ClearMicroplastic-derived dissolved organic matter: Generation, characterization, and environmental behaviors
This review examines how microplastics release dissolved organic matter as they break down in the environment, creating a previously overlooked source of carbon and chemical pollution. Researchers found that this microplastic-derived organic matter can interact with other pollutants, affect water quality, and influence microbial communities. The study highlights a lesser-known dimension of microplastic pollution that could have significant environmental consequences.
The Removal and Mitigation Effects of Biochar on Microplastics in Water and Soils: Application and Mechanism Analysis
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.
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.
Microplastic-derived dissolved organic matter and its biogeochemical behaviors in aquatic environments: A review
This review examines how microplastics release dissolved organic matter (MP-DOM) as they break down in water, and how these released chemicals affect water ecosystems. MP-DOM can interact with other pollutants and alter carbon cycling in natural waters, with the type and amount varying based on plastic composition and weathering conditions. Understanding what microplastics release into water as they degrade is important because these dissolved chemicals may have their own toxic effects on aquatic life and water quality.

Interplay between microplastics and natural organic matter in association with environmental processes
This review explores how microplastics interact with natural organic matter—the dissolved and particulate carbon that permeates soils and waterways—and how these interactions alter microplastic transport, surface chemistry, and biological availability. Because natural organic matter coats microplastics and changes their behavior, ignoring this interplay leads to underestimates of how far and how dangerously microplastics spread through ecosystems.

This review examines the three-way interactions between microplastics, dissolved organic matter, and coexisting pollutants, synthesizing how microplastic-DOM adsorption influences contaminant behavior and fate in the environment. The authors identify the dual roles of environmental DOM and microplastic-derived DOM in regulating pollutant adsorption, mobility, and toxicity as a critical knowledge gap.
The environmental effects of microplastics and microplastic derived dissolved organic matter in aquatic environments: A review
This review examines how microplastics interact with other pollutants in water and how aging from sunlight and weathering changes their behavior. As microplastics break down, they release dissolved organic matter and develop surface changes that increase their ability to carry harmful chemicals like pesticides and pharmaceuticals. The findings suggest that weathered microplastics in real-world environments may be more dangerous than fresh plastics used in most lab studies.

Interactions between Microplastics and Dissolved Organic Matter in the Fresh Water Environment
This review explores how microplastics interact with dissolved organic matter (DOM) — the complex mixture of carbon compounds found in rivers and lakes — and what that means for freshwater ecosystems. Microplastics readily bind to DOM, altering its distribution in sediments and affecting the microbial communities that depend on it for food and energy. DOM can also change how far microplastics travel and how available they are to aquatic organisms. The interplay between these two classes of contaminant complicates efforts to predict microplastic behavior in the environment.
How biochar works, and when it doesn't: A review of mechanisms controlling soil and plant responses to biochar
This comprehensive review synthesizes 20 years of research on biochar, a charcoal-like material made from organic waste that can improve soil health and reduce pollution. Biochar can reduce plant uptake of heavy metals by 17-39% and increase nutrient availability, making it potentially useful for cleaning up microplastic-contaminated soils. While not directly about microplastics, the findings are relevant because biochar could help mitigate the effects of soil pollutants that microplastics carry and concentrate.
