Lead pollution in ancient Rome likely dropped the average IQ, a study found. The research is based on an analysis of ice cores extracted from Greenland.

Ancient Romans' IQ was reduced by the lead in the air they breathed, a new study says. The thirst for silver needed to mint sesterces had deleterious consequences for the health of the citizens of the Roman Empire,

Silver fueled the rise of the Roman Empire. But the ancient process of mining and extracting silver was also making the air thick with lead, scientists found.

In today’s health headlines, what we learn about lead poisoning from ancient Rome. Also, putting the first bird flu death into perspective and the Food and Drug Administration is taking a closer look at making pulse oximeters effective for all skin tones.

Using Arctic ice core samples, researchers estimate silver mining and smelting released enough lead during the Pax Romana to cause a 2.5- to 3-point drop in IQ

The new research adds context to a long-standing debate about the role lead pollution and poisoning may have played in the collapse of the Roman Empire. Some historians have argued that Roman elites and emperors who purportedly displayed odd,

Lead exposure is responsible for a range of human health impacts, with even relatively low levels impacting the cognitive development of children. DRI scientists have previously used atmospheric pollution records preserved in Arctic ice cores to identify periods of lead pollution throughout the Roman Empire,

The mass production of silver coins in the Roman Empire had an unintended effect: spewing so much lead into the atmosphere that it may have lowered citizens’ IQs.
