"The mental health burden of America's largest public-works environmental disaster clearly continues for many adults in Flint," says Aaron Reuben.

Black children with a history of lead exposure have lower test scores than their peers, and segregation exacerbates this effect, research finds.

As of 2015, more than 170 million Americans had clinically concerning levels of lead in their blood when they were children, likely resulting in lower IQs.

Children exposed to lead in drinking water from private wells may be at increased risk for delinquency as teenagers, a new study shows.

People who grew up with higher levels of lead exposure had lower levels of conscientiousness and agreeableness and higher levels of neuroticism as adults.

Decades after federal bans ended widespread use of lead paint and gasoline, some urban soils still contain levels that exceed safety guidelines for kids.

Research in Puerto Rico indicates how exposure to toxic metals can disrupt pregnancy hormones. That disruption can cause preterm birth and low birth weight.

"...there are deficits and differences in the overall structure of the brain that are apparent decades after [lead exposure]."

A more precise screening index could monitor chronic lead exposure, say researchers. They started with Atlanta, but say the approach could work elsewhere.

New research uncovers lead compounds in red and black inks on ancient Egyptian papyrus. Here's why that's notable.
