Baby teeth reveal how early exposure to metals alters brain development in adolescence

According to scientific research published in the journal Science Advances, environmental exposure to various metals during gestation and the first months of life can alter brain development and increase certain health probabilities during adolescence. The study's findings were discovered through the analysis of baby teeth, which serve as biomarkers for early-life metal exposure.

This research establishes a direct biological link between early developmental exposure to environmental elements and subsequent neurological impacts later in youth. The findings highlight the critical vulnerability of infants and fetuses to toxic metal exposure and provide new methods for tracking these developmental risks using primary biological indicators.
