Aspectos Fitoquímicos e Contaminação Antrópica por Metais nas Bacias Hidrográfica do RIBEIRÃO SANTO ANTÔNIO NO MUNICÍPIO DE APARECIDA DE GOIÂNIA - GO

Abstract

The current work aims to analyze the concentration of chemical elements in samples of sediment in the draining chain of the Ribeirão Santo Antônio’s watershed in the region of Aparecida de Goiânia - in the area surrounding Goiânia-GO, and also analyze the Lettuce and Borecole grown there, to investigate the possibility of environmental, anthropic and natural contaminations; establishing a correlation with human being’s health. Sixteen samples of chain sediment were analyzed by (AA) and seven samples by (ICP); nine samples of Lettuce were analyzed by (ICP) and nine samples of Borecole also analyzed by (ICP), adding up forty-one samples. After analyzing the results of the concentrations of the chemical elements, matrices of correlation were generated from these results. Subsequently, geochemical associations were defined; and the maps of distribution of the selected chemical elements were made according to the biological action of each element that was found. The results show high concentrations of Au, Cd, Ba, La, Li, Mg, Ni, K, Zn, Rb, Tl, Cs, Cr, Sb, Fe, Th, Mn, As, Co which are chemical elements related to natural contamination and anthropic components This accrues because the area in study is widely populated and the immense misuse of the water for irrigation of greens and so on; exposing the population to risk of contamination.
