Nature: Excavations of a peat bog near Dijon, France have given researchers a look at
the environmental history of a Celtic mining town.
Experts working on a peat bog near Dijon, France, are learning a valuable
lesson about human impact on the environment. Even though the land around the
site is totally green, archaeologists have found a long history of pollution
dating from before the first century and continuing through the eighteenth.
"This demonstrates that any lead pollution we create today will persist for
thousands of years into the future," says Fabrice Monna from the University of
Bourgogne in Dijon, leader of the excavation.
The team believes that the site was used for mining as early as 1300 BCE, but
that activity increased to its peak when a Celtic tribe occupied the site in
the first century. Rich deposits of lead, silver and zinc were discovered in
the area, and most trees were cut down for use in the smelting operation.
