ClearWeathered microplastics in human blood: unraveling the effect of structural changes at the particle surface on coagulation and platelet activation
Researchers exposed human whole blood to microplastics that had been artificially aged to simulate real environmental weathering, finding that weathered plastics like polystyrene, PVC, and PET triggered significantly stronger blood clotting and platelet activation than fresh plastic particles. The findings suggest that the longer plastic sits in the environment and degrades, the more dangerous it may become to human cardiovascular health.

The study highlights the need for more research on how chronic exposure to these tiny plastic particles may contribute to cardiovascular health risks.
PB1065 Microvesicles Display Opposite Coagulolytic Balances According to Their Cellular Origin and Activation Status
Polystyrene microplastics activated human vascular endothelial cells, upregulating inflammation markers ICAM-1 and VCAM-1, and promoted larger and denser blood clot formation when added to whole blood perfused over collagen at concentrations found in human plasma. These results raise concern that microplastics circulating in human blood could increase the risk of thrombosis and cardiovascular events.
Micro- and nanoplastics: A new cardiovascular risk factor?
This review examines the growing evidence that micro- and nanoplastics may pose risks to the heart and blood vessels. Studies in animals and cell cultures show that these tiny plastic particles can enter the bloodstream, trigger inflammation, promote blood clotting, and damage blood vessel walls. While human data is still limited, the review suggests that micro- and nanoplastic exposure should be considered a potential new risk factor for cardiovascular disease.
Multimodal detection and analysis of microplastics in human thrombi from multiple anatomically distinct sites
This study used multiple detection methods to find and analyze microplastics in blood clots (thrombi) collected from different locations in the human body. The detection of microplastics within blood clots from various anatomical sites suggests that plastic particles may play a role in clot formation. This research adds to mounting evidence linking microplastic presence in the cardiovascular system to potential heart and stroke risks.
Microplastic particles in human blood and their association with coagulation markers
In a study of 36 healthy adults, microplastics were detected in the blood of 89% of participants, with polypropylene and polyethylene being the most common types found. Higher microplastic levels were associated with changes in blood clotting markers, suggesting that plastic particles in our bloodstream may affect how our blood coagulates, though larger studies are needed to confirm this link.
Evidence, Mechanisms, and Clinical Implications of Microplastics and Nanoplastics As Emerging Cardiovascular Risk Factors: A Narrative Review
This review examines growing evidence that micro- and nanoplastics may contribute to cardiovascular health risks, with researchers having found these particles in human artery plaques and blood clots. Evidence indicates that the particles can enter the bloodstream, trigger inflammation, damage blood vessel walls, and potentially increase the risk of heart attacks and strokes. While the evidence is not yet conclusive, the study highlights an emerging area of concern that warrants further investigation into how everyday plastic exposure may affect heart and blood vessel health.
Emerging cardiovascular risks of micro- and nanoplastics: toxic effects and mechanistic pathways
Tiny plastic particles called micro- and nanoplastics are getting into our bodies through food, air, and skin contact, and researchers have found them building up in people's hearts and blood vessels. This review of existing studies shows these plastic bits may contribute to heart disease by causing inflammation and damaging cells in the cardiovascular system. While more research is needed, this suggests that plastic pollution isn't just an environmental problem—it could be directly harming our heart health.
Effects of micro- and nanoplastics on blood cells in vitro and cardiovascular parameters in vivo, considering their presence in the human bloodstream and potential impact on blood pressure
This review examines evidence that micro- and nanoplastics can enter the human bloodstream and interact with blood cells, with plastic particles already detected in human blood, blood clots, and artery plaques. While direct evidence linking microplastics to blood pressure changes in humans is still lacking, animal studies and the mechanisms identified -- including blood vessel damage and inflammation -- suggest cardiovascular effects are plausible.
Microfluidic-based in vitro thrombosis model for studying microplastics toxicity
Researchers developed a microfluidic-based thrombosis model to study how microplastics interact with the vascular system. Using both a mouse model and an on-chip system, the study found that microplastic exposure led to accumulation in the blood and decreased binding of fibrin to platelets, suggesting a potential risk of thrombus instability in blood flow.
Kinetics and toxicity of nanoplastics in ex vivo exposed human whole blood as a model to understand their impact on human health
Researchers exposed human whole blood to five types of nanoplastics and found that immune cells, especially monocytes, readily absorbed the particles, triggering oxidative stress and inflammatory responses. Different plastic types caused different effects: some triggered blood clotting, others caused red blood cell damage, and PLA (a "biodegradable" plastic) was among the most reactive. This study provides direct evidence that nanoplastics reaching the human bloodstream can disrupt immune cells, blood clotting, and inflammation.
Polystyrene nanoplastics enhance thrombosis through adsorption of plasma proteins
Researchers found that polystyrene nanoplastics can enter the bloodstream and increase the risk of blood clots by adsorbing key clotting proteins, particularly coagulation factor XII and plasminogen activator inhibitor-1. This protein-adsorption mechanism was confirmed through multiple analytical approaches. The discovery of this thrombosis-promoting pathway is concerning because it suggests that nanoplastic exposure could increase cardiovascular risks like stroke and heart attack.
