Sumario:Diana Island is a neighborhood inserted in the Santos/São Paulo State and is home to approximately 210 people. There are no published studies on local environmental variables, although the neighborhood is bordered by the Diana River, affected by the tide entering the estuary. This research aimed to analyze the levels of metals accumulated in soil samples collected in the neighborhood, using the X-ray fluorescence method as a screening technique. The results showed that the island presents soil contamination for chromium (Cr), cobalt (Co), zinc (Zn), molybdenum (Mo), cadmium (Cd), barium (Ba), and lead (Pb), in addition to anomalies in concentrations for iron (Fe) and manganese (Mn). Through distribution patterns, it was possible to determine two different types of sources of contamination and their potential cause. This is a pioneering study on the levels of local metals that can serve as a parameter for future studies of contamination in Diana Island's soil.
