A recent study published by the American Heart Association has revealed the presence of micro- and nano-plastics in arterial plaque, specifically in the carotid arteries of individuals with atherosclerosis. The researchers analyzed samples from patients undergoing carotid endarterectomy, a surgical procedure to remove plaque buildup in the neck arteries. The findings show that microplastics, measuring 1-10 micrometers in diameter, and nano-plastics, measuring less than 1 micron, were present in the arterial plaque.
The presence of plastics in the body's cardiovascular system raises concerns about their potential impact on human health. While the exact mechanisms by which micro- and nano-plastics contribute to atherosclerosis are not yet fully understood, it is possible that they may trigger inflammation or other physiological responses that exacerbate plaque buildup. Further research is needed to determine the extent to which exposure to plastics contributes to cardiovascular disease.
The study's findings highlight the need for continued investigation into the effects of plastic pollution on human health and the environment. As our understanding of this issue grows, it may be necessary to reassess policies aimed at reducing plastic waste and promoting sustainability.
