Summary

This study tests if teaching children and parents about avoiding certain chemicals (like BPA) can actually lower the levels found in kids' urine. About 700 children aged 6 to 8 in Belgium and Spain will take part in a school program over two and a half years. The goal is to see if this approach can reduce chemical exposure and potentially prevent health problems such as early puberty.
