Abstract

This research was mainly focused on performing analysis of arsenic in stream sediments, soils and rocks in an area at the confluence of Piranhas and Seridó Rivers in Rio Grande do Norte state, northeast of Brazil. The methodology of collecting and preparing samples for analysis followed international standards of quality (QA / QC) and was carried out in conjunction with the Canadian Company Eldorado Gold Corp., through its Brazilian subsidiaries. Arsenic is present in concentrations above reference values in an area that is located upstream of the Oiticica Dam, which is under construction and has a storage capacity of 556 x 106/m³, and will supply a large portion of the population from the State semiarid region where live more than one hundred thousand people, considering only municipalities directly affected.
