A new study finds children who are exposed to lead at a young age are more likely to be arrested later in life.

The study in PLoS Medicine is the first evidence that elevated blood-lead levels, both in the pregnant mother and in the child, are associated with criminal behavior in young adulthood.

Childhood lead exposure has been linked with antisocial behavior, lower IQ, ADHD and more.

In this study. arrest rates were higher as blood lead concentrations went up. Also, the association between high blood-lead levels and violent crimes was even stronger.
