From food-to-human microplastics and nanoplastics exposure and health effects: A review on food, animal and human monitoring data
AI summary Read the abstract
This review summarizes existing research on how microplastics and nanoplastics move from food into animal and human tissues, and what health effects they may cause. Studies show these particles have been found accumulating in organs including the liver, lungs, placenta, and blood, with their size and chemical properties determining where they end up in the body. The authors stress the need for standardized testing methods and human biomonitoring to better understand the real health burden of microplastics in our food supply.
This review figures out the overall status on the presence of microplastics (MPs) and nanoplastics (NPs) in food and their bioaccumulation in animal and human tissues, providing critical insights into possible human health impacts. Data are discussed on both in-vivo and ex-vivo animal and human studies, and the role of physicochemical properties in determining the biological fate and toxicological effects of MPs and NPs. Particular attention is given to dietary exposure assessments, specifically evaluating daily intake through the consumption of contaminated food items. The current limitations in the body of knowledge and some considerations for future assessments are also reported. Overall, there is a pressing need to establish more robust biomarker research and develop standardized methodologies, for a better understanding of MPs and NPs fate and associated effects in more realistic scenarios for their safe consumption. The review underscores the importance of integrating the human biomonitoring into monitoring programs and interdisciplinary research to ultimately inform on MPs and NPs real burden in the human body.

Nano- and microplastics: a comprehensive review on their exposure routes, translocation, and fate in humans
AI summary Read the abstract
This comprehensive review traces the journey of nano- and microplastics through the human body, covering how they enter through breathing, eating, drinking, and skin contact. Once inside, the smallest particles can cross the gut and lung barriers, enter the bloodstream, and accumulate in organs including the liver, kidneys, and placenta. The review highlights significant knowledge gaps about long-term health effects but notes that the evidence for internal accumulation in humans is growing.
