Significance An 1100 BCE to 800 CE record of estimated lead emissions based on continuous, subannually resolved, and precisely dated measurements of lead pollution in deep Greenland ice and atmospheric modeling shows that European emissions closely varied with historical events, including imperial expansion, wars, and major plagues. Emissions rose coeval with Phoenician expansion and accelerated during expanded Carthaginian and Roman lead–silver mining primarily in the Iberian Peninsula…

Pervasive Arctic lead pollution suggests substantial growth in medieval silver production modulated by plague, climate, and conflict
TLDR
Results suggest substantial overall growth in lead/silver mining and smelting emissions—and so silver production—from the Early through High Middle Ages, particularly in northern Europe, with lower growth during the Late Middle Ages into the Early Modern Period.

Lead and mercury have long histories of anthropogenic use and release to the environment extending into preindustrial times. Yet, the timing, magnitude, and persistence of preindustrial emissions
Lead and Antimony in Basal Ice From Col du Dome (French Alps) Dated With Radiocarbon: A Record of Pollution During Antiquity
Lead and antimony measurements in basal ice from the Col du Dome glacier document heavy metal pollution in western Europe associated with emissions from mining and smelting operations during European
High variability between regional histories of long-term atmospheric Pb pollution
TLDR
A compilation of global records of anthropogenic atmospheric lead (Pb) spanning the last 4000 years is presented, an effective indirect proxy for reliably assessing Pb emissions directly linked to human activities.
Hemispheric black carbon increase after the 13th-century Māori arrival in New Zealand.
New Zealand was among the last habitable places on earth to be colonized by humans1. Charcoal records indicate that wildfires were rare prior to colonization and widespread following the 13th- to
Alpine Ice‐Core Evidence of a Large Increase in Vanadium and Molybdenum Pollution in Western Europe During the 20th Century
Pollutants emitted by industrial processes are deposited across the landscape. Ice core records from mid‐latitude glaciers located close to emission sources document the history of local‐to‐regional
Early atmospheric contamination on the top of the Himalayas since the onset of the European Industrial Revolution
TLDR
It is shown that an early contamination from toxic trace metals emerged at high elevation in the Himalayas at the onset of the European Industrial Revolution, and depended primarily on multidecadal changes in atmospheric circulation and secondarily on variations in emission sources during the last 200 y.
Cadmium Pollution From Zinc‐Smelters up to Fourfold Higher Than Expected in Western Europe in the 1980s as Revealed by Alpine Ice
Estimates of past emission inventories suggest that toxic heavy metal pollution in Europe was highest in the mid‐1970s for lead and in the mid‐1960s for cadmium, but these previous estimates have not

TLDR
It is demonstrated that lead emissions associated with both the historic and Old Copper Complex tradition are detectable and can be used to determine the temporal and geographic pattern of metal pollution.
Antarctic-wide array of high-resolution ice core records reveals pervasive lead pollution began in 1889 and persists today
TLDR
Detailed measurements from an extensive array of 16 ice cores quantifying substantial toxic heavy metal lead pollution at South Pole and throughout Antarctica by 1889 are shown, suggesting that this single emission source in southern Australia was responsible for the introduction of lead pollution into Antarctica at the end of the 19th century and remains a significant source today.

TLDR
Results show that heavy-metal pollution in the North Atlantic sector of the Arctic is substantially lower today than a century ago, but contamination of other sectors may be increasing because of the rapid coal-driven growth of Asian economies.
