Zinc elemental maps were taken on the enamel of an archaeological tooth to determine if zinc was affected by the post-mortem environment. Zinc is an important dietary trace element and deficiency is common in malnutrition and chronic illness. A permanent premolar from an Australian child who died in the second half of the 19th century was compared with contemporary premolar. Teeth were cut in the mid sagittal plane and were analysed using the Australian Nuclear Science and Technology Organisation (ANSTO) High Energy Heavy Ion Microprobe. Maps were produced showing the distribution of zinc across the enamel as well as linear profiles from the outside enamel to inside enamel. Results show the distribution of zinc in the archaeological tooth is quite different to the contemporary tooth, raising the suggestion that zinc has been significantly altered by the post mortem environment.
