Re: Lead Dangers

At a tour of St.John's Mine in Wisconsin, the owner/guide stated that Galena was not as dangerous as you would think as it is not pure lead or lead oxide, but a mineral composed of lead and sulphur that is not very soluble . I believe he said there was no record of any galena miners falling ill to lead poisoning, however the workers that burned the sulphur off to make lead did often get sick. I don't have any reason to doubt the gentleman as this has the ring of truth to it. It seems that galena deposits underground are extrememly stable materials little affected over time by water and oxygen. Anyone able to back up the insolubility claim?
