“…Te abundance ratio becomes a constant value when the concentration of the isotopic spike is added to the sample and reaches the equilibrium with the absence of external contamination, and the sample loss in the process of sample separation and concentration does not afect the abundance ratio [6]. Isotope dilution method can greatly eliminate interference and errors caused by sample pretreatment and has thus been confrmed by the Consultative Committee for Amount of Substance: Metrology in Chemistry and Biology (CCQM) as one of the fve methods with absolute measurement properties [7,8]. Tis isotope dilution mass spectrometry originated from the UK Government Chemist Laboratory (GCL) [9,10].…”

In order to evaluate the reliability of the ID ICP-MS method for the measurement of magnesium, zinc, and copper in human serum, we investigated the traceability, precision, trueness, and uncertainty of the method. This method traces the contents of magnesium, zinc, and copper in human serum to the standard materials NIST SRM3131a, SRM3168a, and SRM3114 respectively, thus completing the traceability to SI unit. The repeatability of this method for measuring magnesium, zinc, and copper in the human serum reference material GBW09152 was found to be 0.2%, 0.7%, and 0.6% (n = 9), respectively. The measurement, when employed to measure the magnesium, zinc, and copper in standard materials, had caused a maximum deviation of less than 0.88%, 1.35%, and 1.15%, respectively. The measurement results are within the stated uncertainty range of standard materials. The expanded uncertainties were 0.2 mg·kg−1, 0.04 mg·kg−1, and 0.08 mg·kg−1 (K = 2) for magnesium, zinc, and copper, respectively. Therefore, this method has high trueness, good reproducibility, and simple operation and is suitable for tracing the values of magnesium, zinc, and copper in human serum.

In the present study, trace elements present in the river waters of Sarzhal and Akzhar region were measured using inductively coupled plasma mass spectrometry (ICP-MS). The reason for monitoring trace elements at those two locations is to verify water quality. The village of Sarzhal is situated in an area that has been affected by weapon testing and continues to receive inputs of contaminants (including radionuclides). The concentrations of trace elements in the river water of Sarzhal and Akzhar villages were generally found to be within allowable levels. However, the concentrations of Na 251.56 mg/l, Cr 3.26 µg/l, P 64.56 µg/l and Se 18.162 µg/l in the river of Akzhar were found to be higher than the maximum allowable concentrations (MAC). In Sarzhal, the level of Al 6.66 mg/l, Cr 5.04 µg/l and P 13.44 µg/l exceeded the MAC values.
