ClearThe 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.
The sorption behaviour of amine micropollutants on polyethylene microplastics – impact of aging and interactions with green seaweed
Researchers studied how long-term aging of polyethylene microplastics changes their ability to bind organic pollutants (amine micropollutants), and how interactions with green seaweed affect this process. Aged microplastics showed different sorption behavior than fresh ones, which has implications for how effectively they transport contaminants through aquatic food webs.
Induced aging, structural change, and adsorption behavior modifications of microplastics by microalgae
Researchers found that microalgal biofouling caused more significant aging and surface degradation of microplastics compared to river microbial biofouling over a 30-day period. The study suggests that algae-induced aging substantially enhances the ability of polyethylene and PVC microplastics to adsorb organic pollutants like bisphenol analogues, increasing their potential to transport contaminants in the environment.
Change in adsorption behavior of aquatic humic substances on microplastic through biotic and abiotic aging processes
Researchers found that both UV irradiation and microbial aging of polyethylene microplastics significantly altered their surface chemistry, changing how aquatic humic substances adsorb onto the plastic surface and highlighting the importance of weathering state in assessing microplastic-contaminant interactions.
Microplastics and organic contaminants: Investigation of the sorption process on different polymer types
Researchers investigated sorption of organic contaminants onto microplastics collected from environmental samples, finding that real-world MPs had different sorption capacities than laboratory-prepared particles due to surface aging, biofouling, and co-sorption of natural organic matter.

Researchers studied interactions between microplastics and freshwater microalgae, finding that microplastics can physically attach to algal cells to form hetero-aggregates, altering both particle behavior and algal physiology.
The Inhibition of Microcystin Adsorption by Microplastics in the Presence of Algal Organic Matters
Researchers found that polyethylene, polystyrene, and polymethyl methacrylate microplastics can adsorb microcystin MC-LR from water, but the presence of algal intracellular organic matter (IOM) reduced this adsorption by up to 22.7% due to competitive binding, suggesting that microplastic uptake of harmful natural toxins is likely overestimated in realistic aquatic conditions.
Impact of microalgal biomass and microplastics on the sorption behaviour of pesticides in soil: a comparative study
Researchers examined how microalgal biomass interacts with microplastics to influence pesticide sorption behavior, finding that algal exudates coating MP surfaces altered their affinity for pesticides and affected the overall fate of pesticide-MP complexes in water.
Agglomeration of nano- and microplastic particles in seawater by autochthonous and de novo-produced sources of exopolymeric substances
Nano- and microplastic particles in seawater were found to readily form agglomerates with naturally produced exopolymeric substances, altering their surface properties, size, and sinking behavior compared to pristine particles. The study demonstrates that natural organic matter in seawater fundamentally changes how plastic particles behave and interact with marine organisms and sediments.
Effects of organic matter on interaction forces between polystyrene microplastics: An experimental study
Researchers examined how organic matter in seawater affects the aggregation and adhesion forces between polystyrene microplastics, finding that organic coatings alter surface interaction forces in ways that influence whether microplastics clump together and sink or remain dispersed in the water column.
Interplay of plastic pollution with algae and plants: hidden danger or a blessing?
Researchers tested the ability of three microalgae species to remove microplastics from water through bioadhesion, finding that all three species could adsorb particles onto their surfaces. Removal efficiency depended on particle size, surface charge, and algae cell morphology.
Interactions between polypropylene microplastics (PP-MPs) and humic acid influenced by aging of MPs
Researchers examined how aging affects polypropylene microplastic interactions with humic acid, finding that aged microplastics with increased surface oxygen groups showed stronger adsorption of humic acid compared to pristine particles, altering their environmental behavior.
The release inhibition of organic substances from microplastics in the presence of algal derived organic matters: Influence of the molecular weight-dependent inhibition heterogeneities
This study found that algae-derived organic matter in water affects the release of chemicals from microplastics, with larger molecular weight compounds having a greater inhibitory effect. Understanding these interactions is important for predicting how microplastics behave in natural water environments and the potential release of toxic additives.
A critical review of interactions between microplastics, microalgae and aquatic ecosystem function
This review of microplastic-microalgae interactions found that microplastics form distinct epiplastic algal communities that differ from surrounding water communities, and that the interactions are bidirectional — MP properties affect algal physiology while algal surface coatings alter MP behavior and fate.
