APPLICATION OF ATOMIC ABSORPTION SPECTROSCOPY IN HUMAN BODY AND WATER ANALYSIS

The methods and techniques to determine the 26 elements in human body and water be the practical use of atomic absorption spectroscopy are described in the paper. Surface water ( river and lake ) , whole blood, serum, urine, stomach fluid and human tissues are analysed. The elements determined are Be, Cr(II), Cr (VI) , Co, Ni, Mo, V, Cd. Fe, Mn, Sr, Ba, K, Na, Ca, Mg, Cu, Zn, As, Sb, Se, Sn, Bi, sum mercury , organic and inorganic mercury, direct flame AAS, solvent extraction flame AAS, heated nebuliza-tion chamber flame AAS, microsampling flame AAS, furnace AAS ( including graphite furnace lining with tantalum foil),tantalum boat AAS, hydride generation AAS and cold vapor AAS are used for analyses.
