Abstract

The object of this work is the Araras archaeological site, located in Pará State, municipality of Maraba / PA. Archaeology is an interdisciplinary science requires contributions from other sciences to be able to contribute to the study of prehistoric societies, considering how tiny is the quantity and quality of the materials produced by these people. The health study of pre-Columbian populations is still quite restricted to findings of bones and coprolites, so this work is to provide another means of studying the health of these people, through analysis of trace elements. The objective of this work is to conduct chemical analysis multi element in soil samples, prehistoric pottery and water from the site Araras, pointing to possible diseases in the affected population that lived in this area around 400-500 AP. For the field study, we performed a multistage methodology advocated by Redman (1975). In laboratory tests, we used the Methodology multi acidic by ICP to obtain the amount of the trace elements, Fe, Cu, Zn, Se, Mo, Co, Cr and Mg concentration was found to evaluate and make parallel with dietary intakes of recommended allowance (RDA) for each element.
