ICP-MS and ICP-OES instrumental conditions were optimized for the determination of Li, Be, B, AI, V, Cr, Mn, Fe, CO, Ni, Cu, Zn, As, Se, Rb, Sr, Ag, Cd, Sb, CS, Ba, Hg, TI, Pb, and Bi to achieve low detection limits (DLs) and good precision. Routine ICP-MS and ICP-OES DLs were in the 0.01-2.0 ug/L and 0.7-25.0 ug/L range, respectively. Precision was evaluated at one sigma relative standard deviation (RSD) for three replicate sets of analyses. Accuracy was evaluated by analysis of certified reference materials for water (SRM 1643c and SLRS-3), using the standard additions method for natural waters having a different chemical composition and total dissolved solids up to 10 g/L. Precision and accuracy of most elements at concentrations above the ug/L level were <10%. ICP-MS precision of <19% was observed at concentrations of 0.03 ug/L, while sub-ug/L concentrations for the elements considered could not be determined by ICP-OES.

Abstract
ICP-MS and ICP-OES instrumental conditions were optimized for the determination of Li, Be, B, AI, V, Cr, Mn, Fe, CO, Ni, Cu, Zn, As, Se, Rb, Sr, Ag, Cd, Sb, CS, Ba, Hg, TI, Pb, and Bi to achieve low detection limits (DLs) and good precision. Routine ICP-MS and ICP-OES DLs were in the 0.01-2.0 ug/L and 0.7-25.0 ug/L range, respectively. Precision was evaluated at one sigma relative standard deviation (RSD) for three replicate sets of analyses. Accuracy was evaluated by analysis of certified reference materials for water (SRM 1643c and SLRS-3), using the standard additions method for natural waters having a different chemical composition and total dissolved solids up to 10 g/L. Precision and accuracy of most elements at concentrations above the ug/L level were <10%. ICP-MS precision of <19% was observed at concentrations of 0.03 ug/L, while sub-ug/L concentrations for the elements considered could not be determined by ICP-OES.
