title: Accumulation of metals in the teeth of inhabitants of two towns in the south of Poland.
abstract: Metals and Ca, Na and K were examined in human teeth taken from inhabitants of two towns Sosnowiec and Katowice in the south of Poland (n = 170 samples) during 1993/1994. They are located in Upper Silesia, a heavily industrialised and urbanised region of Poland. The concentrations of Pb, Mn, Fe, Cd, Cu, Ni, Co, Zn and Cr were determined by AAS, and Na, Ca and K by flame photometer. Variations in the Pb/Fe, Pb/Mn, Pb/Ca and Cd/Ca ratios of elements in human teeth were examined. Influence of age, sex type of teeth on concentrations of elements for inhabitants from the two different towns (Katowice and Sosnowiec) and on levels of ratios of the elements were analysed using one-way ANOVA. Cluster Analysis was used to investigate relationships among metals. The smallest duster distances were obtained for: Ca-Fe, Mn-Cd and Na-Co, which indicated the strongest relation between elements in teeth for the investigated population living in a heavily industrialised and urbanised region.
