Exposure to Nanoplastics and Co-Contaminants in Foods and Environment: Threats to Human Health
Summary
This review summarizes how nanoplastics combine with other environmental contaminants, including persistent organic pollutants, antibiotics, and endocrine-disrupting chemicals, and what that means for food safety. Researchers found that nanoplastics can enhance the bioavailability and toxicity of co-contaminants due to their small size and high surface activity. The study underscores that assessing nanoplastic risks requires considering their role as carriers of other harmful substances.
Nanoplastics have emerged as significant global pollutants, drawing worldwide concern. Due to their small particle size, large specific surface area, and high surface activity, nanoplastics can combine with other environmental contaminants, including environmental nanoparticles, persistent organic pollutants, antibiotics, and endocrine-disrupting chemicals. This review summarizes recent progress on the environmental behavior of nanoplastics and their complex effects on food safety when co-exposed to various contaminants. These composite pollutants accumulate in foods and the environment, and are ultimately taken up by humans, posing potential toxic effects on human health. In the future, the interaction mechanisms between environmental NPs and various co-contaminants, as well as their transfer routes from food to humans, should be addressed.

Toxicological interactions of microplastics/nanoplastics and environmental contaminants: Current knowledge and future perspectives
This review examines how the combined presence of micro- and nanoplastics with other environmental contaminants like heavy metals, pesticides, and pharmaceuticals affects toxicity. Researchers found that plastic particles can alter the bioavailability and toxic effects of co-occurring pollutants, sometimes increasing harm to organisms, which complicates environmental risk assessment.
Microplastics as vectors for environmental contaminants in the food chain: Assessing the combined toxicological effects and bioavailability
This review examines how microplastics and nanoplastics act as carriers for environmental pollutants including heavy metals, organic chemicals, and microbial agents as they move through food chains. Researchers detail how polymer type, particle size, and environmental conditions influence the binding and release of these contaminants. The study highlights that the combined toxicity of microplastics together with the pollutants they carry may be greater than either would cause alone.
Nanoplastics as a Vehicle for Environmental Pollutants: A Hazard for Human Health
This review examines nanoplastics as environmental vectors for chemical pollutants, discussing how their high surface-area-to-volume ratio enables adsorption of heavy metals, pesticides, and persistent organic pollutants. The authors assess the evidence for nanoplastic-facilitated delivery of these co-contaminants to human tissues and call for dedicated nanoplastic toxicology studies.
Potential Health Risks of Micro-Nanoplastics and Persistent Organic Pollutants: A Review of Exposure Pathways and Toxic Effects
This review examines how micro- and nanoplastics can enhance the bioavailability of persistent organic pollutants through a Trojan horse effect, leading to combined inflammatory, cellular, and metabolic toxic effects that threaten human health beyond what either contaminant causes alone.
Toxic Chemicals and Persistent Organic Pollutants Associated with Micro-and Nanoplastics Pollution
Researchers reviewed how micro- and nanoplastics act as carriers for toxic chemical additives and persistent organic pollutants — like flame retardants and pesticides — making these contaminants more available and harmful once they enter food chains and human bodies. The review identifies major gaps in understanding how these chemicals detach from plastic particles inside living organisms and what health effects they cause.
