The aim of the study was to obtain an oil extract with the participation of chamomile officinalis (Matrigaria Recutito) grown in the Tashkent region using bitter almond oil (Amygdalus communis L.). Its chromatographic and elemental analyzes have been carried out, its microbiological purity and physicochemical constants have been determined. For extraction, we used bitter almond oil obtained by cold pressing. Extraction of chamomile flowers in bitter almond oil was carried out by maceration in the ratio of raw material: solvent (1:10). Analysis of fatty acids in the fatty extract was carried out chromatographically. The fatty extract was found to contain 74.87% oleic acid, 16.97% linolenic acid and 7.62% of the total saturated acids. The elemental composition of the extract was analyzed by inductively coupled plasma mass spectrometry and found to contain 20 different elements. The physicochemical properties and microbiological purity of the obtained oil extract were studied

The biomass ofVaucheria sessilisforms algal mats in many freshwaters. There is a need to find the method of algal biomass utilization.Vaucheria sessilisis a rich source of micro- and macronutrients and can be used as a soil amendment. In the paper, the elemental composition of enriched, via bioaccumulation process, macroalga was investigated. For this purpose, two independent techniques were used: scanning electron microscopy with an energy dispersive X-ray analytical system (SEMEDX) and inductively coupled plasma optical emission spectroscopy (ICP-OES). The biomass was exposed to two microelemental solutions, with Cu(II) and Zn(II) ions. After two weeks of the experiment, macroalga accumulated 98.5 mg of Zn(II) ions in 1 g of dry biomass and 68.9 mg g−1of Cu(II) ions. Micrographs performed by SEM proved that bioaccumulation occurred. Metal ions were bound on the surface and in the interior of cells. Mappings of all cations showed that in the case of the surface of biomass (biosorption), the elements constituted aggregations and in the case of the cross section (bioaccumulation) they were evenly distributed. The algal biomass with permanently bound microelements can find an application in many branches of the industry (feed, natural fertilizers, etc.).

Background: Bronze spears are weapons with unique regional characteristics of the Shu culture, Southwest China in the Bronze Age, which reflect the bronze manufacturing tradition and the utilization of mineral resources of ancestors. Previous studies mainly focused on the classification, the alloy composition or the production of bronze spearheads of the Shu culture. The purpose of this paper was to make a comprehensive discussion on the Shu culture from the aspects of the relationship between typology and scientific characteristics, the differences in metal raw material selection with the Ba culture, and the contact with the culture in the Central Plains. Results : Methods: In this study, typology, portable X-ray fluorescence spectrometry (pXRF) and multi collector inductively coupled plasma mass spectrometry (MC-ICP-MS) were used to analyze thirteen bronze spearheads unearthed from Shuangyuan site, an Eastern Zhou cemetery in Chengdu City, Sichuan Province, Southwest China. Methods: The results show that the spearheads can be classified into three types in typology. All samples are tin-lead ternary bronzes, and the lead isotope data indicate the lead ore. Most spearheads show ordinary lead and only one spearhead has highly radiogenic lead. Conclusion: The typical Shu-style bronze spearheads have distinct shapes but similar ore materials. Meanwhile, people of the Ba culture and the Shu culture used different metal sources to make bronze spearheads. In addition, a very special bronze spearhead suggests that ancestors of the Shu culture in the Eastern Zhou Dynasty imitated the late Shang culture in the Central Plains.

Herb-mate is a raw material of great importance to Southern Brazil, considering its annual production of approximately 650,000 tons of leaves. The hot mate, known as chimarrão, is the most appreciated beverage and its consumption is linked to the traditions and cultural habits predominantly in the south of the country. Considering its huge importance, the objective of the work was to evaluate the production of laboratory herbmate for chimarrão in order to establish a comparison with the products available on the market. Therefore, it was considered the current legislation and the analysis of its organoleptic and granulometric properties, humidity level and concentration of some toxic metals quantified by inductively coupled plasma optical emission spectrometry. The manufacturing of the final product was made in three steps: first of all, the leaves were submitted to direct fire, then they were dried at a temperature of 40 Cº for 24 hours and, finally, they were ground in a knife mill for 10 minutes. The obtained results showed, in most of the analyzed characteristics, a great similarity between the laboratorial and commercial herb, obtaining approval from 90% of chimarrão consumers who participated in the organoleptic tests. However, the coloration was considered darker and can be explained by logistic problems between the plantation and the laboratory. There was also a divergence in the metals analysis, which showed a higher lead and cadmium concentration when compared to the herbs found on the supermarket shelves. Alarming numbers for consumers were found, since the commercial herbs pointed levels above the recommended for all analyzed metals, which indicate the urgent need for better inspection, as well as improved manufacturing practices of the final product and a better raw material cultivation.

