ClearReviewing the role of microplastics as carriers for microorganisms in absorbing toxic trace elements
This review examines how microplastics serve as carriers for both harmful bacteria and toxic metals in the environment. Bacteria colonize microplastic surfaces and form biofilms, which can concentrate dangerous trace elements and help spread pathogens to new areas. This dual role as a transport vehicle for both chemical and biological contaminants increases the potential risk to human health through contaminated water and food.
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.
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.

Interactions Between Microplastics and Heavy Metals in Aquatic Environments: A Review
This review examines how microplastics interact with heavy metals in water, with a particular focus on the role that microorganisms play in driving these interactions. Bacteria that colonize microplastic surfaces can change how metals bind to and release from the particles, potentially increasing their toxicity. The combined threat of microplastics and heavy metals to aquatic ecosystems and human health through seafood consumption is a growing concern that needs more research.
Biofilm 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.
Adsorption of heavy metals by biofilm-coated microplastics in aquatic environments: Mechanisms, isotherm and kinetic processes, and influencing factors
This review synthesizes research on how biofilms—microbial coatings that naturally form on microplastics in water—alter the particles' ability to absorb heavy metals like lead, copper, and cadmium, finding that biofilmed microplastics generally adsorb more metal than bare plastic and that electrostatic forces and surface complexation are the dominant mechanisms. This matters because microplastics coated in both biofilm and toxic metals may deliver a double dose of contamination to organisms that ingest them. The review identifies key gaps, including how competitive metal mixtures and shifting biofilm composition over time affect this combined pollution risk.
Biofilm-Developed Microplastics As Vectors of Pollutants in Aquatic Environments
This review examines how biofilms that form on microplastics in aquatic environments change their ability to absorb and transport pollutants. Researchers found that biofilm-coated microplastics can absorb more contaminants than clean microplastics and serve as vectors that transfer both pollutants and potentially harmful microorganisms through aquatic ecosystems.
The Unseen Threat of the Synergistic Effects of Microplastics and Heavy Metals in Aquatic Environments: A Critical Review
This review examines how microplastics and heavy metals interact in water environments, finding that microplastics can attract and concentrate toxic metals on their surfaces through various chemical forces. This combination effect is a concern for human health because contaminated microplastics carrying heavy metals can be consumed through seafood, delivering a double dose of pollutants.

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.
The bioaccessibility of adsorped heavy metals on biofilm-coated microplastics and their implication for the progression of neurodegenerative diseases
Researchers examined how microplastics coated with natural biofilms can carry heavy metals into the body and what that might mean for human health. The biofilm layer changes the surface chemistry of microplastics, making them better at attracting and holding onto toxic metals that can then become accessible during digestion. The study raises concerns about the combined exposure to microplastics and heavy metals as a potential contributing factor to long-term health issues.

The findings highlight the need for more research on the long-term and multigenerational effects of these combined pollutants.
