ClearSynergistic effects of nanoplastics and graphene oxides on microbe-driven litter decomposition in streams
Researchers ran a controlled aquatic experiment combining nanoplastics and graphene oxide to study their effects on leaf litter decomposition, finding that the combination altered bacterial diversity, boosted certain enzymatic activities, and produced time-dependent effects—initially inhibiting then promoting decomposition—with bacteria more affected than fungi.
Nanoplastic pollution inhibits stream leaf decomposition through modulating microbial metabolic activity and fungal community structure
Researchers found that polystyrene nanoplastics significantly inhibited leaf litter decomposition in freshwater streams, even at low concentrations. The study suggests this occurs through suppression of key microbial enzymes and shifts in fungal community structure, indicating that nanoplastic pollution could disrupt important nutrient cycling processes in freshwater ecosystems.
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.
Maize adaptation to low-dose nanoplastic–lead co-contamination: Foliar metabolic reprogramming and phyllospheric microbiome restructuring
Researchers simulated rain-deposited co-exposure of maize seedlings to nanoplastics and lead at environmentally relevant concentrations and found that while plant growth was not visibly impaired over 45 days, leaf metabolism shifted toward lipid processing and away from carbon metabolism, and the leaf microbiome restructured toward stress-tolerant microbial taxa.
Effects of nano- or microplastic exposure combined with arsenic on soil bacterial, fungal, and protistan communities
Researchers studied the combined and individual effects of arsenic and micro- or nanoplastics on soil bacterial, fungal, and protistan communities. The study found that combined pollution distinctly altered the composition of these microbial communities, with protistan communities being particularly sensitive, indicating that the co-occurrence of plastics and heavy metals in soil may have compounding ecological effects.
Nanoplastics intensify metal-induced impacts in freshwater ecosystems
Researchers found that polystyrene nanoplastics — both bare and carboxylated — intensified metal-induced impairment of leaf litter decomposition by aquatic hyphomycetes in freshwater microcosms, with combined stressor effects observed at environmentally relevant concentrations and amplified at higher exposures.
Effects of nanoplastic exposure routes on leaf decomposition in streams
Researchers conducted a microcosm experiment showing that dietary exposure to nanoplastics — through eating contaminated leaf litter — more severely disrupts stream food webs than waterborne exposure, reducing microbial enzyme activity, lowering leaf lipid content, and decreasing river snail feeding rates by up to 17%.
Dual Effect of Microplastics and Cadmium on Stream Litter Decomposition and Invertebrate Feeding Behavior
Microcosm experiments showed that combined exposure to microplastics and cadmium reduced leaf litter decomposition rates and altered fungal communities and invertebrate feeding behavior in freshwater streams more than either stressor alone.
Can microplastics from personal care products affect stream microbial decomposers in the presence of silver nanoparticles?
This study exposed freshwater fungal decomposers to microplastics from personal care products and silver nanoparticles, individually and in combination, finding that both pollutants reduced microbial activity and that combined exposure often produced additive or synergistic inhibition. The results highlight the risk to stream-based decomposition processes from personal care product-derived pollutants.
Response of a simulated aquatic fungal community to nanoplastics exposure and functional consequence on leaf decomposition
Researchers exposed a simulated stream fungal community to nano-polystyrene and found that even low concentrations (1–100 µg/L) suppressed fungal reproduction and reduced the abundance of Geotrichum candidum, slowing leaf litter decomposition by up to 27.9% and disrupting a key aquatic nutrient cycling function.
Microplastics and silver nanoparticles compromise detrital food chains in streams through effects on microbial decomposers and invertebrate detritivores
Researchers tested how microplastics and silver nanoparticles, both common pollutants from personal care products, affect stream food webs built around decomposing leaf litter. They found that both pollutants, alone and in combination, reduced fungal decomposition and harmed invertebrate feeding and growth, disrupting the base of the food chain. The study suggests that the co-occurrence of these contaminants in freshwater could impair nutrient cycling in stream ecosystems.
Effects of polypropylene micro(nano)plastics on soil bacterial and fungal community assembly in saline-alkaline wetlands
Scientists found that polypropylene nano-sized plastics disrupted soil bacterial communities more severely than micro-sized particles in saline wetland soil, reducing network complexity and altering how communities form. Bacteria were more sensitive to the plastic stress than fungi, and nanoplastics disrupted important interactions between soil microbes and plants. This suggests that as plastics break down into ever-smaller pieces in the environment, their impact on soil health may actually increase.
Can nature-based biochar and biochar nanoparticles diminish the impacts of silver nanoparticles and microplastics on microbially-driven stream detrital ecosystem?
Researchers tested whether biochar and biochar nanoparticles could offset the adverse effects of silver nanoparticles and microplastics on stream microbial decomposer communities and leaf-litter decomposition. Biochar nanoparticles actually stimulated fungal reproduction and decomposition activity and alleviated the toxicity of both silver NPs and MPs, demonstrating nature-based remediation potential.
