Lead burden in prehistorical, historical and modern human bones
G. Drasch
From archaeological findings it is well known that, in the past, lead has been intensively used by man. The toxicological aspects of increased exposure are perceived onward from 2nd century B.C.; between 90 and 95% absorbed stored bone. Therefore measurement levels ancient bones seemed to be a suitable approach determine real body burdens at different periods time compare results with present situation. Approximately 650 total 332 individuals following epochs were analysed: prehistorical Peruvians, Teutons, late Romans, Middle Age (further differentiated), Germans. determination was made graphite furnace atomic absorption spectroscopy. possibilities postmortem alterations concentrations thoroughly investigated. For this purpose dependence found compared age, sex, type bone, conditions preservation storage. It concluded that only series “prehistorical Teutons” may exposed which relevant changes. concentration group Peruvians” can taken as “physiological zero point”; culture no use known. burden for Germany about 20 times greater than point”. In Roman epoch, but also 41–47% today. Only after Barbarian Invasions did value drop 13% result lower living standard. sources during times, today discussed.
