“Truth Fairies” Find Poison in the Mouths of Babes

Baby teeth collected in 5 Los Angeles neighborhoods showed high amounts of lead traced to recycled car batteries at a nearby Exide plant—shuttered for hazardous waste violations in 2015.
University of Southern California researchers examined the teeth by layer and assigned lead contamination times beginning with the second trimester of pregnancy. Their “Truth Fairy” study, in Environmental Science & Technology, highlights the need to test women for lead during pregnancy or earlier.
“There’s no safe level of lead; it’s a potent neurotoxin. Our study provides insight into the legacy of the impact of industrial contamination on children,” says lead author Jill Johnston of USC’s Keck School of Medicine.
