This academic paper traces the history of human lead use from the Neolithic period through modern times, exploring how smelting, leaded fuel, water pipes, and paint contributed to widespread environmental and health contamination. Using lead isotope signatures found in Greenland ice cores, researchers identified a 200-fold increase in atmospheric lead levels between 800 BCE and the 1960s, with the sharpest rise after 1940. The study also examines the measurable impact of lead exposure on human health through analysis of ancient and modern skeletal remains.Open full document
Notes
This paper explores the history of lead use from the Neolithic period through modern times, examining how ice core studies from Greenland revealed a 200-fold increase in atmospheric lead contamination from 800 BCE to the 1960s. Lead isotope signatures are used to trace sources of environmental contamination, including industrial smelting and leaded gasoline. The paper also examines the human health impacts of lead exposure as evidenced by archaeological and modern skeletal lead levels.
