In aquatic ecosystems, sediments are reservoirs of heavy metals when their waters are exposed. The purpose of the study was to quantify metals in surface sediments of the interior bay of Puno, Lake Titicaca, Peru. From january to november 2016 of Cu, Zn, Pb, Cd, As and Hg concentrations were analyzed in the surface sediments of six selected environmental sampling stations by non-probabilistic sampling for convenience. The metals were analyzed by acid digestion where their quantification was by inductively coupled plasma spectrometry with axial view (ICP-AES). When comparing the results with the selected environmental standard, all the elements had concentrations in the recommended ranges, although statistically significant differences existed between the stations (p<0,05). The As and Hg, presented similarities in their values (0,0001 mg.L-1) between the stations. As and Hg, presented ...

The inner Puno bay is a restricted area and one of the habitats of Lake Titicaca with high anthropization, where some organic and inorganic elements may be exceeding the thresholds allowable concentrations. The aim of the research was to determine interactively total metals available in the waters of the inner Puno bay of Lake Titicaca, Peru. It was conducted between January and November 2016 by a non-probabilistic for convenience and applying the theoretical method by comparison among six stations of selection. Cu, Zn, Pb, Cd,As, Hg were the determined and quantified elements using atomic absorption spectrometry by inductively coupled plasma with axial view (ICP-AES). It was observed that between the stations there were no statistically significant differences (p ≤ 0.05) when there was an availability of exposure among all the elements, although when comparing each element per station...
