Background. Concentration of trace elements in the hair allows to get an idea how they are taken by the organism over a long period of time and to study relative correlations with different genetic, dietary and environmental factors. Research aim was to identify changes in the macro- and microelement status for young athletes involved in different sports activities depending on the preparation period within one-year training cycle. Methods. A total of 78 young athletes aged 12–17 years, 32 of which were swimmers (group I), 17 – tennis players (group II) and 29 – Taekwondo athletes (group III) participated in the study. Biological material (hair samples), the volume of 0.1–0.15 g were taken for experimental studies in three periods of time: preparatory, competitive and transition period within a one-year training cycle. Hair samples were analyzed using the method of X-ray fluorescence (XRF) in order to detect multiple elements. For quantitative analysis, 8 chemical elements (sulfur, potassium, calcium, iron, copper, zinc, strontium and selenium) were determined in a single hair sample. Results and conclusion. A non-invasive method to determine mass fraction of the chemical elements (sulfur, potassium, calcium, iron, copper, zinc, lead, chlorine, bromine, strontium, selenium) in a hair sample is an informative method for assessing the physiological response of the body (young athletes) with physical activity at different stages of training. The statistical analysis of the obtained results revealed the dependence of the concentration of trace elements from a kind of sports activity and stage of preparation for young athletes.

This research looks at the correlation between the quantity of nutrients taken as minerals determined by PIXE analysis and mineral intake calculated in accordance with menu records collected via a total food duplicate method survey conducted on agricultural workers from four inland areas of Iwate Prefecture. Among the major nutrients and minerals taken over a 24 h period, intakes of calorie and carbohydrate of both sexes were found to be slightly high for the off-season, which indicated they had kept on a diet suited for the busy farming season. Intakes of calcium, iron and dietary fiber were also high. While 31 elements were identified from the hair samples collected from subjects, the elements found in all subjects were sulfur, calcium, iron, copper, zinc, and bromine. In many of the elements detected, a great difference between the maximum and minimum values was found. As for potassium, sodium, calcium, magnesium, phosphorus, iron, copper, of which excess or deficiency could affect health, we examined whether their element content in hair correlates with their amount taken in the body through meals. However, no clear correlation between the two, the elements in hair and meals, was found.

Trace elements in squid statoliths were analyzed by PIXE for the following fourteen species in five families of different habitat origin: Ommastrephidae, Ommastrephes bartrami, Dosidicus gigas, Sthenoteuthis oualaniensis; Gonatidae, Gonatopsis makko, G. borealis, Berryteuthis magister; Loliginidae, Loligo bleekeri, L. duvaucelii, L. chinensis, L. edulis and Sepioteuthis lessoniana; Sepiidae, Sepia aculeata and Sepiella inermis; Sepiolidae, Rossia pacifica, Manganese, iron, copper, zinc and strontium were detected from statoliths of all species examined. Among these trace elements, Sr is the highest in concentration. Variation of statoliths Sr concentration reflects taxonomic position and the habitat of specimens. In Ommastrephids and Gonatids, that have oceanic habitat, statoliths Sr concentration is relatively high whereas that of Loliginids and Sepiids, that have coastal habitat, is comparatively low. This fact supports our previous report on this subject. R. pacifica exceptionally shows high statoliths Sr concentration although this species inhabits in coastal water.

Slags sourced from a derelict zinc–lead–copper–silver–tungsten mine were examined for their bulk elemental composition and mineralogy. pH, oxidation–reduction potential, and the leachability of selected elements (sulphur, calcium, iron, copper, zinc, and lead) were assessed during a 130-day deionised water extraction conducted under oxic conditions. Slags were rich in silicon, iron, copper, zinc, and lead, hosted within minerals including quartz (SiO2), goethite [FeO(OH)], augite [Ca(Mg,AI,Fe)Si2O6], and lead (Pb0). Leachates from the slags increased in analyte concentration throughout the 130-day experiment, with iron, copper, zinc, and lead attaining >5 mg l−1 in some samples. These findings indicate that this pyrometallurgical waste should not be considered environmentally inert, as leachates emanating from them in the field might pose a significant risk to the environment.

Acupuncture and moxibustion are commonly accepted treatments in traditional Chinese medicine (TCM). One of the important issues of interest is determining the accurate location of acupoints in acupuncture. Modern high-technology methods were utilized to verify the accuracy of acupoint positions in TCM, reducing the uncertainty of manually locating the positions. The acupoint location was established according to the richness of trace elements (TEs). The relative content of TEs was perceived by X-ray fluorescence (XRF) analysis. The distribution of TEs was determined after the dates were calibrated and the processes were optimized. The relative content of TEs was significantly different in acupoint and non-acupoint areas. There was an uneven distribution of calcium, iron, copper, and zinc in the sample. The relative content of these elements was increased in the acupuncture areas, and the standard deviation was also relatively large, especially for calcium, showing obvious enrichment. According to the enriched area of the TEs, the distance was about 6 mm between the conception channel and the kidney meridian, and the distance to the stomach meridian was about 23 mm for the rabbit sample. The position of the acupoints and spacing of meridians, which were determined according to the enrichment of TEs, were consistent with the TCM theory. The results show that synchrotron radiation-based XRF is a suitable method for determining the location of acupoints.

It is recognised that, in addition to those chemical elements which are known to be necessary and essential constituents of protoplasm, others have a wide distribution in living matter. Such are iron, copper, zinc, aluminium and manganese. Besides these, a number of additional elements have been recorded as occurring spasmodically in animal and plant tissues. Hitherto the spectro-scope has rarely been used as a method of detecting uncommon elements in animal tissues; yet the spectroscope supplies a valuable tool for making a wide survey of tissue contents with a rapidity of which chemical methods do not allow. The present paper is the first report on such a survey, carried out on a quantitative basis. The field to be covered is, of course, vast. As a beginning, we have restricted ourselves mainly to annelids, in which whole animals were analysed, and molluscs, the separate organs of which were dissected out and dealt with. In addition, a limited amount of other material has been studied, including human organs, insects, and a few representatives of other groups. As the work progresses it is intended to investigate the principal divisions of the animal kingdom.

In the article we studied chemical elements in the hair of children as a form of environmental monitoring of metals in a given area, since one of the objective indicators of the ecological and hygienic well-being of a territory is the status of trace elements as the most sensitive part of the population, especially children. Many foreign scientific studies have shown that a hair sample is a good indicator of a negative technogenic impact on humans, and it is known that the unfavorable state of children characterizes the ecogeochemical features of the area, so we took into account the accumulation of trace elements in the hair. The study showed an increase in lead and cadmium and a decrease in zinc, copper and chromium.

Background: This study aims to determine and compare the levels of trace elements copper, zinc, selenium and chromium in GCF and serum of patients with periodontitis and healthy individuals. Methods: This cross sectional study includes 24 study subjects recruited from the patients reporting to the Department of Periodontics , Tagore Dental College Chennai. All the selected patients were subjected to a clinical examination done by a single examiner. The estimation of trace elements Copper, Zinc, Selenium and Chromium in GCF and serum is performed using Perkin Elmer optima 5300 Inductively Coupled Plasma Emission Spectrometer (ICPOES). Results: GCF and serum copper levels showed no significant difference in both periodontitis and healthy groups . Selenium levels tend to be the same in both groups. Serum zinc levels are more in periodontitis patients than healthy subjects (p less than 0.01). GCF chromium levels are found to be more in patients with periodontitis than healthy. Conclusions : More research is therefore needed to monitor the role of these trace elements C with an increased sample size to ascertain whether they are associated with a reduced risk of periodontitis.
