Children's urine contains widespread microplastics, with diet potentially influencing exposure

Microplastics were found in over 91% of urine samples from 10-year-old children, with a median concentration of 250 particles per milliliter. Researchers identified 19 types of microplastics, with PTFE being the most abundant. Adherence to the Mediterranean diet was linked to different microplastic polymer profiles in the children's urine. The study suggests dietary patterns may influence microplastic exposure pathways and accumulation in children, though it cannot establish a causal relationship.
