinct bacterial communities and archaeal taxa compared to surrounding soil, and high-population sites showed elevated potential pathogen abundance.
Distinct Bacterial and Fungal Communities Colonizing Waste Plastic Films Buried for More Than 20 Years in Four Landfill Sites in Korea
Researchers analyzed bacterial and fungal microbial communities colonizing waste plastic films buried for over 20 years at four landfill sites in Korea, finding distinct community compositions across sites and identifying microorganisms with potential for long-term plastic biodegradation.
Microbial Diversity of the Surface of Polypropylene and Low Density Polyethylene‐Based Materials (Plastisphere) From an Area Subjected to Intensive Agriculture
Researchers analyzed the microbial communities colonizing polypropylene and polyethylene plastic debris from an agricultural landfill site. They found that while overall bacterial diversity was similar between plastic surfaces and surrounding soil, the plastic-associated communities had distinct compositions with higher proportions of certain bacterial groups. The study suggests that these plastisphere communities may be actively degrading plastic additives and could harbor potential plastic-degrading organisms.
Microplastic Abundance and Characteristics in The Soil Around the Jambi Talang Gulo Landfill
Researchers measured microplastic abundance and characterized particle types in soil surrounding the Talang Gulo landfill in Jambi, Indonesia, finding that the high volume of plastic waste at the facility contributes to elevated microplastic contamination in surrounding soils through environmental weathering and fragmentation.
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.
The Analysis of the Mycobiota in Plastic Polluted Soil Reveals a Reduction in Metabolic Ability
Researchers analyzed soil fungal biodiversity and microbial metabolic profiles at three sites in northern Italy with varying levels of macro- and microplastic contamination, using Biolog EcoPlates for metabolic analysis and metabarcoding of the ITS1 ribosomal cDNA fragment for fungal community characterization. They found a significant decrease in soil microbial metabolic ability at the site with the highest microplastic concentration and distinct fungal community composition between the most pristine and more polluted sites, with Mortierellomycota dominant across all sites.

Microplastic pollution in landfill soil: Emerging threats the environmental and public health
Researchers measured microplastic contamination in soil at a landfill near residential areas in Indonesia and found extremely high levels of over 60,000 particles per kilogram. The most common types were fragments of polyethylene, PVC, polystyrene, and polypropylene. The study raises public health concerns because landfills near populated areas can release microplastics into surrounding soil and water, creating exposure pathways for nearby communities.

Degradation of microplastics and the plastisphere bacteria in the acidogenic phase of simulated municipal solid waste landfilling
Researchers simulated conditions inside a municipal solid waste landfill and found that different microplastic types (PE, PS, and PLA) aged and degraded at very different rates during the acidogenic leachate phase, with distinct microbial communities forming on each plastic type. This matters because landfills are both sources and sinks for microplastics, and understanding how plastics degrade there helps predict what eventually leaches into groundwater and surrounding soil.
