Aim. In order to establish the dependence of the threat preterm birth in pregnant women on the concentration of macro- and micronutrients, a comparative analysis of blood was carried out in 92 pregnant women aged 19 to 37 before and after treatment. Materials and methods. Quantitative elemental analysis of blood serum was performed for 8 elements: Ca, Cu, Fe, K, Mg, Na, Zn, Se using the method of inductively coupled plasma atomic emission spectrometry (ICP MS 7700e, Intertech. Corp., USA). Results. The conducted macro- and microelements content analysis revealed that during pregnancy, childbirth and perinatal period, a violation of their quantity is of no small importance. Conclusions. A reliably significant dependence of the threat of abortion, hypoxia, intrauterine growth retardation on the balance of macro- and microelements was noted.

AbstractThe possibility of using inductively coupled plasma atomic emission spectrometry (ICP-AES) to determine the elemental composition of archaeological bones elements was evaluated and discussed. The interferences of the major elements (Ca, P, K, Na, Al and Fe) on the microelements (Ba, Cd, Co, Cr, Cu, Mn, Ni, Pb, Sr, Zn) were investigated and the appropriate analytical lines were selected. The role of different nebulizers (cross-flow, Babington and Meinhard) on detection limits were investigated. The applicability of the proposed procedure was demonstrated analyzing IAEA-SRM-H-5 (Animal bone); and authentic bone sample dating back to the 4th century BC. These results were compared to ETAAS and ICP-MS.

<p class="Default">This study presents the spatial distribution of 69 elements in the surface water of the Bregalnica river basin. The concentration of elements was determined using inductively coupled plasma with mass spectrometry (ICP-MS) and inductively coupled plasma - atomic emission spectrometry (ICP-AES). The data summary results were reduced with the application of multivariate factor analysis, whereupon three dominant geochemical associations were obtained: F1 (Ca-K-Mg-Na-Ba-Li-Mn-Sr-V), F2 (Al-Fe) and F3 (Sb). Anthropogenic enrichments of Pb and Zn occur in the Pb-Zn mine area. The obtained data exceeded the maximum allowed concentrations in accordance with the national regulation for surface water quality. Trace elements including REEs were significantly correlated with the dominant geological formations characteristic of the different sub-regions in the investigated area.</p>

The purification of polyether polyols with low unsaturation was studied. The removal effect of residual double metal cyanide in the polyols by the methods of adsorption and precipitation-filtration is characterized by the residual concentration of the zinc and cobalt ions which is measured by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). Compared with precipitation-filtration, the method of adsorption was more practical and efficient for the purification of the polyols. And the optimum kind and amount of the adsorbent were obtained. The results showed that the combination of chelating fiber and attapulgus clay was the most favorable for the removal of zinc and cobalt ions and the appropriate weight ratio of chelating fiber and attapulgus clay was 1:1. The total concentration of zinc and cobalt ions can be reduced to lower than 1×10-6. And the amount of the adsorbent added was 3.33% by the weight of the polyether polyols. And through Scanning Electron Spectroscopy (SEM) the morphology of the chelating fiber was characterized before and after adsorption.

Calibration by the concentration ratio provides better metrological characteristics compared to other calibration modes when using the inductively coupled plasma atomic emission spectrometry (ICP-AES) for analysis of geological samples and technical materials on their base. The main reasons for the observed improvement are: i) elimination of the calibration error of measuring vessels and the error of weighing samples of the analyzed materials from the total error of the analysis; ii) high intensity of the lines of base element; and iii) higher accuracy of measuring the ratio of intensities compared to that of measuring the absolute intensities. Calcium oxide is better suited as a base when using calibration by the concentration ratio in analysis of carbonate rocks, technical materials, slags containing less than 20% SiO2 and more than 20% CaO. An equation is derived to calculate the content of components determined in carbonate materials when using calibration by the concentration ratio. A method of ICP-AES with calibration by the concentration ratio is developed for determination of CaO (in the range of contents 20 – 100%), SiO2 (2.0 – 35%), Al2O3 (0.1 – 30%), MgO (0.1 – 20%), Fe2O3 (0.5 – 40%), Na2O (0.1 – 15%), K2O (0.1 – 5%), P2O5 (0.001 – 2%), MnO (0.01 – 2%), TiO2 (0.01 – 2.0%) in various carbonate materials. Acid decomposition of the samples in closed vessels heated in a HotBlock 200 system is proposed. Correctness of the procedure is confirmed in analysis of standard samples of rocks. The developed procedure was used during the interlaboratory analysis of the standard sample of slag SH17 produced by ZAO ISO (Yekaterinburg, Russia).
