Abstract

The objective of this work was to evaluate the mobility of Al, Fe, Mn, Ti, and organic matter in the sediments of the area called Volta Grande do Xingu, the site is influenced by the Belo Monte Hydroelectric Complex, municipality of Altamira-Pará, region of Brazilian Amazon. In relation to the total content of elements found in the sediments, the order of abundance obtained, based on the average found in the analyzed points, was: Al (20560 mg.kg-1 ) > Fe (16148 mg.kg1 ) > Ti (5534 mg.kg-1 ) > Mn (273 mg.kg-1 ). As for the distribution of elements in the geochemical environment, the mobility order found was: Mn (50.8%) > Fe (1.53%) > Al (0.60%) > Ti (0.00%). The organic matter contents ranged from 0.73 to 19.73%, with an average value of 4.95±4.48%. The data obtained revealed a high association between FeMn-Ti, mainly attributed to the lithology of the region.
