[Determination of metals in biological fluids].

The AA. show the analytical methods which can be used to determine the presence of metals in the biological liquids by means of the atomic absorption spectroscopy. For some metals the analysis can be directly achieved by means of atomisation of the biological liquid in a flame or in a graphite furnace; for other metals it is necessary a treatment of the sample to separate the metal from the rest of the matrix, which can be: calcination, microcalcination, mining. In the final part of this paper, a table is showed with the concentration values in urine, blood, serum of occupationally exposed subjects and not, for the following metals: Al, As, Cd, Co, Cr, Fe, Mn, Hg, Ni, Pb, Cu, Zn.
