  1. Content of the selected trace elements (Al, As, Cd, Cu, Fe, Hg, Mn, Ni, Pb, Zn) in blood, urine and hair of blood donors without occupational exposure to these metals.

    Article - En anglais

    The trace element content in biological samples from blood donors (BD) has not been studied in detail so far.

    In everyday practice minimum attention is paid to the occupational history of blood donors from different social strata.

    In addition to clinical and elementary haematological and biochemical examinations, the authors assessed levels of Al, As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, and Zn using atomic absorption spectrophotometry (AAS) in two groups of BD - from the Ovara (n=19) and Prievidza region (n=29).

    The examined blood donors were never exposed to the risk of metal exposure.

    No significant differences were found in age and smoking habits between the groups.

    In analyses electrothermic atomization (AAS-GTA) was mostly used.

    Hg in urine was assessed, using the technique of hydride vapour formation (VGA).

    Comparing the results of both BD groups, using Student's t-test, some significant differences between the two regions were found in As, Pb, Cr, Cd, Mn, Ni levels.

    The authors discuss the possible influeznce of artifical metal sources from the plants contaminating the environment of the regions for prolonged periods (power plant using coal containing As, metallurgy plant producing ferrochromium and ferromanganese alloys and lead metallurgy plant.
