Regional insights into childhood lead exposure from historical North American skeletal remains
Lead (Pb) concentration and isotope analyses of human remains have been used to examine differences in Pb exposure to examine the movement of peoples and Pb-containing cultural materials. The thesis reviewed 55 bioarchaeological studies of Pb concentrations and isotope analyses of teeth and identifi...

Lead (Pb) concentration and isotope analyses of human remains have been used to examine differences in Pb exposure to examine the movement of peoples and Pb-containing cultural materials. The thesis reviewed 55 bioarchaeological studies of Pb concentrations and isotope analyses of teeth and identified limitations in the archaeological, ethnographic, and historical documentation, and variability in tooth choice and analytical approach that complicate transparency and interpretation. Early fishing settlements (17ᵗʰ to 19ᵗʰ century) in Newfoundland and Nova Scotia lacked local anthropogenic Pb exposure. Pb concentrations in tooth enamel of 46 individuals from St. Paul’s Anglican Church (Harbour Grace), Foxtrap-2 (Foxtrap), Wester Point (Portugal Cove-St. Philip’s), Tors Cove, St. Luke’s Anglican Church (Placentia), and Block-3 (Louisbourg) cemeteries ranged from 0.1 to 28.9 ppm.
