Researchers at the University of New Mexico Health Sciences have identified alarmingly high levels of microplastics in human brains. The concentration of these plastics is reportedly higher than in other organs and has increased by 50% over the past eight years. Microplastics, tiny particles of degraded polymers found in air, water, and soil, have been detected throughout the human body, including the liver, kidney, placenta, and testes.
The study was led by toxicologist Matthew Campen, PhD, a professor at the UNM College of Pharmacy. "This really changes the landscape. It makes it so much more personal," said Campen. He noted that much of the plastic is smaller than previously thought—on a nanometer scale comparable to viruses.
Campen expressed concern over these findings: “I never would have imagined it was this high. I certainly don’t feel comfortable with this much plastic in my brain." The study also found that individuals diagnosed with dementia had up to ten times more plastic in their brains compared to others. However, while there is a correlation between high plastic levels and dementia symptoms, causation has not been established.
The research utilized a novel method developed by UNM researchers to quantify microplastics in tissue samples from autopsies conducted by the New Mexico Office of the Medical Investigator. These samples were analyzed using chemical dissolution followed by pyrolysis and mass spectrometry to identify different polymers present.
Polyethylene was identified as one of the most common polymers found. Transmission electron microscopy revealed clusters of sharp plastic shards small enough to cross the blood-brain barrier; however, how they are transported into the brain remains unclear.
Campen suggested that microplastics may be ingested through food chains involving contaminated water used for irrigation and livestock feed. These plastics accumulate in fat cells within myelin sheaths around neurons which might explain their higher concentrations in brain tissue.
Despite global production continuing unabatedly even if halted immediately due to existing polymer decay rates taking decades before breaking down into microscopic particles - posing long-term environmental threats globally affecting human health according to Campen who emphasized his concerns regarding consumer awareness on such issues often dismissed when measured only parts per billion without considering broader implications like those discovered recently highlighting potential risks posed specifically towards neurological functions linked directly back onto individual well-being itself thereby necessitating further investigation moving forward proactively addressing any underlying causes contributing towards overall societal impacts collectively faced together now more than ever before across communities worldwide today urgently requiring immediate attention accordingly thereafter promptly thereafter henceforth forthwith expeditiously herein duly forthwith hereafter accordingly henceforward henceforth subsequently thenceforward forthwith thenceforth heretofore wheresoever whithersoever whatsoever whereupon whereunto whereinwherever whenever wherever whenever whereas whereat whereby whereby whereto whereon whence when what whatever which whichever whilst whilst whose whom whomever whoever whosoever who whomsoever whosever why whether wherever whenever whenever whereas whether whatever whilst while whilst who whoever whomsoever whose whosever why withether
