ClearMicroplastic-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.
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.
Characterization of microplastic-derived dissolved organic matter in freshwater: Effects of light irradiation and polymer types
Researchers examined how different types of microplastics release dissolved organic matter into freshwater under light and dark conditions. They found that polypropylene released the most organic compounds after UV exposure, while protein-like substances were the main material released by most plastics in the dark. The study indicates that microplastics may have ongoing, long-term effects on water chemistry and microbial activity in natural water bodies.
Impacts of climatic stressors on dissolved organic matter leaching from microplastics and their effects on biogeochemical processes: A review
This review examines how microplastics release dissolved organic matter as they break down in the environment, and how climate change may accelerate this process. The chemicals leached from degrading plastics can disrupt microbial communities and natural nutrient cycles, potentially increasing greenhouse gas production and altering the ecosystems that ultimately support our food and water supplies.
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.
Dissolved organic carbon leaching from microplastics and bioavailability in coastal ecosystems
Researchers evaluated dissolved organic carbon leaching from polyethylene and polypropylene microplastics in coastal ecosystems, finding that up to 85% of the leached carbon was biodegradable by microbial communities. The study found that different coastal environments, such as seagrass beds and river mouths, showed varying abilities to utilize this plastic-derived carbon, suggesting microplastics may be an underappreciated source of dissolved organic carbon in marine systems.
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.
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.
Revealing the Key Impact of Microplastic-Derived Dissolved Organic Matter Properties on Aromatic Pollutant Adsorption and the Underlying Mechanisms
Researchers examined how dissolved organic matter released from different types of microplastics affects the adsorption of aromatic pollutants like bisphenol A and naphthalene. The study found that microplastic-derived dissolved organic matter substantially suppressed the ability of treatment materials to capture these pollutants, revealing an underappreciated way that microplastic degradation products can worsen water contamination.
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 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.
Coupling 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.
Microplastic-Derived Dissolved Organic Matter Regulates Soil Carbon Respiration via Microbial Ecophysiological Controls
Researchers investigated how dissolved organic matter released by microplastics affects the way soil microbes process carbon. They found that compounds leaching from both new and aged microplastics stimulated soil carbon release, with aged microplastics having a larger effect by altering microbial community structure. The findings suggest that microplastic pollution may influence soil carbon cycling and potentially affect how effectively soils store carbon.
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.
