- W2381228260 abstract "Sepetiba bay, located about 60 km west of the metropolitan region of Rio de Janeiro city, has undergone notable development in the last decades, with the establishment of about 400 industrial plants in its basin, basically metallurgical. These industries release their industrial waste either straight into the bay or through local rivers. The Sepetiba harbor also brought up a lot of industrial investment in that area. This urban and industrial expansion caused several environmental impacts, mainly due to the presence of metals, metalloids (such as As) and other potentially toxic substances present in the effluents discharged into the bay. In this work, Neutron Activation Analysis (NAA), Graphite Furnace Atomic Absorption Spectrometry (GFAAS) and Inductively Coupled Plasma – Optical Emission Spectrometry (ICP OES) were used to determine As, Cd, Cu, Ni, Pb and Zn concentration in sediment samples from Sepetiba bay. The results obtained were treated by using Factor Analysis with Extraction Principal Components. This statistic method has been commonly used in geochemical studies to identify sources of several elements in environmental samples, separating the anthropic contributions from the natural ones. According to eigenvalues, 2 principal components explain 71% of the total variance. The factor loadings indicated that Cu, Pb and Ni presented good correlation to sediment grain sizes and organic carbon and were associated to first factor (F1), while As, Cd and Zn were associated to second factor (F2). The results suggest that these elements have different sources." @default.
