Archaeologists find lead industry origins in Derbyshire teeth
Researchers led by the University of Nottingham used ancient teeth to date Britain's largest medieval lead industry in the Derbyshire Peak District.
Roman mining ended centuries ago
Centuries of re-smelting industrial waste erased most physical traces of early production sites. The team turned to human teeth because tooth enamel preserves a permanent chemical record of childhood pollution exposure. This biological archive allowed scientists to see when mining restarted after the fall of Roman Britain.
Industry began in seventh century
Analysis of lead concentrations revealed that smelting operations resumed during the mid-seventh century. The research was published in the journal Antiquity by a group including the British Geological Survey and the University of Sheffield. These findings show how the industry shaped local community lives long before modern environmental concerns.
