Trace element analyses was carried out using Atomic Absorption Spectrophotometer and XRF on a small collection of bones and teeth from horse and human bone samples to check the ratio of strontium and calcium and other elements like zinc and copper. Interestingly the copper representation in humans is much higher compared to that of Sr/Ca. This shows that their diet consisted mainly of animal me...

Apart from the breast milk, infant formula and baby weaning food have a special role in infant diet. Infants and young children are very susceptible to amount of trace elements. Copper and zinc are two elements that add in infant food. Lead and cadmium are heavy metals that enter to food chain unavoidably. DPASV is a benefit and applicable method for measurement of trace elements in food produc...

abstract soil contamination with heavy metals is a serious problem in all over the world. soils are contaminated by many different sources of heavy metals. currently different methods are used by researchers for identifying heavy metal contamination. assessing soil metal toxicity with bacterial bioluminescence is one of the new techniques. in this study, different concentrations of zinc and cop...

The effectiveness of 1,2-dimethyl-3-hydroxypyrid-4-one (Ll) in increasing iron excretion in iron-loaded patients improved the propsects for replacing desferrioxamine (DF) with an oral chelating drug.’,’ L1 belongs to a new group of iron chelators, the a-ketohydroxypyridines (KHP); which are cheap to p ~ e p a r e ~ . ~ and orally active. Recently, a detailed article by Porter et al.’ on in vivo...

Increased environmental pollution has necessitated the need for eco-friendly clean-up strategies. Filamentous fungal species from gold and gemstone mine site soils were isolated, identified and assessed for their tolerance to varied heavy metal concentrations of cadmium (Cd), copper (Cu), lead (Pb), arsenic (As) and iron (Fe). The identities of the fungal strains were determined based on the in...

This study was conducted on 25 animals randomly selected from a herd with 40 feedlot cattle, which had poor growth, rough hair coat, and change in the colour of the hair coat. Blood samples were collected from the vena jugularis into the tubes containing Na2EDTA for the determination of plasma copper concentration and blood profile. Feed samples were also tested for copper, zinc, and molybdenum...

Rhesus monkeys were fed a diet marginally deficient in zinc (4 ppm zinc) throughout pregnancy and were monitored for changes in hematological, biochemical, and immunological parameters. This dietary zinc level was chosen because it did not produce an overt deficiency syndrome when fed for 10 wk to nonpregnant monkeys. Deprived animals were compared to control groups fed a zinc replete (100 ppm)...

A method for the speciation of zinc and copper binding with proteins in human serum was explored by chelating resin (Chelex-100) pre-treatment and inductively coupled plasma mass spectrometry (ICP-MS). It was shown by a SEC (size-exclusion chromatography)-ICP-MS system that albumin-zinc and albumin-copper (loosely-bound species) could be selectively removed from serum by adsorption on the Chele...
