Results of a 30-year study revealed that children with elevated blood lead levels before birth and during early childhood have higher rates of arrest for both violent and total crimes than the rest of the study population after age 18. Previous studies estimated lead exposure indirectly, while the current study actually determined the children’s lead levels with blood tests until they were 6 years old. Furthermore, this study followed the children into adulthood, something previous studies failed to do. Although great strides in reducing lead exposure have been made, these findings suggest that it’s still a topic of health concern. Full story.
