Silvering vs. Tinning
#7
Quite so- our modern 'fear' of lead is, like many things, a little overblown- sure it's not nice stuff, but tiny amounts aren't going to kill you, and may only affect you over long periods of exposure time.

Acids are the main culprit for getting lead into food and drink- the members of the Franklin Expidition to map the Northwest Passage in Canada's nort, for example, are thought to have suffered from significant poisoning as a result of contaminated acidic canned foods- the acid acting on the lead solder that sealed the cans. Of course this was over a period of years with the men eating only the canned food and perhaps occasionally seal meat. And the lead poisoning didn't kill them- disease, exposure, and starvation did- it is just suggested to have seriously affected their mental processes such that they made questionable decisions and were ultimately all lost.
