Resumo: | The objective of this research was to make a preliminary assessment of environmental conditions with respect to the contribution of metals concentrations in the mangrove river sediment Passa Vaca, Salvador (BA). The metals were determined chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), nickel (Ni), barium (Ba), strontium (Sr), vanadium (V) and zinc (Zn). Surface sediment were collected at four points (P1, P2, P3 and P4) of the mangrove major anthropogenic influences. The samples were pre-treated by acid digestion and the determinations of metallic elements was by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP OES). The results reported values higher concentrations at point P4 concentrations for the Fe (28,101.65 µg g-1), followed by V (62.96 µg g-1), Mn (60.57 µg g-1) and Cr (53.09 µg g-1), while at point P2 higher concentration was found to Zn (47.95 µg g-1) P2. The correlation analysis and principal component (PCA) revealed a strong correlation between the metals studied among the finer fractions of the pellet and the elements Fe, Cr and Ni. Taking into account the values of the thresholds of adverse effects (TEL) of NOAA, the concentrations of Cu and Cr in P4, outperformed this index. |

Os metais determinados foram cromo (Cr), cobre (Cu), ferro (Fe), manganês (Mn), molibdênio (Mo), níquel (Ni), bário (Ba), estrôncio (Sr), vanádio (V) e zinco (Zn). Sedimentos superficiais foram coletados em quatro pontos (P1, P2, P3 e P4) do manguezal com maiores influências antrópicas. As amostras foram pré-tratadas por digestões ácidas e as determinações dos elementos metálicos realizadas por espectroscopia de emissão ótica com plasma indutivamente acoplado (ICP OES). Os resultados reportaram maiores valores de concentrações no ponto P4, para o Fe (28101,65 µg g-1), seguido de V (62,96 µg g-1), Mn (60,57 µg g-1) e Cr (53,09 µg g-1), enquanto que no ponto P2 foi encontrada maior concentração de Zn (47,95 µg g-1). A análise de correlação e de componente principal (PCA) revelou forte correlação entre os metais estudados entre as frações mais finas do sedimento e os elementos Fe, Cr e Ni. Levando-se em consideração os valores dos efeitos limiares de efeitos adversos (TEL) do NOAA, as concentrações de Cu e Cr, em P4, superam este índice.Universidade Federal de Campina Grande - UFCG2017-05-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/4410.22571/Actabra12201744Acta Brasiliensis; Vol 1 No 2 (2017): Acta Brasiliensis; 1-7Acta Brasiliensis; Vol 1 No 2 (2017): Acta Brasiliensis; 1-7Acta Brasiliensis; Vol 1 No 2 (2017): Acta Brasiliensis; 1-72526-43382526-432Xreponame:Acta Brasiliensis (Online)instname:Universidade Federal de Campina Grande (UFCG)instacron:UFCGporhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/44/19Copyright (c) 2017 Acta Brasiliensisinfo:eu-repo/semantics/openAccessSantos, Leila Maria MendesSouza, Rosemário CequeiraAnunciação, Daniela SantosViana, Zenira Cardoso VilasboasSantos, Vera Lúcia Câncio Souza2021-07-12T20:04:20Zoai:ActaBra.revistas.ufcg.edu.br:article/44Revistahttp://revistas.ufcg.edu.br/ActaBraPUBhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/oaiactabrasiliensis@gmail.com || actabrasiliensis@gmail.com2526-432X2526-4338opendoar:2021-07-12T20:04:20Acta Brasiliensis (Online) - Universidade Federal de Campina Grande (UFCG)false |
