ClearCoupling between Increased Amounts of Microplastics and Dissolved Organic Compounds in Water
This review synthesizes current knowledge on how microplastics in freshwater interact with dissolved organic compounds (DOC), acting as both absorbers and releasers of organic chemicals through hydrophobic interactions, van der Waals forces, and pi-pi stacking. The authors identify a critical gap: while much is known about how MPs adsorb specific pollutants, almost nothing is known about how growing MP concentrations alter the natural dissolved organic matter cycle in lakes and rivers — a potentially major but overlooked ecological impact.
Interactions of microplastics, dissolved organic matter, and coexisting pollutants: Mechanisms, environmental implications, and knowledge gaps
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.
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.
Microplastic-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.

Review of decisive factors for controlling generation and environmental effect of dissolved organic matter from (micro)plastics.
This review examines the composition, formation mechanisms, and environmental risks of dissolved organic matter (DOM) derived from plastics, identifying key controlling factors such as UV irradiation, temperature, and microbial activity, and assessing DOM's potential ecological impacts including toxicity and facilitation of contaminant transport.
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.
Characterization of the Differences in Dissolved Organic Matter (DOM) Adsorbed on Five Kinds of Microplastics Using Multiple Methods
Researchers developed an optimized method for extracting dissolved organic matter directly from microplastics collected across five different environmental settings. They found that the type of microplastic, its shape, and the environment it was collected from all significantly influenced how much organic matter was adsorbed, with porous extruded polyethylene showing the highest enrichment. The study provides new analytical approaches for characterizing how microplastics interact with organic matter in aquatic and sediment environments.
Molecular-level insights into derivation dynamics of microplastic-derived dissolved organic matter
Researchers used molecular-level analysis to investigate the formation dynamics of dissolved organic matter derived from microplastics (MPs-DOM) in natural surface waters, finding that this ubiquitous contaminant affects not only aquatic organisms but also undergoes complex chemical transformations that influence its environmental fate and toxicological relevance.
Environmental behavior and mechanistic interactions of biochar-derived dissolved organic matter with microplastics
This review examines how dissolved organic matter released from aging biochar interacts with microplastics in soil and water environments. Researchers found that biochar-derived organic matter can alter the surface properties, mobility, and toxicity of microplastic particles through mechanisms like adsorption and coating. The study highlights these interactions as an important but underappreciated factor in understanding the environmental fate of microplastics.
Effects of Microplastics and Organic Fertilizer Regulation on Soil Dissolved Organic Matter Evolution
This study examined how microplastic addition to soil affects dissolved organic matter (DOM) evolution, focusing on the interactions between microplastics as carbon sources and organic fertilizer. Microplastics altered DOM composition and quantity, with effects on soil carbon cycling that varied by plastic type and organic fertilizer combination, suggesting complex interactions between plastic pollution and soil amendment practices.
Adsorption of microplastic-derived organic matter onto minerals
Dissolved organic matter (DOM) released from weathered microplastics was studied for its adsorption onto soil minerals, a process relevant to microplastic fate and potential contaminant transport.

Adsorption of dissolved organic matter (DOM) on polystyrene microplastics in aquatic environments: Kinetic, isotherm and site energy distribution analysis
Polystyrene microplastics adsorbed both humic and fulvic acids from water via hydrophobic and pi-pi interactions, with humic acid showing stronger binding due to higher molecular energy sites. The results indicate that dissolved organic matter in natural waters will coat microplastic surfaces and alter their environmental behavior.

Dissolved organic matter leached from microplastic (MPs-DOM) divergently alters pyrene adsorption in soil
Dissolved organic matter leached from microplastics (MPs-DOM) was shown to alter microbial community structure and chemical cycling in water. This suggests that even without direct particle ingestion, the chemical leachates from plastics can reshape aquatic ecosystems.
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.

This perspective examines how algae-derived dissolved organic matter (DOM) in eutrophic waters dynamically influences the aggregation behavior of nanoplastics, as DOM can adsorb onto nanoplastic surfaces and alter their colloidal stability. The authors discuss how DOM molecular composition and hydrophilicity change with phytoplankton bloom progression, affecting nanoplastic fate and transport in eutrophic aquatic systems.
Research progress on environmental occurrence of microplastics and their interaction mechanism with organic pollutants
This review summarizes how microplastics in the environment interact with organic pollutants—adsorbing, carrying, and releasing them. Microplastics act as mobile carriers for persistent organic chemicals, altering their distribution and toxicity in ecosystems and the organisms, including humans, that consume them.
Process analysis of microplastic aging during the photochemical oxidation process and its effect on the adsorption behavior of dissolved organic matter
Accelerated UV/persulfate and UV/chlorine oxidation experiments showed that both processes aged microplastics in distinct ways — altering surface chemistry and morphology — which in turn changed how the MPs adsorb dissolved organic matter (DOM) from water. Because aged MPs in real environments bind organic contaminants differently than pristine plastics, these findings are essential for predicting the long-range transport and ecological risk of weathered microplastics in natural water systems.
