Sorption Behavior of Organic Pollutants on Biodegradable and Nondegradable Microplastics: pH Effects
This study tested how water pH affects the adsorption of chlorinated phenols, polycyclic aromatic hydrocarbons, and halogenated benzenes onto seven types of microplastics — including biodegradable bioplastics. At neutral pH (7), microplastics bound chlorinated phenols most strongly, while PAH and halogenated benzene adsorption was pH-independent. The findings matter because they show that even biodegradable plastic alternatives can carry toxic co-contaminants in freshwater systems, complicating the environmental safety case for bioplastics.

Sorption Behavior and Mechanisms of Organic Contaminants to Nano and Microplastics
This review summarizes the sorption mechanisms by which organic contaminants bind to nano and microplastics, including partitioning, surface sorption via hydrogen bonding and pi-pi interactions, and pore filling. Solution chemistry factors like pH, ionic strength, and dissolved organic matter all influence how strongly contaminants adsorb to plastic surfaces.

Researchers evaluated the adsorption and desorption behavior of polychlorinated biphenyls (PCBs) onto polystyrene, polyethylene, and polyethylene terephthalate microplastics of varying sizes in marine water/sediment systems. Results showed that polymer type and particle size influenced PCB binding capacity, with microplastics acting as potential vectors for transferring persistent organic pollutants to marine biota through the food chain.
Adsorption behavior of organic pollutants and metals on micro/nanoplastics in the aquatic environment
This review examines how micro- and nanoplastics in aquatic environments adsorb organic pollutants and metals onto their surfaces, effectively acting as carriers for other contaminants. Researchers found that environmental factors like pH, salinity, and aging of the plastic significantly influence this sorption behavior. The findings raise concerns that microplastics may increase the bioavailability and toxicity of chemical pollutants in waterways.
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.

Modelling of the adsorption of chlorinated phenols on polyethylene and polyethylene terephthalate microplastic
This study modeled how chlorinated phenols — toxic water pollutants — stick to polyethylene and polyethylene terephthalate microplastics sourced from personal care products. The findings suggest microplastics can act as carriers for harmful chemicals in aquatic environments, potentially concentrating toxins and delivering them to organisms that ingest the particles.
Environmental Microplastics as Vectors of Non-Polar Organic Pollutants in Drinking Water
Researchers investigated whether microplastics in drinking water can absorb and carry harmful organic pollutants like benzo-a-pyrene, a known carcinogen. They found that microplastics oxidized by UV light had a significant capacity to concentrate these pollutants from the surrounding water. The study raises concerns about a dual risk from microplastics in drinking water -- both from the plastic particles themselves and from the toxic chemicals they can carry.
Interactions of Trihalomethanes (THMs) and Haloacetic Acids (HAAs) with PVC and PE Microplastics in Water
Microplastic particles remaining in treated drinking water can adsorb chlorination byproducts called trihalomethanes (THMs), potentially acting as vectors that deliver these cancer-associated chemicals into the body. Lab tests showed PVC microplastics adsorbed THMs at up to 18 micrograms per gram, while polyethylene showed little uptake, and weathered plastics behaved differently from virgin material — findings with direct relevance to drinking water safety and the regulation of plastic in water distribution systems.

Researchers tested how three common microplastics — PLA, PET, and PVC — absorb radioactive cesium-137 from water, finding that pH, temperature, and competing ions all affect how much cesium sticks to each plastic. This matters because microplastics can act as carriers for radioactive contaminants, potentially transporting them through aquatic environments.
Effect of microplastics on the adherence of coexisting background organic contaminants to natural organic matter in water
Researchers examined how microplastics affect the binding of organic contaminants (PCBs and hydroxy PCBs) to humic acid in water, finding that microplastics caused contaminants to migrate from humic acid to plastic surfaces. This redistribution effect could alter the bioavailability and environmental risk of co-occurring organic pollutants.
Microplastics as potential bisphenol carriers: role of adsorbents, adsorbates, and environmental factors
Laboratory experiments showed that four common microplastic types — polystyrene, polypropylene, polyamide, and PVC — all readily adsorb bisphenols (BPA, BPB, BPF, BPS), with polyamide showing the highest capacity. Adsorption was strongly influenced by polymer surface chemistry, bisphenol hydrophobicity, temperature, and salinity. Because bisphenols are potent endocrine disruptors, microplastics acting as their environmental carriers could amplify human and wildlife exposure through contaminated seafood and drinking water.
Adsorption of perfluoroalkyl substances on polyamide microplastics: Effect of sorbent and influence of environmental factors
Researchers studied how perfluoroalkyl substances (PFAS), a group of persistent industrial chemicals, bind to polyamide microplastics in water. They found that smaller microplastic particles absorbed dramatically more PFAS than larger ones, and that water chemistry conditions like pH and salinity influenced the process. The findings suggest microplastics can concentrate harmful chemicals and potentially increase human and wildlife exposure to PFAS in contaminated environments.
