Microplastics as vectors of other contaminants: Analytical determination techniques and remediation methods
AI summary Read the abstract
This review examines how microplastics act as carriers for other pollutants, absorbing harmful organic and inorganic chemicals from the environment. It covers the latest methods for detecting and identifying microplastics in different settings, as well as promising cleanup approaches like microbial degradation. The findings underscore that microplastics may be more dangerous than the plastic itself because of the toxic hitchhikers they carry into the food chain and water supply.
The ubiquitous and persistent presence of microplastics (MPs) in aquatic and terrestrial ecosystems has raised global concerns due to their detrimental effects on human health and the natural environment. These minuscule plastic fragments not only threaten biodiversity but also serve as vectors for contaminants, absorbing organic and inorganic pollutants, thereby causing a range of health and environmental issues. This review provides an overview of microplastics and their effects. This work highlights available analytical techniques for detecting and characterizing microplastics in different environmental matrices, assessing their advantages and limitations. Additionally, this review explores innovative remediation approaches, such as microbial degradation and other advanced methods, offering promising prospects for combatting microplastic accumulation in contaminated environments. The focus on environmentally-friendly technologies, such as the use of microorganisms and enzymes for microplastic degradation, underscores the importance of sustainable solutions in plastic pollution management. In conclusion, this article not only deepens our understanding of the microplastic issue and its impact but also advocates for the urgent need to develop and implement effective strategies to mitigate this critical environmental challenge. In this context, the crucial role of advanced technologies, like quantitative Nuclear Magnetic Resonance spectroscopy (qNMR), as promising tools for rapid and efficient microplastic detection, is emphasized. Furthermore, the potential of the enzyme PETase (polyethylene terephthalate esterase) in microplastic degradation is examined, aiming to address the growing plastic pollution, particularly in saline environments like oceanic ecosystems. These innovations offer hope for effectively addressing microplastic accumulation in contaminated environments and minimizing its adverse impacts.

A comprehensive review on microplastics as vectors of chemical and biological pollutants
AI summary Read the abstract
This review pulls together existing research showing that tiny plastic particles (microplastics) don't just pollute on their own — they can act like sponges, soaking up other harmful chemicals and even microbes from their surroundings and carrying them into the environment and food chain. This matters because plastic-bound pollutants appear to be more toxic and more likely to build up in living organisms than those same pollutants floating freely, raising concerns about how much these "hitchhiking" toxins could affect human health through contaminated food and water. The authors call for more real-world testing to better understand these risks and guide future safety regulations.
Microplastics with adsorbed contaminants: Mechanisms and Treatment
AI summary Read the abstract
This review examines how microplastics adsorb environmental contaminants including heavy metals, organic pollutants, and pathogens, and surveys treatment methods for removing contaminated microplastics from water. Researchers found that microplastics can act as vectors for hazardous substances, potentially increasing their bioavailability and toxicity in aquatic ecosystems. The study evaluates emerging remediation technologies and highlights the complex environmental risks posed by microplastics carrying adsorbed pollutants.
Source, transport, and toxicity of emerging contaminants in aquatic environments: A review on recent studies
AI summary Read the abstract
This review examines emerging contaminants in water, with a focus on how microplastics act as carriers for other pollutants due to their strong ability to absorb chemicals. When microplastics carry these hitchhiking pollutants, the combined effect on aquatic organisms can be amplified thousands of times as they move up the food chain. The findings highlight how microplastic pollution does not just add plastic to the environment but also concentrates and transports other harmful chemicals toward humans.

AI summary Read the abstract
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.
Microplastics in the environment: analytical chemistry methods, sorption materials, risks and sustainable solutions
AI summary Read the abstract
This review covers the full picture of microplastic pollution, from how scientists detect and measure these particles to how they carry other pollutants and affect living organisms. The authors highlight that microplastics act as tiny sponges that absorb harmful chemicals like pharmaceuticals and pesticides, then release them inside organisms that ingest the particles. The review calls for more standardized testing methods and sustainable solutions to reduce both microplastic pollution and its risks to human health.
