Microplastics detected in blood clots in human body

Back to Resource Library

Researchers have detected microplastics in blood clots found in medical patients’ brains, coronary arteries, and deep veins. Plastic types found included polyvinyl chloride (PVC), polyethylene (PE), and polyamide 66 (or Nylon, commonly used to make clothing). What’s more, patients with microplastics present in their blood clots showed higher levels of D-dimer, a type of protein the body makes when blood clots form and break down.

Background: Microplastic (MP) pollution has emerged as a significant environmental concern worldwide. While extensive research has focused on their presence in marine organisms and ecosystems, their potential impact on human health, particularly on the circulatory system, remains understudied. This project aimed to identify and quantify the mass concentrations, polymer types, and physical properties of MPs in human thrombi surgically retrieved from both arterial and venous systems at three anatomically distinct sites, namely, cerebral arteries in the brain, coronary arteries in the heart, and deep veins in the lower extremities. Furthermore, this study aimed to investigate the potential association between the levels of MPs and disease severity.https://www.thelancet.com/journals/ebiom/article/PIIS2352-3964(24)00153-1/fulltext
