Human and ecological health effects of nanoplastics: May not be a tiny problem
Summary
This review examined the health effects of nanoplastics in humans and ecosystems, finding that while direct human evidence is limited, nanoplastic particles cross biological barriers more readily than larger fragments and trigger oxidative stress, inflammation, and endocrine disruption in animal models, suggesting the problem is far from trivial.
Nanoplastics (NPs) are present in food, soil, water, air and personal care products, resulting in concern regarding exposure and potential adverse effects. NPs principally arise from the degradation of larger-sized plastic particles. The uptake and effects of NPs in humans is not yet known. However, recent laboratory studies have documented the uptake and adverse effects of NPs from the cellular to the community level. As NPs are in the size range of particles that can be absorbed by cells, research on these materials should be accelerated to properly assess their potential risks.

A review on microplastics and nanoplastics in the environment: Their occurrence, exposure routes, toxic studies, and potential effects on human health
This review summarizes what is known about how microplastics and nanoplastics enter the human body through food, air, and skin contact, and what they do once inside. Studies on cells and animals show these tiny particles can cause oxidative stress, DNA damage, inflammation, and harm to the immune, digestive, reproductive, and nervous systems. The research makes clear that microplastics are not just an environmental problem but a direct concern for human health.
A review on micro- and nanoplastics in humans: Implication for their translocation of barriers and potential health effects
This review compiles evidence showing that micro- and nanoplastics have been found in human blood, lungs, placenta, and other organs, and can cross protective barriers including the blood-brain and placental barriers. The accumulated evidence links these particles to inflammation, oxidative stress, hormone disruption, and potential effects on reproduction and brain health, though more research is needed to determine exact risk levels.
