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 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.
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.
Transport of persistent organic pollutants: Another effect of microplastic pollution?
This review examines how microplastics act as vectors for persistent organic pollutants (POPs) in aquatic environments, covering the physical and chemical factors governing pollutant adsorption and desorption. The authors discuss how interactions between microplastics and POPs vary with polymer type, particle properties, and environmental conditions, and when these interactions may result in toxic effects on aquatic organisms.
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.
Interactions of microplastics with organic, inorganic and bio-pollutants and the ecotoxicological effects on terrestrial and aquatic organisms
This review systematically examines how microplastics interact with organic pollutants, heavy metals, and biological contaminants in the environment. Researchers found that microplastics can adsorb and transport these pollutants, creating complex combinations that may be more toxic to organisms than either pollutant alone. The study highlights the risks these interactions pose to both ecosystem health and human well-being.
Interactions between microplastics and organic compounds in aquatic environments: A mini review
Researchers reviewed the mechanisms of interaction between microplastics and organic compounds in aquatic environments, examining factors related to the plastics themselves, the organic compounds, and environmental conditions. The study found that properties like crystallinity, surface area, and weathering state of microplastics all influence how they adsorb and transport organic pollutants, with implications for environmental and health risk assessments.
Adsorption of organic pollutants by microplastics: Overview of a dissonant literature
This review critically examines the scientific literature on how microplastics adsorb organic pollutants in aquatic environments. Researchers found significant inconsistencies across studies regarding the mechanisms and extent of pollutant uptake by microplastics, noting that factors like particle size, polymer type, and environmental conditions all play important roles. The study calls for more standardized research methods to better understand whether microplastics meaningfully increase human and wildlife exposure to these co-pollutants.
The bioaccumulation effects of microplastics and associated organic pollutants in the aquatic environment
This review examined how microplastics in aquatic environments interact with organic pollutants through adsorption, affecting the bioaccumulation and toxicity of those pollutants in aquatic organisms due to the high hydrophobicity of microplastic surfaces.
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.
The chemical behaviors of microplastics in marine environment: A review
This review summarized interactions between microplastics and organic pollutants and metals in the marine environment, covering sorption behavior across polymer types, the role of degradation in altering sorption capacity, and global monitoring data on pollutant concentrations on marine plastics. The authors conclude that microplastic type, pollutant properties, and environmental conditions all strongly influence chemical accumulation on plastic surfaces.
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.
Adsorption behaviour and interaction of organic micropollutants with nano and microplastics – A review
This review analyzed the adsorption behavior of organic micropollutants — including pharmaceuticals, pesticides, and industrial chemicals — onto nano- and microplastics, finding that adsorption is governed by pollutant hydrophobicity, particle surface area, and aging state, and that microplastics can act as vectors delivering co-contaminants to aquatic organisms.

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.
