Chemometric Analysis of Heavy Metals Coexistence in Different Plant Matrices in The Upper Silesian Industrial District / Analiza Chemometryczna Metali Ciężkich Pochodzących Z Różnych Matryc Roślinnych Z Terenów Górnośląskiego Okręgu Przemysłowego

Contents of Zn, Cd, Ni, Mn, Cu, Pb and Fe in 36 samples of Scots pine collected in 9 sites located in the Upper Silesia Province have been determined using AAS technique. The samples were digested before the analysis. On the basis of cluster analysis the existence of links between the quantitative composition, the sampling sites and the type of the matrix have been found. The coexistence of certain groups of elements was found and described.
