Microplastics in human body: a narrative on routes of exposure to contamination and potential health effects
AI summary Read the abstract
Tiny plastic particles from our environment and food are getting into our bodies through eating, drinking, and breathing, and this review of existing research shows they've been found in organs like the liver, heart, and lungs. Scientists are concerned that as these particles build up over time, they may cause cell damage, inflammation, and stress on the body, though more research is still needed to fully understand the long-term health risks. The takeaway: microplastic exposure is nearly impossible to avoid completely, but reducing contact with plastic packaging and products may help limit how much ends up in your body.
Microplastics (MPs) pollution has emerged as a significant global environmental concern, with these particles being detected across diverse ecosystems and infiltrating the food chain, raising concerns about their potential impact on human health. In recent years, studies have increasingly focused on understanding the possible harmful effects of MPs exposure on the human body. This review seeks to offer a detailed examination of the main pathways through which humans are exposed to MPs pollution. MPs, upon entering the human body, have been shown to move through various tissues and organs. Studies show that they can reach the liver, heart, lungs, and some other organs. Researchers have detected MPs in human feces and demonstrating that MPs ingested or inhaled can build up within the body, possibly triggering immune responses and localized toxicity. Prolonged exposure to MPs could lead to their accumulation, potentially causing DNA damage, oxidative stress, and inflammatory reactions.

AI summary Read the abstract
Researchers reviewed the human health risks of microplastic exposure across multiple organ systems, finding evidence that these particles trigger oxidative stress, disrupt gut microbiota, impair liver and cardiovascular function, suppress immunity, and — through leached additives like phthalates — act as endocrine disruptors with synergistic effects when combined with co-occurring environmental pollutants.

Human Microplastics Exposure and Potential Health Risks to Target Organs by Different Routes: A Review
AI summary Read the abstract
A review estimated that adults ingest hundreds of thousands of microplastics annually via food, drinking water, and especially inhalation — the dominant exposure route — with particles accumulating in multiple organs and inducing oxidative stress, genotoxicity, reproductive toxicity, and inflammation. The comprehensive exposure and organ-level impact data provide a clearer picture of the human health burden from ubiquitous microplastic contamination across all daily exposure pathways.
