How about this?
Crime Reduction Linked To Lead-Free Gasoline

from the getting-the-lead-out dept.
Hugh Pickens writes "Even low levels of lead can cause brain damage,
increasing the likelihood of behavioral and cognitive traits such as
impulsivity, aggressiveness, and low IQ that are strongly linked with
criminal behavior. The NYTimes has a story on how the phasing out of
leaded gasoline starting with the Clean Air Act in 1973 may have led to
a 56% drop in violent crime in the US in the 1990s. An economics
professor at Amherst College, Jessica Wolpaw Reyes, discovered the
connection and wrote a paper comparing the reduction of lead from
gasoline between states (PDF) and the reduction of violent crime. She
constructed a table linking crime rates in every state to childhood lead
exposure in that state 20 or 30 years earlier. If lead poisoning is a
factor in the development of criminal behavior, then countries that
didn't switch to unleaded fuel until the 1980s, like Britain and
Australia, should soon see a dip in crime as the last lead-damaged
children outgrow their most violent years."
