ClearAggregation Behavior of Particulate Plastics and Its Implications
This chapter reviews how microplastics aggregate with each other and with natural particles like sediment and algae in water, affecting their transport, fate, and biological availability. Heteroaggregation with natural colloids is more common than microplastic-to-microplastic clumping, which has important implications for how microplastics move through aquatic environments.
Heteroaggregation of nanoplastic particles in the presence of inorganic colloids and natural organic matter
Nanoplastics were found to heteroaggregate extensively with inorganic colloids and natural organic matter in both freshwater and marine conditions, altering their size, surface charge, and settling behavior compared to pristine particles. The study demonstrates that nanoplastic behavior in natural waters is dominated by interactions with other environmental constituents rather than the intrinsic properties of the plastic alone.
Hybrid modeling of hetero-agglomeration processes: a framework for model selection and arrangement
Researchers developed a hybrid modeling framework for hetero-agglomeration processes — the clumping together of different particle types — to better predict how microplastics interact with natural particles in aquatic environments. The framework helps select appropriate models for different environmental conditions and particle combinations.

Researchers reviewed nanoparticle heteroagglomeration with natural and synthetic suspended particulate matter in aquatic environments, examining how the kinetics of agglomeration between nanoplastics, manufactured nanomaterials, and SPM affect nanoparticle transport and risk assessment in river systems.
Interaction, Adhesion and Aggregation of Microplastic/Nanoplastic Particles: Effects of Plastic Polymer Type
This review examines how polymer type, particle size, shape, pH, ionic strength, and salt composition influence the interaction, adhesion, and aggregation behavior of microplastics and nanoplastics in aquatic and soil environments. The paper synthesizes findings on homoaggregation and heteroaggregation with natural and engineered nanoparticles, highlighting how aggregation affects particle transport and environmental fate.
A review of microplastics aggregation in aquatic environment: Influence factors, analytical methods, and environmental implications
This review examines how microplastics clump together in aquatic environments, a behavior called aggregation that affects where they end up and how available they are to organisms. Researchers evaluated the factors that influence aggregation, including water chemistry, particle size, and the presence of natural organic matter. The study identifies important gaps in field research and calls for standardized methods to better understand how aggregation shapes the environmental fate of microplastics.
Effect of the Surface Hydrophobicity–Morphology–Functionality of Nanoplastics on Their Homoaggregation in Seawater
Researchers found that nanoplastic surface hydrophobicity, morphology, and functional chemistry strongly govern homoaggregation behavior in aquatic environments, with more hydrophobic and functionalized particles forming larger, faster-settling aggregates that alter their environmental fate and bioavailability.
Heteroaggregation kinetics of oppositely charged nanoplastics in aquatic environments: Effects of particle ratio, solution chemistry, and interaction sequence
Researchers investigated how oppositely charged nanoplastics clump together (heteroaggregation) in water under varying pH, salt, and natural organic matter conditions, finding that electrostatic attraction drives aggregation but humic acid retards it more than sodium alginate, while the sequence and timing of chemical interactions also significantly alters the final aggregation behavior.
Statistical Thermodynamic Description of Heteroaggregation between Anthropogenic Particulate Matter and Natural Particles in Aquatic Environments
Researchers developed a thermodynamic model to describe how nanoparticles and microplastics aggregate with each other and with natural particles in aquatic environments. Understanding aggregation processes is critical for predicting how microplastics move through water systems and where they ultimately settle.

