    Lead, isotopes and ice: a deadly legacy revealed

    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.
