ClearThe Ultraviolet Irradiation Aging Characteristics of Microplastics in Soil under the Action of Biochar
Researchers characterized how microplastics change physically and chemically under ultraviolet irradiation aging, documenting surface cracking, yellowing, and shifts in chemical functional groups. These aging signatures are important for understanding the environmental fate and increased toxicity of weathered microplastics.

The study suggests biochar as a practical soil amendment to mitigate microplastic impacts in farming systems.

Researchers reviewed the use of biochar as a tool for remediating microplastic-contaminated soil. The study found that biochar application shows promise for addressing soil microplastic pollution by altering soil properties in ways that can reduce microplastic mobility and mitigate their negative effects on soil structure, plant growth, and biogeochemical cycling.
Pyrolysis temperature matters: Biochar-derived dissolved organic matter modulates aging behavior and biotoxicity of microplastics
Researchers found that dissolved organic matter from biochar (a charcoal-like soil additive) affects how microplastics age in the environment by generating reactive oxygen species that alter the plastic surfaces. Importantly, microplastics aged in the presence of biochar-derived compounds caused significantly more inflammation and tissue damage in living organisms than freshly made microplastics. This means microplastics in the real world, where they interact with soil compounds, may be more toxic than laboratory tests with clean plastic particles suggest.

Researchers investigated how dissolved organic matter from biochar affects the photoaging of polystyrene microplastics under different conditions. The study found that biochar produced at lower pyrolysis temperatures significantly accelerated microplastic degradation, suggesting that biochar-derived organic matter may play an important role in the environmental weathering and breakdown of plastic particles.
Enhanced degradation of polylactic acid microplastics in acidic soils: Does the application of biochar matter?
Researchers studied how adding biochar to acidic soil affects the breakdown of polylactic acid microplastics over one year. They found that both chicken manure and wood waste biochars accelerated the degradation of the biodegradable microplastics by altering soil chemistry and microbial activity. The findings suggest that biochar could be a useful tool for speeding up the decomposition of biodegradable plastic residues in agricultural soils.

Researchers conducted a 24-week paddy soil weathering experiment with polyethylene microplastics in the presence or absence of pyrochar or hydrochar, finding that weathering roughened and discolored PE particle surfaces, and that weathered PE microplastics showed altered sorption capacity toward cadmium, bisphenol A, and dimethyl phthalate compared to original particles.
Effect of biochar on microplastics penetration treatment within soil porous medium under the wetting-drying cycles and optimisation of soil-biochar mixing format
Researchers tested whether plant-based biochar mixed into soil could prevent microplastics from moving deeper into the ground during repeated wetting and drying cycles that mimic seasonal rainfall. They found that biochar significantly improved microplastic retention in the soil, and experimented with different soil-biochar mixing configurations to optimize performance. The study suggests that biochar amendments could be a practical strategy for reducing microplastic migration through agricultural soils.

Polyethylene microplastics hamper aged biochar’s potential in mitigating greenhouse gas emissions
Polyethylene microplastics (1–5% by weight) significantly reduced the greenhouse gas-mitigating benefits of aged biochar in agricultural soil, decreasing soil aggregation and altering dissolved organic matter dynamics—raising concerns about microplastic interference with biochar-based carbon sequestration strategies.
Photodegradation modifies microplastic effects on soil properties and plant performance
Researchers examined how UV-driven photodegradation alters the effects of microplastics on soil properties and plant growth.

Soil aggregation alterations under soil microplastic and biochar addition and aging process
An eight-month experiment found that polyethylene and polypropylene microplastics disrupted soil structure by breaking apart soil clumps, and this damage worsened as the plastics aged over time. Surprisingly, adding biochar, which is often proposed as a soil improvement, actually made some of the microplastic damage worse for certain soil aggregate sizes. This research shows that microplastic contamination in agricultural soil can degrade soil health in ways that may be difficult to reverse.

The results improve predictions of where microplastics migrate and accumulate in soils and aquifers.
Effects of photoaging on structure and characteristics of biofilms on microplastic in soil: Biomass and microbial community
Scientists studied how sunlight aging changes the way bacteria colonize microplastics in soil, finding that weathered plastics attracted different bacterial communities than fresh plastics.

This review examines how biochar can be used to both remove microplastics from water and mitigate their harmful effects in soils. Researchers found that woody biochar was the most effective type for adsorbing microplastics, while also helping to restore soil enzyme activities and microbial communities disrupted by plastic contamination. The study calls for further research into optimizing biochar applications and understanding the long-term environmental implications of biochar-microplastic interactions.
