The concentrations of zinc, copper, iron, nickel, cadmium, lead, manganese, sodium and chloride in the sweat of six males and three females were determined after collections utilizing a total body washdown technique. From our results, sweat appears to be an important excretory pathway for zinc and copper. The mean concentrations of nickel and cadmium in sweat were higher than those reported for...

OBJECTIVE Trace elements such as zinc and copper have physiological effects on neuronal excitability that may play a role in the etiology of intractable epilepsy. This topic has been rarely discussed in Iranian epileptic patients. This study with the analysis of serum zinc and copper levels of children and adolescents with intractable and controlled epilepsy may identifies the potential role of...

According to the publication by US Minerals Survey in 1999, the total reserve of manganese ore in the world is 0.66 billion tons. See Table 1.

pollution of agricultural lands is a widespread problem in mine regions. the transport of the pollutants through the food chain, causes their accumulation s in tissues of plants and animals which endangers their health. this study aimed to measure the concentrations of heavy metals (lead, copper, zinc and manganese) in wheat roots of darreh zaresh villages which might be used for future environ...

BackgroundMany studies reported that copper, zinc and magnesium play important roles in the pathogenesis and development of neonatal hyperbilirubinemia. Exchange transfusion and intensive phototherapy are known two modalities of therapy for severe neonatal hyper bilirubinemia, but the effect of them on those trace elements is unknown.Materials and MethodsCopper, Zinc and Magnesium serum levels ...

The heterogeneity and local distribution of elements are established as a result the study nonferrous metals composition domestic wastes processing concentrate containing 20–40% copper, 40–50% brass, 20–28% zinc up to 1% aluminium. Metals mainly concentrated in granules three types: zinc-based, copper-based copper–zinc alloy, i.e., brass. phase these granule types their structure determined. Zi...

This study was undertaken in order to determine heavy metal contents in twelve (n = 12) henna brands and eleven (n = 11) kohl products. An analytical test was performed for Pb, Cd, Cu, and Zn in henna and kohl products using atomic absorption spectrophotometery. The overall mean concentrations of heavy metals in henna varied between 1.2 and 8.9 μg g(-1) for Pb; 0.8 and 18.6 μg g(-1) for Cd; 0.5...

After initial promotion of copper excretion with D-penicillamine, the effect of oral zinc sulphate (3 X 150 mg/day, loading dose; 3 X 100 mg/day, maintenance dose) in two children with clinically stable Wilson's disease was evaluated after completion of three years' treatment. The course, judged by clinical, biochemical, and histological parameters was satisfactory in both. The urinary copper c...
