Rising Levels of Plastic Particles Found in Brain: New Study Reveals Alarming Trend

A new medical study conducted by the University of New Mexico has revealed a significant increase in the presence of tiny plastic particles in the human brain over the last 50 years. The study, which analyzed post-mortem samples from individuals who passed away between 1997 and 2024, discovered that the concentration of these plastic particles is steadily rising in the brain, liver, and kidneys.

The findings raise concerns about the impact of plastic pollution on human health, although the precise effects of these particles on the brain remain unclear. Previous studies have linked microplastics to various health issues, including stroke and heart attacks. The study also found that individuals with dementia had six times more plastic particles in their brain compared to healthy individuals, although researchers believe this may be due to brain damage caused by dementia rather than a direct connection.

In addition to the brain, the study found traces of plastic in other body parts, including blood, breast milk, and bone marrow. The most common plastic particles detected were polyethylene, often used in plastic bags and food packaging. The research indicates a gradual increase in plastic contamination from 1997 to 2024, with the highest levels found in samples from individuals who passed away in 2024.

While the study provides important insights into the growing problem of plastic pollution, researchers caution that more investigation is needed before drawing definitive conclusions about its long-term effects on health. The findings were published in the *Nature Medicine* journal.
