Lead pollution linked to lower IQs in Roman Empire

Roman Empire's Air Pollution May Have Lowered The IQ of Europe
Using modern evidence of lead pollution and its health effects, the international team calculates that lead exposure in the Roman golden age could have caused a population-wide drop in IQ of about 2.5 to 3 points per person. And that goes for most of the Roman Empire, including its provinces of Gaul, northwestern Africa, Iberia, and Britannia.
