Assessment of Toxic, Essential, and Other Metal Levels by ICP-MS in Lake Eymir and Mogan in Ankara, Turkey: An Environmental Application

Yuksel, Bayram/0000-0001-7686-8648WOS: 000452655600001The goal of this study was to develop and validate a sensitive ICP-MS method for the determination of some toxic metals (Al, As, fig, Pb, Cd. Ni. Cr, and Sb), along with essential and other elements (Fe, Cu, Zn, Mn, Se, Co, and Ti) in water samples collected from 20 sites of Lake Eymir and lake Mogan in Ankara, Turkey. The mean metal concentrations, except for As, in the water samples of the two lakes were found at safe levels. The As levels in Lake Mogan (12.15 +/- 0.41 mu g/L) and Lake Eymir (11.49 +/- 0.66 mu g/L) were higher than the permissible limits recommended for drinking water of 10.0 mu g L-1 As. The "significance" of this paper fundamentally addresses the assessment of general signal optimization for multi-element analysis and reducing interferences during validation and optimization of this ICP-MS method. Good linearity with a correlation coefficient between 0.9911 and 1.000 was obtained, respectively. Imprecision was measured as the coefficient of variation (CV), which ranged between 1.16% and 4.79%. Recovery of the method was between 97.3% and 103.6% for all elements, which supports the accuracy of the method. The procedure described is relatively simple, precise, and applicable for mutine environmental metals analysis in natural water samples
