Accumulation of Nano and Micro Plastics in Human Body

Plastics, specifically nano and micro plastics, are accumulating in the human body as evidenced by the discovery of plastic particles in artery plaques removed from patients. Researchers found a ratio of one plastic particle per 50 particles of plaque, indicating a significant accumulation. A study revealed that individuals with plastic in their blood had a four and a half times higher likelihood of experiencing heart attacks, strokes, or death. The binding of plastic fragments to dendritic cells and monocytes triggers the release of cytokines and pro-inflammatory signals, leading to heightened inflammation and potential negative health consequences. The identified plastics, primarily PET and PVC, commonly used in plastic bottles and piping, respectively, are breaking down into tiny particles that enter the food and water supply, gradually accumulating in human bodies. These findings underscore the urgent need to further study and understand the impacts of nano and micro plastic accumulation on human health.
