Medieval teeth reveal early lead poisoning in England’s Peak District
Researchers used tooth enamel from 650‑1500 CE graves to date the rise of lead mining in the Peak District.

Archaeologists have dated the start of widespread lead exposure in medieval England by analysing dental enamel from graves in the Derbyshire Peak District, the team reported in a study published in Antiquity on 12 Oct 2026.
What happened
The researchers examined teeth from three cemeteries in the central England region, with burials ranging from 650 to 1500 CE. Because enamel forms in childhood and retains trace elements for life, the samples provide a chronological record of lead intake. The analysis showed that by the mid‑7th century, children in Derbyshire had lead levels comparable to, or higher than, those recorded in industrial‑era cities of the 18th and 19th centuries. Exposure peaked in the late 12th and early 13th centuries, coinciding with historical evidence of expanding lead smelting operations.
What the reports add
The article notes that lead mining in the region dates back to the 7th century, after a post‑Roman lull, and that the Peak District became one of Europe’s largest medieval lead producers. It also highlights that the metal’s distribution was uneven: high‑status graves contained personal items such as weapons, suggesting socioeconomic differences in exposure.
What was said
University of Nottingham archaeologist Christopher Loveluck said, “The team is delighted to have finally confirmed definitively the date by which the early medieval lead industry was established in the Peak District…through evidence provided by the people themselves.” The quote is attributed to the study’s announcement as reported by Popular Science.
How it came about
Lead has been used by humans for over 9,000 years, with archaeological traces extending two million years. While the metal drove technological advances, its toxicity is now well documented. The new research builds on earlier work that traced lead’s environmental legacy through smelting waste re‑processed from Roman and medieval sources, a practice that previously obscured the metal’s early distribution patterns.
