Microplastics as Vectors of PFAS: Adsorption Mechanisms, Environmental Fate, and Toxicological Implications
AI summary Read the abstract
This review examined how microplastics act as vectors for PFAS—so-called forever chemicals—by adsorbing and transporting these compounds through aquatic and terrestrial environments to increase combined toxic burden. The co-exposure risk is particularly concerning for human health because both microplastics and PFAS are persistent, and their interaction may amplify systemic toxicity beyond what either pollutant causes alone.
The pervasive occurrence of per- and polyfluoroalkyl substances (PFAS) and microplastics (MPs) in aquatic and terrestrial environments has raised growing concern due to their persistence, mobility, and combined toxicological effects. This review synthesizes updated...

Combined Toxicity of PFAS and Microplastics in Aquatic Ecosystems: Synergistic, Additive, and Antagonistic Interactions
AI summary Read the abstract
Researchers reviewed the combined toxicity of PFAS and microplastics in aquatic ecosystems, finding that while synergistic interactions receive the most attention, additive and antagonistic outcomes are also common and depend on PFAS congener, polymer type, particle size, and species—warning against treating synergy as the default response and calling for standardized mixture-based exposure protocols to enable ecologically realistic risk assessment.
Ecological Effects of Chemical Contaminants Adsorbed to Microplastics
AI summary Read the abstract
Researchers reviewed how chemical contaminants that bind to microplastics — including pesticides and heavy metals — affect aquatic and soil organisms, finding that microplastics can both concentrate toxins and amplify their biological impact. This so-called Trojan horse effect may make microplastic pollution more ecologically harmful than the plastic alone would suggest.
Ecological Effects of Chemical Contaminants Adsorbed to Microplastics
AI summary Read the abstract
Microplastics act as vectors for adsorbed chemical contaminants including pesticides, heavy metals, and persistent organic pollutants, amplifying their transport and bioavailability in aquatic and soil ecosystems. The combined exposure to plastic particles and their chemical cargo poses greater ecotoxicological risks than either contaminant class alone.
Research Gaps and Future Directions for Addressing Microplastics and PFAS: Impacts in Aquatic Environments
AI summary Read the abstract
This review identifies critical knowledge gaps in understanding how microplastics and PFAS (forever chemicals) interact and cause harm in aquatic environments after more than seven decades of production. Addressing these gaps is urgent because both contaminants persist indefinitely, accumulate in living organisms, and are now detectable in virtually every aquatic environment on Earth.
Introduction to Microplastics: Origin, Environmental Pathways, and Impacts on Ecosystems and Human Health
AI summary Read the abstract
Researchers introduced the origins, environmental transport pathways, and ecosystem impacts of microplastics, tracing how the non-biodegradable nature of plastics combined with poor waste management has driven pollution of terrestrial, aquatic, and human biological systems.
