A recent study reveals a concerning rise in microplastic contamination in human brain tissues over the last 50 years, alongside findings in other organs such as the liver and kidneys. Analyzing postmortem samples, researchers found microplastic levels significantly elevated in individuals with dementia, though causality remains unclear. While microplastics are prevalent in various human bodily fluids, their long-term health implications are largely unknown and linked to serious health issues like strokes. There’s an urgent need for further research to understand the potential connections between microplastic exposure and neurological disorders.
The exponential rise in microplastic pollution over the past 50 years may reflect increasing contamination in human brains according to a new study.
The scientists found that the concentration of microplastics was about six times higher in brain samples from people who had dementia.
Given the exponentially rising environmental presence of micro- and nanoplastics, this data compels a much larger effort to understand whether they have a role in neurological disorders.
Microplastics have been found in blood, semen, breast milk, placentas, and bone marrow, but the overall impact on human health is largely unknown.
