Prospective Investigation of Nanoplastic Accumulation in Healthy Subjects, Autoimmune Diseases, Hematological Malignancies, Lung Cancer, and Murine Models
AI summary Read the abstract
Researchers conducted a prospective investigation into nanoplastic accumulation in human cardiac tissue, collecting heart samples and analyzing them for nanoplastic content using sensitive analytical techniques. The study provides early evidence of nanoplastic presence in cardiac tissue and raises questions about cardiovascular health implications.
Nanoplastics (NPs) and microplastics (MPs) are an emerging threat to global health. They negatively impact ecosystems and many physiological processes, causing alterations in xenobiotic metabolism, nutrient uptake, energy metabolism, or cytotoxicity. In humans, we are beginning to analyze these plastics for the mechanisms by which they enter the organism, accumulate and diffuse, and for their pathogenic potential. NP accumulation has been demonstrated in human tissues, such as blood or placenta, while in others it remains largely unstudied. In this work, we have detected NP accumulation in bronchoalveolar lavage fluids (BALF), cerebrospinal fluids (CSF), lymph nodes (LN), urine, pleural fluids (PF), ascitic fluids (AF) and peripheral blood (PB) by combining fluorescence and nanocytometry techniques. NP analysis has been compared with mouse animal models, suggesting that inhalation is the main route of NP accumulation.

A prospective investigation measured nanoplastic accumulation in blood samples from healthy subjects, patients with autoimmune diseases, and hematological cancer patients. The study found higher nanoplastic levels in patients with autoimmune and cancer diagnoses, raising questions about whether nanoplastic accumulation may contribute to or reflect these disease states.
Microplastics, Nanoplastics and Heart Contamination: The Hidden Threat
AI summary Read the abstract
This review examines growing evidence that micro- and nanoplastics can accumulate in human cardiovascular tissues, including blood, heart muscle, and arterial plaques. Researchers found that these particles may contribute to heart and blood vessel problems through inflammation, oxidative stress, blood clotting, and direct tissue injury. The study identifies plastic particles as a potential new environmental risk factor for cardiovascular health.

This review examines the cardiovascular health effects of micro- and nanoplastics, summarizing evidence that these particles have been detected in human tissues including arterial plaques and may promote endothelial dysfunction and inflammation. The authors call for further clinical and epidemiological research into cardiac risk.
Nanoplastics and Cardiovascular Health: A Review of Environmental Exposure, Biological Mechanisms and GeoHealth Implications
AI summary Read the abstract
This review paper summarizes existing research on tiny plastic particles called nanoplastics and heart health. It reports that studies have found plastic particles in human blood, lungs, placenta, blood vessels, heart tissue and arterial plaque, and lab experiments suggest possible ways these particles could affect cells, though causation has not been established.
Micro-nanoplastic induced cardiovascular disease and dysfunction: a scoping review
AI summary Read the abstract
Researchers reviewed evidence from animal and human studies on how micro- and nanoplastics (MNPs) affect the heart and blood vessels, finding that MNPs can damage the inner lining of blood vessels, promote plaque buildup, and interfere with blood clotting — all of which raise the risk of heart disease. The review calls for more research to understand how much MNP accumulation occurs in the human cardiovascular system and what it means for long-term cardiac health.
