#AI Reads Urine# Impact of urinary microplastic exposure on cognitive function in primary school children

This cross-sectional study conducted in Shenyang, China, involving 5,670 primary school children aged 7 to 10, measured urinary levels of polyamide, polypropylene, and polyvinyl chloride microplastics and evaluated their cognitive functions—including working memory and attention—through computerized tasks. The results showed that higher urinary concentrations of polyamide, polypropylene, and total microplastics were significantly associated with reduced working memory and superior working memory performance in children. Total microplastic exposure was also linked to increased reaction time variability, indicating inattentiveness. Multiple statistical models supported a dose-dependent negative association between urinary microplastic exposure and cognitive development, providing important evidence that microplastic exposure may impair cognitive function in children.
