Resumo: The present study had the purpose to determine the contents of heavy metals in soil samples of a topolithosequence collected in the Triângulo Mineiro, State of Minas Gerais, in order to test the hypothesis that these elements could be used in the identification and separation of the influence of the parent material. The contents of Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn were determined through two types of concentrated acid attack: HNO3/HClO4 (4:1) and HF/HNO3/HClO4 (20:6:3), and dosed by espectrophotometry of atomic absortion. Procedures of multivariated analysis were used for the statistical data evaluation. The results confirm the hypothesis and permitted to conclude that the heavy metals are indicator of the parent material, being able to be used for the separation and delimitation of the area of their influence. The adopted multivariated techniques proved to be viable for this kind of study only when analysed as a whole.

Os teores de Cd, Cr, Cu, Fe, Mn, Ni, Pb e Zn foram determinados por dois procedimentos de ataque ácido: HNO3/HClO4 (4:1) e HF/HNO3/HClO4 (20:6:3), e dosados por espectrofotometria de absorção atômica. Técnicas de análise multivariada foram utilizadas. Os resultados permitem estabelecer que os metais pesados são indicativos do material de origem, podendo ser usados na separação e delimitação de sua área de influência. As técnicas multivariadas adotadas mostraram-se viáveis nesse modelo de estudo quando analisadas conjuntamente.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraOliveira, Teogenes Senna deCosta, Liovando Marciano daCruz, Cosme DamiãoHorn, Heinrich Adolf1999-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5359Pesquisa Agropecuaria Brasileira; v.34, n.8, ago. 1999; 1451-1465Pesquisa Agropecuária Brasileira; v.34, n.8, ago. 1999; 1451-14651678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5359/2551info:eu-repo/semantics/openAccess2010-07-14T18:26:57Zoai:ojs.seer.sct.embrapa.br:article/5359Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-14T18:26:57Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
