> A similar effect has happened in former battle grounds, leaving the locals exposed to all of the known consequences of early life lead exposure including (ironically) an increased propensity for violence. Has there been a study showing this correlation? As far as I know, countries that were shattered in World War 2, like Japan and Germany, are less violent on average, than the US. And note: the mainland continental US has been relatively at peace, and has not had any major domestic hostilities since 1865. Also, have bullets always (historically) had lead? Or is this something that only newer ammo (since WWII) have?

The major source for environmental lead during the second half of the 20th century has been gasoline, not ammunition, and the correlation is quite well established: https://en.wikipedia.org/wiki/Lead%E2%80%93crime_hypothesis https://en.wikipedia.org/wiki/Lead%E2%80%93crime_hypothesis

> As far as I know, countries that were shattered in World War 2, like Japan and Germany, are less violent on average Mainland Japan did not see any ground fighting, only firebombing and the two atomic bombs. Therefore, one would not expect the locals to have been exposed to the results of infantry firing thousands and thousands of bullets.

  And most of the fighting in WW2 took place way outside German soil. By the time the frontline reached Germany, the war was almost over.

  Depends on how you define bullet - sling ones had lead as a better but more expensive option. Some really early ones used stones or wooden bolts but firearms hadn't really taken off then and they fell into obscurity for a reason. Before they also had more common /even worse/ practices like casting bullets by campfire for better fit and logistics than early manufacturing.

Parts of France are still uninhabitable due to pollution from munitions in WWI.

  The use of poison gas probably has more to do with that. Even in inhabited parts of France they have an “iron harvest” as plows continue to turn up unexploded ordinance.