Researchers developed strategies for determining heteroaggregation attachment efficiencies of engineered nanoparticles with suspended particulate matter in aquatic environments, providing a practical roadmap for understanding nanoparticle fate in natural water systems.
Heteroaggregation, disaggregation, and migration of nanoplastics with nanosized activated carbon in aquatic environments: Effects of particle property, water chemistry, and hydrodynamic condition
Researchers studied how nanosized activated carbon interacts with positively and negatively charged nanoplastics under various water chemistry and hydrodynamic conditions. They found that aggregation behavior depended strongly on particle charge, pH, and the presence of natural organic matter like humic acid. The study suggests that interactions with engineered nanomaterials in aquatic environments can significantly influence how far nanoplastics travel, with implications for predicting their environmental fate.
Both nanoplastic and iron mineral types determine their heteroaggregation: Aggregation kinetics and interface process
Researchers measured how four types of nanoplastics aggregate with iron minerals and found that surface chemistry drives the outcome — with PMMA forming the strongest heteroaggregates and carboxyl-modified particles the weakest — and that electron transfer from nanoplastics to hematite partially reduces iron, with implications for aquatic iron cycling.
Influence of Shape on Heteroaggregation of Model Microplastics: A Simulation Study
This simulation study examined how the shape of microplastic particles (spheres vs. fibers vs. fragments) affects how they clump together (heteroaggregate) with natural organic matter in water. Particle shape influences how far microplastics travel, where they settle, and how available they are to aquatic organisms.
Flocculation with heterogeneous composition in water environments: A review
This review examines how particles of different compositions, including minerals, organic matter, microplastics, and biological material, clump together through flocculation in natural water environments. Researchers found that the mixed composition of these clusters significantly affects how pollutants are transported and deposited in rivers, estuaries, and oceans. Understanding flocculation processes is important for predicting how microplastics and other contaminants move through and settle in aquatic systems.
Sediment organic carbon dominates the heteroaggregation of suspended sediment and nanoplastics in natural and surfactant-polluted aquatic environments
Researchers found that sediment organic carbon plays a dominant role in the heteroaggregation of nanoplastics with suspended sediment particles, with surfactant pollution altering aggregation dynamics and influencing the environmental transport and fate of nanoplastics in aquatic systems.
Aquatic Aggregates as “Vector” for Microplastics
This review examines how microplastics interact with aquatic aggregates — clumps of organic matter, clay, and other particles formed through flocculation in natural waters. Aggregation affects microplastic transport by changing their effective density and size, influencing whether they sink, float, or remain suspended. Understanding these interactions is key to accurately predicting where microplastics end up in aquatic environments.
Nanoplastics Aggregation in Environment: Analytical Methods and Environmental Implications
This review examines how nanoplastics aggregate in the environment—clumping together or attaching to other particles—and how this affects their analysis and ecological impact. Aggregation changes how nanoplastics move through water and accumulate in organisms, complicating risk assessment for these extremely small plastic particles.
The environmental fate of nanoplastics: What we know and what we need to know about aggregation
Researchers systematically analyzed experimental studies on nanoplastic aggregation behavior, evaluating the environmental relevance of 377 solution chemistries and 163 particle models. The study found that commonly used polymer latex spheres do not accurately represent real-world nanoplastics, and suggests that incidentally produced nanoplastics may be more sensitive to heteroaggregation than previously expected.

Cotransport and deposition of biochar with different sized-plastic particles in saturated porous media
Researchers studied how biochar and plastic particles (nanoplastics and microplastics) mutually affect each other's transport through water-saturated sand, finding that small plastic particles enhanced biochar mobility while biochar consistently suppressed plastic particle transport across all sizes, due to heteroaggregation altering surface charge and steric interactions.

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.
Impact of iron/aluminum (hydr)oxide and clay minerals on heteroaggregation and transport of nanoplastics in aquatic environment
Researchers examined how polystyrene nanoplastics interact with nine different minerals in aquatic environments, finding that positively charged iron and aluminum (hydr)oxide minerals readily form aggregates with nanoplastics through electrostatic and hydrophobic forces, while humic acid and shifting pH significantly suppress this aggregation.
Further research on the impacts of humic acid in the aggregation of nanoplastics: The roles of molecular weight and surface functionalization
Researchers studied how humic acid — a natural compound found in soil and water — coats nanoplastic particles and changes how they clump together, finding that larger humic acid molecules create thicker coatings that keep nanoplastics suspended and dispersed rather than settling. This matters because dispersed nanoplastics travel farther through water systems and are more likely to be ingested by organisms.
