The article discusses the troubling trend of microplastics being discovered in various human organs, with a notable concentration found in brain samples. A study highlighted the dramatic rise of microplastics in cadaver brains over eight years, revealing concentrations up to thirty times higher than in the liver or kidneys. Notably, this study reinforces that our bodies may eliminate nanoplastics over time, but the health implications of microplastics' accumulation, particularly in the brain, remain unclear, urging further investigation into this critical issue.
The blood distributes it, but as happens with the tides, there are shores where more waste accumulates than others. And there is one that stands out for its large accumulation of microplastics: our brain.
Concentrations were seven to 30 times higher in brain samples than the concentrations observed in the liver or kidney, emphasizing a shocking disparity.
The possible implications for human health of this disturbing finding are still unclear, highlighting a significant knowledge gap regarding the biological effects of microplastics.
Matthew J. Campbell emphasized that our increasing exposure to plastic is the reason for heightened microplastic concentrations in brain tissue over the past few years.
