Seventh‑Century Lead Pollution Revealed

Tooth‑enamel chemistry from Derbyshire cemeteries shows children were heavily exposed to lead by the mid‑700s, implying local lead production and home pollution resumed centuries after Rome. The study uses enamel (which locks childhood exposure) and reports widespread values far above natural background, rivaling industrial urban levels of the early modern period. — Revises the historical timeline of industrial pollution and highlights enduring environmental and public‑health legacies that inform debates about remediation, heritage, and how we detect hidden industrial activity.
