It came from deep within the ground, in the form of lead ore,

In Europe, there are places where the Romans smelted lead 2000
years ago, and 8" or so below the topsoil, the dirt is still so
toxic that health officials (in Britain at least) don't allow
people to dig there, even wearing protective gear.


The slag they skimmed of wile refining the lead is what is toxic, not
the lead. Those compounds already existed. They were just mixed up in
the ore.
