Roman Empire, lead

Roman Empire’s lead pollution was high enough to lower IQs, study says
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.
Widespread lead pollution in the Roman era made led to a drop in IQ across Europe, study suggests
"A 2 to 3 points lower IQ doesn't sound like much, but when you apply that to the entire European population, it's quite a lot."
Ancient lead pollution may have lowered IQs across the Roman Empire
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,
Roman-Era Lead Pollution Linked to IQ Drop Across Europe
DRI scientists analyzed Arctic ice core records to reconstruct historical atmospheric lead pollution from Ancient Rome, uncovering a link between lead exposure and cognitive decline. Lead exposure is a significant public health concern,
Scientists studying Arctic ice unlock link between lead pollution and lower IQs in ancient Rome
Researchers measured lead pollution and its impact on human health through Arctic ice-core samples. View on euronews
Lead pollution in ancient Rome may have dropped average IQ by up to 3 points, study finds
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.
Lead pollution linked to lower IQs in Roman Empire: Study
Atmospheric lead pollution likely caused cognitive decline among citizens of the Roman Empire, according to research published Monday in the Proceedings of the National Academy of Sciences. Researchers analyzed ice core records for an approximately thousand-year period corresponding roughly with the period from the Roman Republic through the decline of the empire,
Lead Pollution Was Likely Widespread in the Roman Empire
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 pollu
Lead pollution likely caused widespread IQ declines in ancient Rome
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,
Lead Pollution Linked to IQ Decline in Roman-Era Europe
A study analyzing Arctic ice cores reveals that lead pollution during the Roman Empire's height contributed to an estimated 2-3 point IQ decline across Europe.
Lead Pollution May Have Lowered IQs in Ancient Rome, Study Finds
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.
How Pollution in Ancient Rome Lowered IQ of Population
Lead pollution might sound like a modern problem, but people were subjected to significant levels during antiquity, too.
