UV-induced aggregation of polystyrene nanoplastics: effects of radicals, surface functional groups and electrolyte
Summary
UV irradiation was found to increase the aggregation of polystyrene nanoplastics to varying degrees depending on surface functional groups and electrolyte conditions, with free radicals playing a key role. Understanding aggregation behavior is important for predicting how nanoplastics behave and settle in aquatic environments.
UV irradiation increased the aggregation of polystyrene nanoplastics to different extents depending on the surface functional groups and electrolyte species.

Aggregation kinetics of UV irradiated nanoplastics in aquatic environments
Researchers compared the aggregation behavior of fresh versus UV-aged polystyrene nanoplastics under various aquatic conditions. They found that UV aging altered the surface chemistry of nanoplastics, making them more stable in water and less likely to aggregate, which means they could remain suspended and bioavailable for longer periods. The study suggests that weathered nanoplastics may behave very differently from fresh particles in the environment, complicating risk assessments.
UV/ozone induced physicochemical transformations of polystyrene nanoparticles and their aggregation tendency and kinetics with natural organic matter in aqueous systems
Researchers weathered polystyrene nanoparticles with UV light and ozone and then tested their aggregation behavior in waters containing humic acid, lysozyme, and alginate, finding that weathering-induced oxygen-containing surface groups significantly altered aggregation kinetics in ways strongly dependent on which organic molecules were present.
Aggregation kinetics of different surface-modified polystyrene nanoparticles in monovalent and divalent electrolytes
Researchers investigated how surface chemistry and morphology affect the clumping behavior (aggregation kinetics) of polystyrene nanoplastics in water, finding that surface charge and functional groups strongly govern stability, while dissolved organic matter can either inhibit or promote aggregation depending on concentration and whether mono- or divalent ions are present.
Aggregation behavior of polystyrene nanoplastics: Role of surface functional groups and protein and electrolyte variation
Researchers studied how different surface coatings on polystyrene nanoplastics affect their tendency to clump together in water containing proteins and salts. They found that the type of surface functional group significantly changed how the particles aggregated, with proteins and electrolytes playing important roles in the process. The study helps explain how nanoplastics behave and transform as they move through natural water systems.
UV-weathering affects heteroaggregation and subsequent sedimentation of polystyrene microplastic particles with ferrihydrite
Researchers studied how UV weathering alters the heteroaggregation and sedimentation behaviour of 1-micrometre polystyrene microplastic particles with ferrihydrite (an iron oxy-hydroxide common in natural waters). They found that UV weathering changed the surface charge and properties of polystyrene particles, significantly affecting their aggregation with ferrihydrite at neutral pH and their subsequent removal from the water column by sedimentation.
