Pervasive Arctic lead pollution suggests substantial growth in medieval silver production modulated by plague, climate, and conflict [Environmental Sciences]
Lead pollution in Arctic ice reflects large-scale historical changes in midlatitude industrial activities such as ancient lead/silver production and recent fossil fuel burning. Here we used measurements in a broad array of 13 accurately dated ice cores from Greenland and Severnaya Zemlya to document spatial and temporal changes in Arctic...
