“…Current conventions in ICP-MS for quantitative analyses of clinical samples include internal standardization, use of collision/reaction cells and matrix-matched calibrations. Normally, internal standards are used to correct for short term and long-term drift, while reaction/collision cells and matrix-matched calibration curves can help account for spectral and non-spectral interferences [ 44 , 45 , 46 ]. However, it should not be overlooked that the strategies themselves can impact the accuracy of the results.…”

Rare earth elements (REEs) have undergone a steady spread in several industrial, agriculture and medical applications. With the aim of exploring a sensitive and reliable indicator of estimating exposure level to REEs, a simple, accurate and specific ICP-MS method for simultaneous direct quantification of 15 REEs (89Y, 139La, 140Ce, 141Pr, 146Nd, 147Sm, 153Eu, 157Gd, 159Tb, 163Dy, 165Ho, 166Er, 169Tm, 172Yb and 175Lu) in human urine has been developed and validated. The method showed good linearity for all REEs in human urine in the concentrations ranging from 0.001–1.000 μg∙L−1 with r2 > 0.997. The limits of detection and quantification for this method were in the range of 0.009–0.010 μg∙L−1 and 0.029–0.037 μg∙L−1, the recoveries on spiked samples of the 15 REEs ranged from 93.3% to 103.0% and the relative percentage differences were less than 6.2% in duplicate samples, and the intra- and inter-day variations of the analysis were less than 1.28% and less than 0.85% for all REEs, respectively. The developed method was successfully applied to the determination of 15 REEs in 31 urine samples obtained from the control subjects and the workers engaged in work with manufacturing of ultrafine and nanoparticles containing cerium and lanthanum oxide. The results suggested that only the urinary levels of La (1.234 ± 0.626 μg∙L−1), Ce (1.492 ± 0.995 μg∙L−1), Nd (0.014 ± 0.009 μg∙L−1) and Gd (0.023 ± 0.010 μg∙L−1) among the exposed workers were significantly higher (p < 0.05) than the levels measured in the control subjects. From these, La and Ce were the primary components, and accounted for 88% of the total REEs. Lanthanum comprised 27% of the total REEs while Ce made up the majority of REE content at 61%. The remaining elements only made up 1% each, with the exception of Dy which was not detected. Comparison with the previously published data, the levels of urinary La and Ce in workers and the control subjects show a higher trend than previous reports.

“…The deionized water was obtained using Arium Pro DI Type 1 Ultrapure Water Quality Systems (Sartorius AG, Göttingen, Germany). The deionized water was selected as a controlled sample or a blank solution to be compared to the other types of water due to its very low mineral content (Mazurova et al, 2015). The tap water was obtained from food pilot plant of Universiti Kebangsaan Malaysia.…”

The aim of this study was to evaluate the physicochemical properties of cassava starch that was processed using different parameters (types of water, drying temperatures and milling sizes) to be added into the food products as an ingredient. Selected commercial cassava starch was used as a reference. Mineral water showed a significantly higher value (p<0.05) for the paste viscosity of cassava starch compared to the other types of water, but indicated no significant difference (p>0.05) with tap water for the swelling power, solubility and gel strength of cassava starch. The increase in the drying temperature significantly decreased (p<0.05) swelling power, paste viscosity and gel strength of cassava starch but significantly increased (p<0.05) its solubility. The increase in the milling size significantly increased (p<0.05) swelling power and solubility, paste viscosity and gel strength of cassava starch. For industrial benefits, the use of mineral water for starch processing, the lowest drying temperature of 70°C and the largest milling size of 63 μm shall be the best processing parameters to produce cassava starch with the highest swelling power which could act as a reliable expansion aid in food products. These parameters shall also be the best processing parameters to produce cassava starch with the highest paste viscosity which could function as a desirable food thickening or gelling agent, as well as the highest gel strength that could be applied as an excellent texture enhancer, binder, or coating for food products.

“…The toxicological aspect of drugs is also important because of the elemental impurities they contain as well as the benefits it provide to the living metabolism. For this reason, various analytical methods such as inductively coupled plasma-optical emission spectroscopy (ICP-OES) [9][10][11][12][13], inductively coupled plasma-mass spectroscopy (ICP-MS) [14][15][16][17][18][19][20], atomic absorption spectroscopy (AAS) [21,22], graphite furnace atomic absorption spectroscopy (GFAAS) [23] and flame atomic absorption spectroscopy (FAAS) [24], which are extremely important in the determination of elemental impurities in drugs, have been developed. When these analytical methods in the literature are examined from a scientific point of view, ICP-MS and microwave-assisted digestion, which is one of the sample pre-processing methods, come to the fore when compared to other methods mentioned.…”

The drug, one of the most important products that cannot be replaced in the field of health, prevents all threats to human health when used in place and dosage. Therefore, it has an important place in public health. Determination of the amounts and impurities of various elements used in drug production is an important parameter. According to the ICH Q3D(R1) international compliance conference guide, methods by which limit concentrations can be determined for elemental impurities by applying inductively coupled plasma (ICP) analysis to drugs are specified. In this study, the sample preparation step in the analysis of 23 elements in cancer and allergy drugs in tablet form was optimized by microwave digestion, and method development and validation studies were carried out for these drugs with inductively coupled plasma-mass spectrometry (ICP-MS). When the analysis results were evaluated, it was seen that the data obtained were by the limit values specified in the ICH. Detection and quantification limits of the developed method, and relative standard deviation values were determined, and recovery studies were carried out by adding standards at 4 different concentrations to determine the method's precision. The correlation coefficients obtained for heavy metals in this study ranged from 0.9993 to 1.000, while the detection limit was found to be between 0.001 and 1.756 µg/L. Thus, the reliability and precision of the validation study developed has been determined and it has been shown that this method can be used in similar drug samples.
