An evaluation of 17 previously published studies suggests that exposure to lead in the womb or in childhood is associated with an increased risk of engaging in criminal behavior in adulthood—but more evidence is needed to strengthen understanding. Maria Jose Talayero Schettino of the George Washington University, U.S., and colleagues present these findings in the open-access journal PLOS Global Public Health.
