Pb released 22 years prior raises the present period aggravated assault rate by 0.

For every metric ton of Pb released 22 years prior, a latent increase of 1. Vehicles consuming fuel containing Pb additives contributed much larger quantities of Pb dust than generally recognized. Our findings along with others predict that prevention of children’s lead exposure from lead dust now will realize numerous societal benefits two decades into the future, including lower rates of aggravated assault. Chicago, Indianapolis, Minneapolis, San Diego, Atlanta and New Orleans were studied. Pb increase 22 years prior raised aggravated assault by 0. Childhood Pb prevention may yield numerous benefits in two decades, including less violence.
