ClearImpact of biochar coexistence with polar/nonpolar microplastics on phenanthrene sorption in soil
Researchers found that when microplastics and biochar coexist in soil, nonpolar polyethylene weakens soil particle adhesion to biochar more than polar PBAT, affecting the sorption behavior of the pollutant phenanthrene in agricultural soils.
Combined Effects of Microplastics and Biochar on the Removal of Polycyclic Aromatic Hydrocarbons and Phthalate Esters and Its Potential Microbial Ecological Mechanism
Researchers investigated the combined effects of microplastics and biochar on the removal of polycyclic aromatic hydrocarbons and phthalate esters from contaminated soil, finding that the combination altered microbial community structure and contaminant fate differently than either amendment alone.
Combined effect of biochar and soil moisture on soil chemical properties and microbial community composition in microplastic‐contaminated agricultural soil
Biochar was applied to microplastic-contaminated agricultural soil under different moisture conditions, with results showing that biochar improved soil chemical properties and shifted microbial communities in ways that partially offset microplastic-induced degradation. The study suggests biochar as a practical soil amendment to mitigate microplastic impacts in farming systems.
Effect of different additions of low-density polyethylene and microplastics polyadipate/butylene terephthalate on soil bacterial community structure
Researchers compared the effects of biodegradable PBAT microplastics and traditional LDPE microplastics on soil bacterial communities. The study found that PBAT significantly altered soil nutrient levels and bacterial community structure in a dose-dependent manner, with low additions increasing microbial richness while higher amounts reduced it. Evidence indicates that PBAT microplastics may disrupt soil carbon-nitrogen cycling and affect key processes like nitrogen fixation and phosphorus availability.
Role of Biochar and Microbes in Remediation of Microplastics in Soil
This review examines how biochar and soil microbes can be combined to remediate microplastic-contaminated soils, synthesizing evidence for biochar's adsorption capacity and microbial degradation pathways that reduce microplastic persistence and toxicity.
Effects of biodegradable and non-biodegradable microplastics on bacterial community and PAHs natural attenuation in agricultural soils
Researchers found that biodegradable and non-biodegradable microplastics differently affect soil bacterial communities and the natural attenuation of polycyclic aromatic hydrocarbons in agricultural soils, with biodegradable plastics sometimes enhancing microbial activity while conventional plastics inhibited PAH degradation.
Influence of polyethylene terephthalate microplastic and biochar co-existence on paddy soil bacterial community structure and greenhouse gas emission
Researchers studied how polyethylene terephthalate microplastics and biochar, both common in agricultural soils, affect soil bacteria and greenhouse gas emissions during rice cultivation. They found that microplastics alone reduced bacterial diversity, but adding biochar alongside the microplastics partially restored microbial communities and altered gas emissions. The study suggests that biochar may help mitigate some of the negative soil health effects of microplastic contamination in paddy fields.
Biochar alters chemical and microbial properties of microplastic-contaminated soil
Researchers found that biochar amendments improved chemical and microbial properties of microplastic-contaminated soil, with effects varying by biochar type and water conditions, suggesting biochar as a potential remediation tool for plastic-polluted agricultural soils.
[Effect of Microplastics and Phenanthrene on Soil Chemical Properties, Enzymatic Activities, and Microbial Communities].
A 300-day experiment tested how polyethylene and polypropylene microplastics, alone and combined with the PAH pollutant phenanthrene, affected soil chemistry, enzyme activity, and microbial communities. The results showed that microplastics and phenanthrene interacted to reshape soil microbial composition and function in ways that neither contaminant produced alone, suggesting that co-contamination by microplastics and organic pollutants poses compounded risks to soil ecosystem health.
The Structural and Functional Responses of Rhizosphere Bacteria to Biodegradable Microplastics in the Presence of Biofertilizers
Researchers studied how biodegradable microplastics interact with biofertilizers in crop soils and found that even though biodegradable plastics are designed as greener alternatives, they still significantly altered soil bacterial communities and disrupted carbon metabolism pathways. The findings suggest that biodegradable microplastics may affect soil health differently than conventional plastics, but are not necessarily harmless.
Biochar's Effects and Operations on Microbial Life within the Soil Ecosystem- A Review
Not directly relevant to microplastics — this review examines how biochar additions to soil affect microbial community structure, enzymatic activity, and contaminant transformation, without a specific focus on microplastics.
Interaction effects and mechanisms of microorganisms and microplastics in soil environment
This review examines how microplastics and soil microorganisms interact: microplastics disrupt soil structure, reduce water retention, and impede plant root growth, while certain bacteria and fungi can colonize and partially degrade plastic particles through a multi-step process involving colonization, fragmentation, assimilation, and mineralization. Different polymer types (PE, PP, PS, PVC, PET) attract different microbial communities, and factors like temperature, moisture, and plastic additives affect degradation rates. Understanding these interactions is key to assessing long-term soil health impacts and developing microbial strategies to reduce plastic accumulation in agricultural soils.
Mixing effect of polylactic acid microplastic and straw residue on soil property and ecological function
A pot experiment examined effects of polylactic acid (biodegradable) microplastics and straw residue on soil microbial communities and carbon/nitrogen dynamics, finding that PLA MPs had minimal effect on bacterial diversity but interacted with carbon availability to alter microbial function. The results suggest biodegradable microplastics are not ecologically neutral in soil ecosystems.
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.

Researchers investigated how adding biochar to soil contaminated with microplastics affects bacterial communities during pepper plant growth. They found that biochar amendment helped restore bacterial diversity and shifted community composition toward beneficial species, counteracting some of the negative effects of microplastic contamination. The study suggests that biochar could be a practical soil management tool for supporting microbial health in plastic-polluted agricultural systems.
Biochar Influences Polyethylene Microplastic-Contaminated Soil Properties and Enzyme Activities

Influence of microplastics and environmentally persistent free radicals on the ability of biochar components to promote degradation of antibiotics by activated peroxymonosulfate
Researchers investigated how microplastics and environmentally persistent free radicals (EPFRs) together influence the activity of soil enzymes, finding that combined exposure produced greater inhibition of dehydrogenase and urease activity than either contaminant alone. The results indicate EPFRs can amplify the toxic effects of microplastics on soil microbial processes.

Researchers compared the bacterial communities that colonize biodegradable and conventional plastic microplastics in farmland soil. They found that biodegradable plastics (PBAT/PLA) and conventional polyethylene each attracted distinct microbial communities with different functions, including bacteria that could degrade plastics or cycle nutrients. The results suggest that even biodegradable plastics create unique microbial environments in soil that may affect soil health and function in unexpected ways.