The l’Hort de la Boquera site is located in the northeastern part of Iberia and its stone tool assemblage includes up to 25,000 flint artefacts. This is the first approach to the analysis of the raw material through an archaeopetrological study. Results were obtained by use of mineralogi¬cal techniques: macroscopic and petrographic analysis, Scanning Electronic Microscopy (SEM), Micro-Raman and X-Ray diffraction (XRD); additionally, Laser Ablation Inductively Coupled Plasma Mass Spectrometry was applied. It has been possible to discriminate at least four flint categories, the ‘Evaporitic flint type’ (with two local subvarieties – ‘Common evaporitic’ and ‘Garnet’ varieties) that comes from local outcrops of the Ulldemolins Complex, and two flint types that had their origin further afield: the ‘Charophyta flint type’ (coming from the Torrente de Cinca Unit) and the ‘Dark flint type’ (from the La Serra Llarga Formation).These results make this study the most comprehensive analysis of raw materials that has been carried out in the area so far

Salinity Difference

Retrospective determination of the early life history of fish using the microelemental analysis of their otoliths is dependent upon understanding the factors that affect this elemental composition. Here, juvenile Atlantic croaker (Micropogonias undulatus) were reared under different treatments of temperature and salinity to determine their impacts on elemental inclusion rates in otoliths. Solution-based inductively coupled plasma mass spectrometry (ICPMS) was used to measure 21 isotopes in each otolith: isotopic concentrations ranged over seven orders of magnitude, and differed significantly amongst the temperature–salinity regimes. Univariate analyses identified 13 isotopes that contributed to these multivariate differences; the influence of temperature was stronger than that of salinity. Within each treatment there was a significant relationship between otolith microchemistry and otolith size. To some extent this confounded the interpretation of the between-treatment effect of temperature. In contrast, both the otolith and somatic growth rates were similar between the two salinity treatments, indicating that differences in elemental fingerprints were unambiguously related to the salinity difference, probably a response to the elemental concentrations in the tank water. Overall the study highlighted the current poor understanding of the mechanism of contamination of otoliths by trace elements and their incorporation into the otolith microstructure.

Abstract properties such as biocompatibility and proper bioactivity response. The aim of the present study was to investigate the bioactivity of wollastonite-hydroxyapatite (WS-HA) bio-nanocomposite for the treatment of orthopedic prosthesis coatings approaches by adding magnetic nanoparticles (Fe3O4; MNPs) and single walled carbon nanotubes (SWCNTs) to the matrix. Bio-nanocomposite coated on AZ91 for 40 minutes at 40 volts using electrophoretic deposition (EPD) and after that the heat treatment performed at 550-650°C for 1 hour. The coats were incubated in simulated body fluid (SBF) and phosphate buffer saline (PBS) for 28 days to detect and confirm apatite-like layer formation. X-ray diffraction (XRD), atomic force microscope (AFM) and scanning electron microscopy (SEM) techniques were used to characterize the phase and morphology of the coated sample. Inductively coupled plasma optical emission spectroscopy (ICP-AES) tests were used to evaluate the concentrations of calcium and silicon ions. The finding from the present study showed the successful coating with 10 wt% MNPs added to the WS bio-nanocomposite with proper biological and chemical properties. Bio-nanocomposite coating can be considered as a suitable candidate for orthopedic coating applications due to its favorable bioactivity.

The aim of the study was the multi-elemental analysis of aqueous humor (AH) collected from patients undergoing cataract surgery. The study included: 16 patients with age-related macular degeneration AMD (99 controls), 10 patients with retinopathy (105 controls), 61 patients with hypertension (54 controls), and 33 patients with coexisting diabetes (82 controls). The control groups were recruited from patients with a lack of co-existing disease characterizing the specified studied group. The measurements were performed by the use of inductively coupled plasma optical emission spectrometry (ICP-OES). The statistical analysis was carried out using non-parametric testing (Mann–Whitney U). The level of significance was set at p = 0.05. The data obtained revealed substantial variations in elemental composition between the test groups in comparison to the controls. However, the significant variations concerned only a few elements. The phosphorous (P) level and the ratio of P/Ca were significant in retinopathy and diabetes, whereas cobalt (0.091 ± 0.107 mg/L vs. 0.031 ± 0.075 mg/L; p = 0.004) was significant in AMD. In co-existing hypertension, the levels of tin (0.293 ± 0.409 mg/L vs. 0.152 ± 0.3 mg/L; p = 0.031), titanium (0.096 ± 0.059 mg/L vs. 0.152 ± 0.192 mg/L; p = 0.045), and ruthenium (0.035 ± 0.109 mg/L vs. 0.002 ± 0.007 mg/L; p = 0.006) varied in comparison to the controls. The study revealed inter-elemental interactions. The correlation matrices demonstrated the domination of the positive correlations, whereas negative correlations mainly concerned sodium.
