Medieval lead mining pollution found in ice cores

Researchers found proof of lead production increases and decreases in Alpine ice cores.
The BBC has a story here and a link to the article in Antiquity

So be careful with any miasmas created by your industrial production!


I believe it - in Why Nations Fail, they pointed out that you can see lead pollution via ice core samples peak and then decrease throughout the Roman Empire's rise and fall. I believe the Ice Cores were from Greenland.

Yeah, there's not much else than lead mining/smelting that would produce measurable lead levels in ice cores.

Note that Mythic Locations has one of its featured sites as a Roman lead mining operation.
