The objective of this study was to evaluate the concentration of toxic metals Lead (Pb), Zinc (Zi), Nickel (Ni), Copper (Cu), and Cadmium (Cd), in sediment samples collected in the UHE Foz do Rio Claro reservoir. To evaluate the levels of contamination, we calculated the geoaccumulation index (IGeo), as well as the oriented values established by Conama Resolution 454/2012 resolution. In general, the elements Cu and Cd presented values above level II for most sampling points, resulting in the classification of bad quality of the sediments analyzed. The Igeo values indicated the contamination of Cu and Cd. This study evidenced the need for frequent monitoring of the sediment quality in the Foz do Rio Claro reservoir, as an indispensable procedure for periodic evaluation of the basin quality, considering their importance for State of the Goiás water supply and energy generation.
