dc.description.abstractThe study of the metal distribution in sediments is very important from the point of view of environmental pollution. One of the objectives of the study of metal pollution in estuarine sediments is the historical record of anthropic activity. Ponte Nova reservoir, located in the upper basin of the Tietê River in the southern region of São Paulo State, covers an area of 25.7 km2 and drains an area of 320 km2. A sediment core was collected in the dam in August 2018 and in February 2019, sliced at every 2.5 cm, totalizing 13 samples in August and 17 samples in February 2019. Instrumental neutron activation analysis (INAA) was applied to the sediment samples to determine some major (Fe, K and Na), trace (As, Ba, Br, Co, Cr, Cs, Hf, Rb, Sb, Sc, Ta, Tb, Th, U and Zn) and rare earth (Ce, Eu, La, Lu, Nd, Sm, Tb and Yb) elements. Inductively Coupled Plasma – Mass Spectrometry (ICP-MS) was applied to determine (Cd, Cu, Mn, Ni, P and Pb). The results were evaluated by comparison to Canadian Sediment Quality Guidelines (TEL and PEL) and by the enrichment factor (EF) in relation to background values. EF>1.5 was obtained for As in both campaigns. In comparison to guidance values from Canada, Cr and Pb exceeded TEL in some superficial samples. Other elements analysed did not show enrichment factors >1.5 and the results were below TEL, indicating that there is not an important anthropogenic contribution of the analyzed elements in the reservoir.pt_BR
