Analytical approaches for exploring the role of micro and nanoplastics as carriers of non-phthalate plasticizers and environmental pollutants.
AI summary Read the abstract
Tiny plastic particles floating around our environment aren't just harmless debris—they can act like sponges, soaking up toxic chemicals and heavy metals from their surroundings, then release them elsewhere, including potentially in our food and bodies. This review of existing research highlights this "Trojan horse" effect and points out that scientists still lack standardized, reliable methods to measure exactly how much of these harmful chemicals microplastics carry, making it harder to fully understand the risks to our health. Bottom line: more consistent research is needed before we can accurately assess how much danger these plastic particles pose as chemical delivery veh
Micro and nanoplastics (MNPs) are widely distributed in the environment and can no longer be considered as inert debris. In fact, they behave as chemically active materials that may pose a "triple threat" to ecosystems. This arises from both endogenous additives, including non-phthalate plasticizers (NPPAs) incorporated during plastic manufacturing, exogenous contaminants, including persistent organic pollutants (POPs) and heavy metals, which are taken up from the surrounding environment, and the MNP particles themselves. This review focused on the so-called "Trojan horse" effect of MNPs, emphasizing their ability to transport and release associated chemical additives, as NPPAs, and environmental pollutants. Current analytical methodologies for the determination of these associated compounds will be evaluated, paying attention to challenges such as background contamination, matrix effects and the need for high-resolution mass spectrometry. Despite the high number of studies in this field, important gaps remain, especially regarding the lack of standardized methodologies and the limited use of environmentally relevant experimental conditions. Thus, key research needs are outlined to better support future regulatory frameworks, with particular emphasis on improving the understanding of sorption-desorption processes and the potential interactions among these contaminants within both environmental and agri-food systems.

Micro- and Nanoplastics in the Environment: Analytical Approaches, Environmental Fate, Life Cycle, and Remediation Strategies—A Scoping Review
AI summary Read the abstract
This review pulls together existing research on tiny plastic particles (microplastics and even smaller nanoplastics) that are now found almost everywhere, in water, soil, air, and even our food. The big takeaway: scientists still lack standardized methods to detect and measure these particles, especially the smallest ones, which makes it hard to fully understand how much we're exposed to and what health risks they carry, including their ability to carry other harmful chemicals into our bodies. This matters because better detection tools and cleanup strategies are needed before we can accurately assess how these ubiquitous particles affect human health.
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.
What Does the “Trojan Horse” Carry? The Pollutants Associated with Microplastics/Nanoplastics in Water Environments
AI summary Read the abstract
Microplastics act as tiny "Trojan horses" in water, carrying toxic chemical additives like plasticizers, flame retardants, and stabilizers that leach out as the plastic breaks down. These additives can build up in living organisms and pose risks to human health. This review maps out what we currently know about these hitchhiking pollutants and identifies major gaps in our understanding of how they behave in aquatic environments.
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.
Transport of micro- and nanoplastics in the environment: Trojan-Horse effect for organic contaminants
AI summary Read the abstract
This review examines how micro- and nanoplastics act as carriers for organic contaminants in the environment, a phenomenon known as the Trojan-Horse effect. Researchers found that these tiny plastic particles can adsorb both their own chemical additives and external pollutants, transporting them across ecosystems through water, air, and soil. The study suggests that the ability of microplastics to concentrate and deliver harmful chemicals to organisms may amplify their environmental and health impacts beyond the effects of the plastic particles alone.
