Interpretation :In view of scarce information, an attempt was made to assess the effect of different media and matrices on the determination of trace toxic elements using an inductively coupled plasma mass spectrometry (ICP-MS). Standof trace toxic elements, viz.Ni, Pb, Cd, and Cr were prepared in water, DTPA(0.005 and 0.0005 M) and EDTA(0.05 and 0.005 M) separately.The concentration of trace toxic elements in the above mentioned solution was measured with ICP-MS.In another objective, standard solution of Zn, Cu, Fe, Mn, Al, Na, K, Ca and Mg were separately added to the standard solution of Ni, Pb, Cd, Cr, and As, so that final concentration of major and trace toxic elements were 50 mg l and 50 g l , respectively.The concentration of standard (50 g l ) Ni, Pb, Cd, Cr and As was measured with ICP-MS.Concentration of these trace toxic elements was also measured in presence of Zn, Cu, Fe, Mn,Al, Na, K, Ca and Mg.Hence, the effect of medium and matrix on measurement of trace toxic elements with ICP-MS was ascertained.
