CORRELATION OF SPECTOMETRIC METHODS IN HARD TISSUE HEAVY ELEMENTS CONCENTRATION STUDY

Environment monitoring and exposure research are based on direct measurements in humans on samples taken from human tissues and from the environment. The authors have proposed an analysis of Sr, Pb, Cd, Hg, Zn, Fe, Ni, Cr, Mo, Al and Cu concentration in dental tissues (extracted teeth) on samples taken from individuals exposed during recent history in the same area. Using the complementary EDS method coupled to SEM method allows a quantitative compositional analyzes regarding elements that are lighter than Na, which completes the results obtained by EDPXRF. The heavy metal metabolism in the human hard tissues can be assessed by individual studies made on targeted groups from the same living area.Original Abstract: Monitorizarea si cercetarea mediului si a expunerii oamenilor la factori poluanti se bazeazaa pe maasuraatori directe pe probe prelevate din tesuturi umane si din mediu. Autorii si-au propus o analizaa a concentratiei de Sr, Pb, Cd, Hg, Zn, Fe, Ni, Cr, Mo, Al si Cu in tesuturi dentare (dinti extrasi) pe probe prelevate de la persoane expuse in timpul istoriei recente din aceeasi zonaa geograficaa. Folosind metoda complementaraa EDS cuplataa metodei SEM este posibilaa o analizaa compozitionalaa cantitativaa a elementelor mai usoare decat Na, care completeazaa rezultatele obtinute prin EDPXRF. Metabolismul metalelor grele in tesuturile umane dure poate fi evaluat prin studii individuale efectuate pe grupuri tintaa din aceeasi zonaa.
