Pollution caused by heavy metals can be traced back to the Roman Empire. In his Perspective, Nriagu considers the historical record of metal pollution and discusses results published in the same issue by Hong et al. (p. 246) in which ice core records were used to determine the quantity of copper emitted into the atmosphere by ancient smelters.
