INTRODUCTION Accumulation of trace elements occurs in conditions of decreased kidney function. In some conditions, increased trace elements can have toxic features. On the other hand, studies are showing that concentration of some trace elements could be decreased in ERSD patients as well. The most important factor affecting trace element concentration in ERSD patients is the degree of renal fa...

Trace elements diffuse negligible distances through the pristine crystal lattice in minerals: this is a fundamental assumption when using them to decipher geological processes. For example, the reliable use of the mineral zircon (ZrSiO4) as a U-Th-Pb geochronometer and trace element monitor requires minimal radiogenic isotope and trace element mobility. Here, using atom probe tomography, we doc...

Trace elements (TEs) are vital for the operation of metabolic pathways that promote growth and structural integrity. Paddy soils are often prone to TE limitation due to intensive cultivation and irrigation practices. Apart from this, rice paddies are potentially contaminated with transition metals such as Cd, which are often referred to as toxic TEs. Deficiency of TEs in the soil not only delay...

1. Energy, protein, zinc, copper, manganese, selenium and dietary fibre intakes of 100 pre-menopausal women (mean age 30.0 +/- 6.1 years) from a university community, and consuming self-selected diets, were calculated using 3 d dietary records and food composition values. Subjects also collected a 24 h food composite during the 3 d record period for analysis of Zn, Cu and Mn by atomic absorptio...

SOIL ASSOCIATIONS The selenium content of most soils ranges from 0.1 to 2 parts per million. But in general soil selenium content by itself is not a good measure for the potential for occurrence of selenium deficiency in livestock grazing or consuming forages produced from it. Soil pH has a marked effect on the form of selenium present and its availability to the plant. In alkaline, well-aerate...

We investigate the coupling between H, minor, trace, and ultra-trace element incorporations in 17 olivines from ten different locations covering various petrological origins: magmatic, hydrothermal, mantle-derived context. Concentrations major are determined by micro X-ray fluorescence. Minor, elements laser ablation inductively coupled plasma mass spectrometry. Hydrogen concentrations quantifi...

determination of trace elements in food is of great importance, as some of them have nutritional significance, whilst others are toxic. long-term exposure to low levels of toxic metals could be important, especially in relation to children. differential pulse anodic stripping voltammetry (dpasv) is applied to simultaneous determination of lead, cadmium, copper and zinc in dry ash infant formula...

Collecting rain for trace elemental analyses can be a difficult task. In Australia, most sampling of atmospheric deposition so far has been concerned with gauging the major element chemistry of atmospheric deposition to the Australian continent. Very little work has been conducted on the trace element chemistry of atmospheric deposition in the Australian landscape and, therefore, collector desi...
