Uncovering layer by layer the risk of nanoplastics to the environment and human health
AI summary Read the abstract
This review examines how nanoplastics, plastic particles smaller than 100 nanometers, can cross biological barriers like the gut lining and accumulate in vital organs. Once inside the body, nanoplastics can trigger inflammation, oxidative stress, genetic damage, hormone disruption, and immune problems. The authors stress the need for standardized detection methods and long-term studies to fully understand the health risks these tiny particles pose to humans.
Nanoplastics (NPs), defined as plastic particles with dimensions less than 100 nm, have emerged as a persistent environmental contaminant with potential risk to both environment and human health. Nanoplastics might translocate across biological barriers and accumulate in vital organs, leading to inflammatory responses, oxidative stress, and genotoxicity, already reported in several organisms. Disruptions to cellular functions, hormonal balance, and immune responses were also linked to NPs exposure in in vitro assays. Further, NPs have been found to adsorb other pollutants, such as persistent organic pollutants (POPs), and leach additives potentially amplifying their advere impacts, increasing the threat to organisms greater than NPs alone. However, NPs toxic effects remain largely unexplored, requiring further research to elucidate potential risks to human health, especially their accumulation, degradation, migration, interactions with the biological systems and long-term consequences of chronic exposure to these compounds. This review provides an overview of the current state-of-art regarding NPs interactions with environmental pollutants and with biological mechanisms and toxicity within cells.

Microplastics and nanoplastics in humans: exposure pathways, biological mechanisms, and implications for health risk assessment
AI summary Read the abstract
Tiny plastic particles called microplastics and nanoplastics are everywhere—in our air, food, and water—and this review pulls together existing research on how they might get into our bodies and affect our health, including triggering inflammation, disrupting gut bacteria, and interfering with hormones. The bigger takeaway is that scientists still don't have solid answers on how much exposure is actually harmful or which groups (like children or people with existing health conditions) might be most at risk. This matters because it means current safety guidelines are based on incomplete information, so more research is needed before we can say how worried we should really be.
Nanoplastics: Unveiling Contamination Routes and Toxicological Implications for Human Health
AI summary Read the abstract
This review examined how nanoplastics, the tiniest plastic particles, enter the human body through breathing, eating, drinking, and skin contact. Evidence indicates these particles may contribute to a range of health concerns across multiple body systems, including the lungs, gut, heart, brain, and immune system, highlighting the need for more research into their long-term effects.
Human Exposure to Nanoplastics and Its Toxicological and Environmental Implications
AI summary Read the abstract
Tiny plastic particles called nanoplastics are everywhere—in our water, air, and food—and this review pulls together existing research on how they get into our bodies (through eating, breathing, or even skin contact) and spread to different organs. The science suggests these particles may trigger cell damage, inflammation, hormone disruption, and other harmful effects, though researchers note it's still hard to measure exact exposure levels and long-term risks. The takeaway: nanoplastic pollution is a growing health concern worth watching, but scientists still need better tools to figure out exactly how much harm it's causing.
Human and ecological health effects of nanoplastics: May not be a tiny problem
AI summary Read the abstract
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.
Assessing toxicological risk of nanoplastics contaminants in food and feed from ingestion pathway to human diseases
AI summary Read the abstract
This review examines how nanoplastics, which are tiny fragments smaller than 0.1 micrometers, enter the human food chain and may pose health risks. Evidence indicates that nanoplastics can cross biological membranes more easily than larger microplastics, potentially reaching organs and accumulating over time. The study highlights the need for better detection methods and risk assessments to understand the long-term health implications of nanoplastic ingestion through food and beverages.
