Abstract

Thirteen trace elements in blood serum are determined by using a radiochemical group separation procedure based on acid aluminium oxide, hydrated antimony pentoxide and hydrated manganese dioxide. The method allows the determination of Ag, Co, Cr, Cs, Fe, Hg, Rb, Sb, Sc, Se, Sn, Sr and Zn, which occur in concentrations at the μg g⁻¹ to pg g⁻¹ level. The procedure separates the elements into four groups with matched γ-ray energies and intensities, ensuring reliable and efficient γ-ray measurements. The k₀ method, adapted for the specific sample composition and sizes, was applied. Where possible, results are compared with published data. The results obtained by the relative method are in good agreement with those from the k₀ method, with ⁹⁵Zr⁹⁷Zr, ¹⁹⁸Au and ⁵⁹Fe⁵⁴Mn as neutron flux monitors. The values for the human blood serum reference material agree with the certified values available for most of these elements.

Absorption, distribution, metabolism and excretion (ADME) of oral selenium from organic and inorganic sources: A review
2021, Journal of Trace Elements in Medicine and Biology
Selenium is a trace element traditionally ingested either in its organic form via food or in its inorganic form through nutritional supplements, while selenium formulated as nanoparticles is a putative long-acting alternative. To understand the physiology and toxicology of the different selenium formulations, it is important to determine how their selenium content is absorbed, distributed, metabolised and excreted; therefore, we reviewed their biokinetics following oral exposure.
We retrieved and reviewed the literature on the absorption, distribution, metabolism, and excretion of oral exposure to different forms of selenium.
Selenium in both the organic form (containing carbon to selenium chemical bonds) and the inorganic form is absorbed into the blood in humans. The mean normal blood level of many studies was 139 μg/L. There are indications that selenium from organic sources is more bioavailable than selenium from inorganic sources. Selenium is distributed throughout the body, including in breast milk. The elimination of selenium mainly involves the faecal and urinary pathways, whereas breath, saliva and hair are minor contributors. Urinary metabolites include trimethylselenium ions, selenosugars and Se-methylselenoneine.
Selenium is absorbed to a high extent, and selenium from organic sources is more bioavailable than from inorganic sources. Selenium, as expected as an essential trace element, is distributed throughout the body. Selenium is extensively metabolised, and various excretion metabolites have been identified in both urine and breath, while some selenium is also excreted via faeces.
Determination of trace halogens in rock samples by radiochemical neutron activation analysis coupled with the k<inf>0</inf>-standardization method
2007, Analytica Chimica Acta
Citation Excerpt :
In this study, we propose a new utilization of the k0-NAA in RNAA for the determination of halogens in rock samples. This methodology, RNAA coupled with the k0-standardization method (hereafter, k0-RNAA), was once introduced by Lin et al. [6] for the analysis for human blood serum. The conventional comparison method was also performed at the same time to evaluate the accuracy of the k0-RNAA method in determining trace halogens in rock samples.
Radiochemical neutron activation analysis coupled with the k₀-standardization method (k₀-RNAA method) was applied to silicate rock samples for the simultaneous determination of trace halogens (Cl, Br and I). Analytical results obtained by the k₀-RNAA method for geological standard rocks and meteorite samples agreed with those determined by the conventional comparison method conducted in the same set of experiments, suggesting that the k₀-RNAA method is as reliable as the conventional method. Our data for these samples are in good agreement with their literature values except for rare cases. Detection limits calculated under the present experimental condition are sufficiently low for Cl and Br but not for I for typical geologic and meteoritic samples. The k₀-RNAA method coupled with longer neutron-irradiation is expected to yield satisfactorily low detection limits for halogens including I in these samples.
Trace element reference values in tissues from inhabitants of the European community. VII. Review of trace elements in blood, serum and urine of the Belgian population and critical evaluation of their possible use as reference values
1994, Science of the Total Environment, The
The availability of accurate trace element reference values in human tissues represents an important indicator to the health status of the general population and occupational groups exposed to trace elements. The EURO TERVIHT project (Trace Element Reference Values In Human Tissues) aims to establish and compare trace element reference values in tissues from inhabitants of the European Community as baseline values for clinical/toxicological assessment studies (Sabbioni et al., 1992a,b). In this context one of the first steps considered is the critical evaluation (state of the art) of existing literature on trace element reference values in blood, serum and urine in the general population of each EC country. This paper reviews the Belgian situation.
