Iron Deposition from Aluminosilicate Containing Trace Amount of Iron Oxide by Borate‐Enhanced Hydrogen ReductionAluminosilicate containing 0.50wt% of iron oxide as impurity yields metallic iron deposit by heating with sodium borate (3Na2O·B2O3) in H2 at 950°C, while it remains unchanged by ...
Important physiological functions in human metabolism are known for nine trace elements: selenium, zinc, copper, manganese, chromium, iron, molybdenum, iodine and fluoride. Lack of, or an insufficient supply of, these trace elements in nutrition therapy over a prolonged period is associated with ...
The crustal average value of different metals was derived from Taylor21. Iron was selected as the benchmark metal because of its prevalence in the upper crust and strong immobility. After the measurement, enrichment levels in soils were categorized following the class mentioned by Barbieri22. ...
It has been shown that copper oxide nanoparticles (CuO NPs) induce pulmonary toxicity after acute or sub-acute inhalation exposures. However, little is known about the biodistribution and elimination kinetics of inhaled CuO NPs from the respiratory tract
and potentially have adverse effects on the kidneys and spleen as there were significant changes in the weights of these organs; increase in the kidneys and decrease in the spleen. Furthermore, concentrations of selenium in kidneys and iron in spleen were decreased, pointing to disruption of trac...
Pb exposure is particularly harmful to the developing brains of children and can cause cognitive impairment, learning difficulties and behavioural problems [31]. Excessive iron accumulation in the body can result in a condition called hemochromatosis, leading to liver damage, diabetes, heart problems, ...
elevated Se concentrations appear in soils rich in iron compounds and organic matter in saline soils. The geochemical properties of this element will be present in the given area. Selenides and selenium sulphides occur mainly in acidic, oil-rich soils with a high content of organic matter. On...
, copper, lead, mercury, uranium); (4) renal tubular dysfunction without associated structural damage (lithium); (5) chronic tubulointerstitial disease without associated tubular dysfunction (silicon), and (6) excess metal deposition without apparent functional or structural changes (silver, iron). ...
A dog’s major and trace element status can be assessed from various loci such as hair and blood. Hair analysis provides a reading of elemental deposition in the cells and interstitial spaces of the hair over a 2-3-month period, and thus gives a long-term assessment of element status or...
These metals are primarily delivered to soils via atmospheric deposition of industrial dust originating from combustion of fossil fuel and gasoline as well as from non-ferrous metal smelting (Pacyna and Pacyna 2001). On a global basis, combustion of gasoline releases 74% of anthropogenic Pb and ...
