The study raises important questions about a previously underappreciated pathway through which plastic pollution could affect public health.
The hidden risk of microplastic-associated pathogens in aquatic environments
This review examines the overlooked risk that microplastics in water can serve as vehicles for disease-causing bacteria and other pathogens. Microplastics provide a surface where harmful microorganisms can grow, survive longer, and travel farther than they would on their own. This means microplastic pollution in lakes, rivers, and oceans could increase the risk of waterborne infections in people who swim in, drink from, or eat seafood from contaminated water.

This review examines how microplastics may influence the dispersal of small organisms, including bacteria, fungi, viruses, and insects, by serving as physical carriers across ecosystems. Researchers describe how biofilms that form on microplastic surfaces can harbor and transport pathogenic microorganisms to new locations. The study identifies this as an underexplored area with significant implications for disease ecology and biosecurity.
Microplastics as Vectors of Chemicals and Microorganisms in the Environment
This review examines microplastics as vectors for chemicals and microorganisms in the environment, discussing the 'plastisphere' concept, hydrophobic surface interactions that facilitate pollutant adsorption, biofilm formation, and the mechanisms by which microplastics transport contaminants and pathogens through aquatic systems.
From wastewater discharge to the beach: Survival of human pathogens bound to microplastics during transfer through the freshwater-marine continuum
Researchers investigated how human pathogens survive on microplastic surfaces as they travel from wastewater treatment plants through freshwater into marine environments. They found that the biofilm environment on plastic surfaces helped bacteria like E. coli and Enterococcus faecalis persist longer during transitions between water types compared to bacteria in the surrounding water. The study suggests that microplastics may facilitate the environmental spread of pathogens by providing a protective habitat during transport.
Micro(nano)plastics: Unignorable vectors for organisms
This review examines the role of micro- and nanoplastics as vectors for contaminants — including heavy metals, organic pollutants, and pathogens — in aquatic and terrestrial environments. It synthesizes evidence on how plastic particles can adsorb, transport, and release harmful substances, amplifying their ecological and health risks beyond the physical effects of the particles alone.
Viral diversity and potential environmental risk in microplastic at watershed scale: Evidence from metagenomic analysis of plastisphere
Metagenomic analysis of plastisphere communities on microplastics collected from five freshwater sites revealed diverse viral communities including phages and potential animal pathogens, with plastic-associated viromes differing from those in surrounding water. The study identifies microplastics as previously overlooked carriers of viral diversity and potential environmental health risks in aquatic ecosystems.
Microplastics as vectors of chemical contaminants and biological agents in freshwater ecosystems: Current knowledge status and future perspectives
This review examines how microplastics in freshwater ecosystems act as carriers for chemical pollutants and harmful microorganisms. Researchers found that pollutant concentrations on microplastic surfaces can be up to six times higher than in surrounding water, amplifying exposure risks for aquatic life and potentially humans. The findings highlight that microplastics are not just a pollution problem themselves but also a vehicle that spreads other contaminants through the food web.

Survival of human pathogens bound to microplastics during transfer through the freshwater-marine continuum: from wastewater discharge to the beach
Researchers tracked survival of E. coli, E. faecalis, and P. aeruginosa colonizing polyethylene microplastics as particles were transferred through a series of mesocosms simulating downstream transport from wastewater effluent through freshwater, estuary, seawater, and beach sand. All three pathogens survived the full environmental transition sequence in the plastisphere, with higher bacterial concentrations on microplastics than on glass controls, though die-off rates did not differ by substrate, demonstrating microplastics' potential to extend pathogen persistence across environmental boundaries.