Vertically co-distributed vanadium and microplastics drive distinct microbial community composition and assembly in soil
Researchers investigated the vertical co-distribution of vanadium and microplastics in soil profiles at a vanadium smelting site. The study found that both contaminants were present throughout the soil column and drove distinct changes in microbial community composition and assembly, suggesting combined impacts on soil ecosystem functioning.
Impacts of low concentrations of nanoplastics on leaf litter decomposition and food quality for detritivores in streams
Researchers found that low concentrations of polystyrene nanoplastics impaired leaf litter decomposition in forested streams by reducing aquatic hyphomycete fungal activity and decreasing food quality for detritivore invertebrates, threatening stream ecosystem function.
Polystyrene nanoparticles intensify the algae-mediated negative priming effect on leaf litter decomposition
Researchers showed that polystyrene nanoplastics intensify the natural inhibitory effect of benthic algae on leaf litter decomposition in streams, reducing decomposition rates by 21%, by depleting labile carbon transfer from algae to fungal decomposers and reducing fungal diversity, including key decomposer genera essential for aquatic nutrient cycling.
No short-term response of microbial or isopod-driven litter decomposition to microplastics
Researchers conducted controlled microcosm experiments testing whether microplastics at increasing concentrations affect microbially driven and isopod-driven decomposition of plant litter in soil over one month. Neither microorganism nor isopod decomposition rates were significantly altered by microplastic concentrations tested, suggesting that short-term litter breakdown may be more resilient to plastic contamination than other soil processes.
Effect of flumetsulam alone and coexistence with polyethylene microplastics on soil microbial carbon and nitrogen cycles: Elucidation of bacterial community structure, functional gene expression, and enzyme activity
Researchers tested how the herbicide flumetsulam interacts with polyethylene microplastics in soil and found that both individually and together they reduced bacteria and fungi populations. When microplastics were present alongside the herbicide, the soil bacterial community shifted more dramatically, though carbon and nitrogen cycling remained largely unchanged. The study suggests that the combined presence of herbicides and microplastics in agricultural soil creates distinct effects on microbial life compared to either contaminant alone.
Fragmentation of nanoplastics driven by plant–microbe rhizosphere interaction during abiotic stress combination
In rhizosphere experiments, plant-microbe interactions under combined cadmium and nanoplastic stress generated fragmented nanoplastics that were taken up by plant roots, demonstrating that biotic soil processes can alter nanoplastic size and enhance plant exposure.
Impact of Coexistence of Microplastics and Biochar on the Abundance and Structure of Soil Fungal Communities
Researchers investigated the effects of polypropylene, polyethylene, and PVC microplastics — alone and in combination with biochar — on soil fungal community structure, diversity, and functional prediction in agricultural soil. Microplastics increased overall fungal abundance but reduced diversity indices, with dominant taxa including Ascomycota, Basidiomycota, Mortierella, Aspergillus, and Fusarium, and coexistence with biochar amplifying these effects beyond microplastics alone.
Polystyrene nanoplastics reshape the peatland plants (Sphagnum) bacteriome under simulated wet-deposition pathway: Insights into unequal impact of ecological niches
Researchers simulated wet deposition of polystyrene nanoplastics onto Sphagnum moss in peatlands and assessed effects on epiphytic and endophytic bacterial communities over 30 days. Nanoplastics reduced bacterial diversity on plant surfaces and disrupted co-occurrence network stability, with epiphytes showing greater sensitivity than endophytes, demonstrating that atmospheric nanoplastic deposition can reshape peatland microbiomes.
Bacterial community are more susceptible to nanoplastics than algae community in aquatic ecosystems dominated by submerged macrophytes
Researchers conducted a mesocosm experiment to test how nanoplastics affect bacterial and algal communities in aquatic ecosystems with submerged plants. They found that bacterial communities were significantly more sensitive to nanoplastic exposure than algal communities, with notable shifts in bacterial composition and function. The study reveals that different groups of microorganisms in natural water environments respond very differently to nanoplastic contamination.
Plant community responses to polypropylene microplastic and cadmium co-exposure: Implications for mycorrhizal strategies in a coastal wetland
Researchers conducted a mesocosm experiment to assess how polypropylene microplastics and cadmium interact in their effects on coastal wetland plant communities. They found that the combination of microplastics and heavy metals altered soil properties, plant community composition, and root traits in species-specific ways. The study suggests that mycorrhizal strategies play a role in how different plant species respond to this combined contamination.
Aging microplastic aggravates the pollution of heavy metals in rhizosphere biofilms
Researchers found that aging microplastics aggravate heavy metal pollution in rhizosphere biofilms, with weathered MPs accumulating more metals and altering microbial community structure in the root zone, potentially increasing contaminant transfer to plants.
