POLLUTERS IN TOGAS
New findings from France indicate that humans were first-class polluters well before the Industrial Revolution. As early as 2,500 years ago, in fact, Greek and Roman smelters spewed enough lead to contaminate the entire northern hemisphere, according to a study by France's Domaine University that analyzed lead preserved deep in Greenland's ice. The oldest-ever toxic fallout, long suspected by other scientists, began with pollution from Central European silver refining and other post-Bronze Age industry, and lasted 800 years. With 400 tons of lead found in Greenland alone, the damage rivals that of the 20th century's main culprit: leaded gasoline.
