| Abstract | The concentration levels of Pb, As, Cd, Se, and Cr in wastewater of Riyadh second industrial city environment were monitored using ICP-MS. Samples were collected from five different reservoirs three times a day for a period of four weeks during the summer season. Precision and accuracy study for the analysis of industrial wastewater were obtained by spiking the samples with the elements of interest and percentage recoveries for those elements were calculated. Results were obtained using external standard calibration with the addition of Yttrium (Y) as internal standard. The percentage recovery for all elements are ranging between 93% to 102% and the relative standard deviation for almost all elements in the samples were ranging between 0 to 12%. Results were calculated and compared with the maximum allowable concentrations ruled by the Royal Commission of Jubail and Yanbo (RCJY) at Saudi Arabia.