Chromium
1994, Techniques and Instrumentation in Analytical Chemistry
This chapter discusses the toxicological and environmental significance of Chromium (Cr). Chromium is a common contaminant of the human environment. Possible sources of chromium exposure to the general public are emissions and waste dumps from the industry, causing local air and water pollution. Emissions from fossil-fuel burning also contribute to the atmospheric load. The presence of chromium in phosphates and in municipal sewage sludge used as fertilizers is an important source of Cr in soil, in water, and in some foods. Cr is also a common constituent of laboratory ware and even of ultrapure acids. Freezing and diverse drying techniques are common practice to keep the integrity of the specimens. Some common analytical methods used in the determination of chromium in biological materials are surveyed. The criteria evaluated include precision, sensitivity, specificity, and speed of analysis. The graphite furnace atomic absorption spectrometry (GFAAS) is the most prevalent technique. Flame atomic absorption spectrometry (FAAS) is superseded by GFAAS. Some other methods includes inductively coupled plasma optical emission spectrometry (ICP-OES), inductively coupled plasma mass spectrometry (ICP-MS), neutron activation analysis (NAA), chelate gas chromatography (GC), isotope dilution mass spectrometry (IDMS), X-ray methods such as particle induced X-ray emission (PIXE) and electrochemistry.
Mercury
1994, Techniques and Instrumentation in Analytical Chemistry
This chapter discusses the environmental and toxicological significance of Mercury (Hg). It occurs in nature as a mixture of seven stable isotopes. Two radioactive isotopes, ¹⁹⁷Hg and ²⁰³Hg, are widely used in toxicological studies, radiometric analysis, and in checks of the yield of analytical procedures. Mercury may occur in three oxidation states: elemental or metallic mercury; Hg (0), monovalent mercury; Hg (I), and divalent mercury, Hg (II). The aspects relevant to human exposure are reviewed in the chapter. Fish and marine mammals and birds preying on fish may contain considerable amounts of mercury. Different chemical forms of mercury have different metabolism and toxic effects. The analytical specification of the mercury is crucial. Exposure to elemental mercury vapor may cause effects on the central nervous system, with a change of personality and tremor. Blood is used for biological monitoring of exposure to Hg (0) vapor and MeHg. The type of compound is determinative for the distribution of mercury between blood cells and plasma. Sampling and sample handling are important aspects of any determination of mercury in biological specimens.
Radiochemical neutron activation analysis of Fe, Co, Zn, Sb and Se in biomedical and environmental samples
1993, Science of the Total Environment, The
A radiochemical neutron activation method has been developed for the simultaneous determination of Fe, Co, Zn, Sb and Se levels in cancerous breast tissue, milk samples and fugitive cement dust particulates. Various Standard Reference Materials from NIST, USA (Bovine Liver 1577a, Milk Powder 1549, Coal Fly Ash 1633a and Urban Particulate Matter 1648), IAEA Vienna (Animal Muscle H-4, Milk powder A-11 and Soil-5) and NIES Japan (Pond Sediment) were also analysed for quality control. Samples together with standards were irradiated at a thermal neutron fluence of 10¹³ ncm⁻²s⁻¹ for 2 weeks. After dissolution/fusion together with carriers, the Fe was first separated by extracting with diethyl ether followed by extraction with cupferron in chloroform. From the aqueous phase Co and Zn were extracted using α-nitroso-β-naphthol in chloroform and 2-thenoyltrifluoroacetone in isobutylmethyl ketone, respectively. From another aliquot, Se was first complexed with o-phenylenediamine and extracted in benzene. Later Sb was extracted using KI and 4-(2-pyridylazo)-resorcinol (PAR) in benzene. The method yields reasonably accurate data for monitoring of trace elements in biomedical and environmental specimens.
