Metal contamination in soils of the traditional community of Diana Island, Santos, SP

Abstract:

Diana Island is a community in Santos, in the state of São Paulo, and is home to approximately 210 people. There are no published studies on local environmental variables, although the community is bordered by the Diana River, under direct influence of the tide entering the estuary. This research sought to analyze the levels of metals accumulated in soil samples collected in the community, using the X-ray fluorescence method as a screening technique. The results showed that the island exhibits soil contamination of chromium (Cr), cobalt (Co), zinc (Zn), molybdenum (Mo), cadmium (Cd), barium (Ba), and lead (Pb), in addition to anomalies in concentrations of 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 pioneering study of the levels of local metal contamination may serve as a parameter for future contamination studies of Diana Island soil.
