A closer look at “Children with Autism Show Higher Levels of 19 Toxic Chemicals in Teeth, Study Finds”, exactly as the source publishes it. A new study reveals that children with autism have significantly higher levels of 19 potentially toxic chemicals in their baby teeth compared to neurotypical children. Researchers analyzed deciduous teeth from children in Denmark and found elevated concentrations of metals like lead, zinc, and manganese, as well as other environmental toxins. The findings, published in a peer-reviewed journal, suggest that early-life exposure to these chemicals may play a role in autism development.
The study used tooth matrix biomarkers to measure prenatal and early postnatal exposure, offering a unique window into fetal and infant chemical burden. While the results do not prove causation, they add to growing evidence linking environmental toxins to neurodevelopmental disorders. Experts caution that autism is complex and likely involves genetic and environmental factors. The full version stays on the original page, which this listing opens directly.
