US researchers have detected increasing concentrations of microplastics in human brain tissue. Their findings confirmed an increase in microplastic accumulation over time, with PE — the most common plastic used in packaging, bottles, and containers — as the most frequently detected polymer.Led by toxicologist Matthew Campen, PhD, professor at the University of New Mexico (UNM) College of Pharmacy, the study published in Nature Medicine found that plastic concentrations in the brain were higher than in other organs, such as the liver and kidneys.
