ClearNanoplastics 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.
A simple methodology for in situ study of microplastics’ aggregation
This study developed a straightforward lab method to measure how microplastics clump together (aggregate) under different water chemistry conditions — including varying pH, dissolved organic matter, and stormwater composition — and after UV weathering. Key findings: weathered microplastics aggregate much more readily than fresh ones, especially in stormwater, meaning aged plastics in the environment tend to form larger clumps that settle out differently and interact with aquatic organisms differently. Understanding aggregation behavior is essential for predicting where microplastics end up in rivers and lakes and how bioavailable they are.
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.
Aggregation 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.
Aggregation kinetics of microplastics in aquatic environment: Complex roles of electrolytes, pH, and natural organic matter
Researchers found that the aggregation behavior of polystyrene microplastics in water was strongly influenced by pH, ionic strength, and the presence of natural organic matter, with divalent cations like calcium and magnesium promoting aggregation. Understanding aggregation kinetics is critical for predicting how microplastics partition between suspended and settled states in natural water bodies.
Environmental factors-mediated behavior of microplastics and nanoplastics in water: A review
This review examines how environmental conditions such as pH, salt levels, and organic matter influence how microplastics and nanoplastics behave in water. The study found that these factors significantly affect whether tiny plastic particles clump together or stay dispersed, which in turn determines how far they travel and how available they are for organisms to ingest.
Sedimentation behavior of aggregated microplastics: Influence of particle size and water constituents in environmental waters
Laboratory experiments investigated how aggregation of microplastics with sediments and organic matter affects their sinking rates in water, finding that aggregate composition strongly influences settling velocity. These findings improve models predicting whether microplastics sink to the seafloor or remain suspended in the water column.
Heterogeneous aggregation of microplastics and mineral particles in aquatic environments: Effects of surface functional groups, pH, and electrolytes
Researchers studied how microplastics clump together with soil and rock minerals in water, finding that positively charged minerals bound to plastic particles nearly three times more effectively than clay minerals, and that low pH and calcium ions dramatically accelerated aggregation. Understanding these dynamics helps predict where microplastics will settle or stay suspended in rivers, lakes, and aquifers.
Microplastics and Nanoplastics in Aquatic Environments: Aggregation, Deposition, and Enhanced Contaminant Transport
This review examined the aggregation, deposition, and transport of microplastics and nanoplastics in aquatic environments, synthesizing how particle properties and water chemistry govern their fate and mobility in rivers, lakes, and oceans.
Aggregation of microplastics and clay particles in the nearshore environment: Characteristics, influencing factors, and implications
Researchers studied how microplastics interact with natural clay particles in coastal waters, examining how factors like salinity, pH, and particle properties influence their aggregation behavior. They found that microplastics readily form clusters with clay particles, which changes how they settle and move through nearshore environments. Understanding this aggregation process is important for predicting where microplastics end up in coastal ecosystems and their potential exposure to marine organisms.
Behavior of Microplastics in Inland Waters: Aggregation, Settlement, and Transport
This review examined how microplastics aggregate, settle, and are transported horizontally in inland waters, covering the influence of particle properties (size, density, shape) and environmental factors (microorganisms, hydraulic conditions, sediment characteristics) on their fate.

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.
The difference of aggregation mechanism between microplastics and nanoplastics: Role of Brownian motion and structural layer force
The aggregation mechanisms of 100-nm and 1-micrometer polystyrene particles were compared under different water chemistry conditions to understand how microplastics and nanoplastics behave differently in aquatic environments. The study found distinct aggregation pathways between the two size classes, driven by differences in electrostatic forces and surface properties.
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.
