ClearBiofilm on microplastics in aqueous environment: Physicochemical properties and environmental implications
This review examines how bacteria and other microorganisms form sticky films called biofilms on microplastic surfaces in water. These biofilms change how microplastics move through the environment and increase their ability to absorb pollutants like heavy metals, pesticides, and antibiotics. Biofilm-coated microplastics may also carry harmful bacteria, making them a greater potential health risk than clean microplastic particles.
Exaggerated interaction of biofilm-developed microplastics and contaminants in aquatic environments
Researchers found that biofilm formation on microplastic surfaces exaggerates the adsorption and vector capacity for co-contaminants in aquatic environments, with biofilm-coated MPs showing substantially higher uptake of contaminants than pristine MPs.
Microplastics as vectors of contaminants
This review highlights the emerging role of microplastics as carriers of biological and chemical contaminants in water environments. Researchers note that while microplastic pollution is increasingly well-documented, the interactions between contaminants adsorbed onto microplastic surfaces and aquatic organisms remain poorly understood. The study stresses the need for further investigation into how microplastics may facilitate the transport and bioavailability of pollutants.
Colonization characteristics and surface effects of microplastic biofilms: Implications for environmental behavior of typical pollutants
This review examines how bacteria colonize microplastic surfaces in water, forming biofilms that change how the plastics behave in the environment. These biofilms alter the surface properties of microplastics and affect how they absorb and transport heavy metals and other pollutants. Understanding biofilm formation on microplastics is important because it can make the particles more dangerous by concentrating toxic substances that could eventually enter the food chain.
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.
Microplastics–biofilm in aquatic ecosystem: Formation, pollutants complexation, greenhouse gas emission and ecotoxicology
This review examines how microplastics in water develop biofilms (layers of bacteria and other microorganisms) that make them stickier and more capable of absorbing harmful pollutants. These microplastic-biofilm combinations can carry heavy metals, organic contaminants, and disease-causing microorganisms through aquatic environments, and even contribute to greenhouse gas emissions. The findings are relevant to human health because contaminated microplastics with biofilms are more likely to carry toxic substances into the food chain.
Microplastics: A Potential Vector for Pathogens in Aquatic Ecosystems
This review examines the evidence that microplastics act as vectors for pathogens in aquatic environments, summarizing how the large surface area and persistence of microplastics promote pathogen adhesion, biofilm formation, and transport of harmful microorganisms.
The role of microplastics biofilm in accumulation of trace metals in aquatic environments
This review examines how biofilms that form on microplastics in aquatic environments enhance the accumulation of trace metals from surrounding water. Researchers found that microorganisms colonizing plastic surfaces produce extracellular substances that facilitate metal sorption, effectively turning microplastics into concentrated carriers of metallic contaminants. The study highlights the dual pollution risk posed by microplastics serving as both physical pollutants and vehicles for toxic metal transport in waterways.
Microplastic-Associated Biofilms and Their Role in the Fate of Microplastics in Aquatic Environment
This review examines how microbial biofilms attached to microplastics in aquatic environments mediate the accumulation and transfer of chemical pollutants, exploring how the 'plastisphere' community influences the fate and ecotoxicological impact of microplastics and co-contaminants.
Physicochemical behavior and ecological risk of biofilm-mediated microplastics in aquatic environments
This review explores how biofilm formation on microplastics in water environments changes their physical and chemical behavior, potentially increasing their ecological risks. Researchers found that biofilm-coated microplastics more readily absorb pollutants and antibiotic resistance genes, and may disrupt gut microbiota in organisms that ingest them. The findings suggest that the biological aging of microplastics in nature makes them more dangerous than freshly produced particles.
Impact of Biofilm Formation on Microplastic Behaviour in Aquatic Environments: An Comprehensive Review.
This review examines how biofilms — communities of microorganisms that coat microplastics — change the behavior of plastic particles in aquatic environments, affecting how they move, sink, and interact with ecosystems. Understanding biofilm formation on microplastics is key to predicting where these particles end up and what risks they pose to water quality and aquatic life.

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.
Research progress on the role of biofilm in heavy metals adsorption-desorption characteristics of microplastics: A review
This review examines how biofilm formation on microplastics in aquatic environments modifies their properties and changes how they adsorb and release heavy metals. Researchers found that biofilm-covered microplastics behave significantly differently than bare microplastics, which has important implications for understanding the combined environmental risks of microplastics and heavy metal contamination.
Biofilm formation on polyethylene microplastics and their role as transfer vector of emerging organic pollutants
This study examined how bacteria form biofilms on polyethylene microplastics and whether those biofilms help transport organic pollutants like common pharmaceuticals and pesticides. Researchers found that the bacterium Pseudomonas aeruginosa readily colonized microplastics, and the presence of contaminants in the water altered biofilm characteristics. The findings suggest that microplastics in waterways may act as carriers that help spread pharmaceutical and chemical pollutants through aquatic environments.
Biofilm formation and its implications on the properties and fate of microplastics in aquatic environments: A review
Researchers reviewed how microplastics in water attract and support communities of bacteria and other microorganisms that form biofilms — living coatings that alter the plastic particles' movement, help them carry pathogens, and affect how toxic chemicals attached to the plastic are absorbed by living things. Understanding this "plastisphere" ecosystem is critical for predicting where microplastics go and how harmful they become.
Recent advances in the relationships between biofilms and microplastics in natural environments
