Trace element distribution in geochemical environment of the island Krk and its influence on the local population

Samples of soil, plant material and water collected on the Croatian island Krk in northern Adriatic sea were analyzed for a number of chemical elements (Ca, Ti, Mn, Fe, Ni, Cu, Zn, As, Br, Rb, Sr, Zr, Pb) by using Energy Dispersive X-Ray Fluorescence as an analytical tool. Some of these data have been previously used to produce geochemical map of the island. In addition, trace elements content of hair from children, attending elementary and secondary schools, has been investigated using the same analytical method for the following chemical elements: Mg, S, Ca, Cr, Mn, Fe, Ni, Cu, Zn, As, Hg and Pb. Concentrations of the twelve chemical elements and nine variables from the questionnaire, i.e. age, sex, living place, transportation, medication, hair colour, hair type, type of shampoo used and hair treatment, were considered in the statistical analysis. In this report the observed differences for the seven island's communes have been discussed.
