Abstract Mine wastes are a major environmental problem of main mines activities. However, in recent years, related to the circular economy strategy, some these have been considered as secondary source raw materials. Generally, metal’s content show low concentrations and their recovery made development cheap sustainable technologies necessary. The objective present research is study potential zi...

To investigate the relationships of trace element concentrations vs hematopoiesis and iron parameters, we measured lead, copper, zinc, cadmium, and ferritin levels in 251 healthy adolescents. Concentrations of trace metals were determined by atomic absorption spectrophotometry. There were no significant gender-related differences in serum copper or serum cadmium concentrations. However, blood l...

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...

AIM The main objectives of this study were for comparing the effect of batteries and deep litter rearing systems of domesticated Japanese quail, Coturnix coturnix japonica, on the concentration levels of cadmium, copper, lead, and zinc from the quail meat and offal in Ismailia, Egypt. MATERIALS AND METHODS A total of 40 quail meat and their offal samples were randomly collected from two main ...

Abstract Purpose The increasing volumes of mine tailings that are being generated globally because the rise in metal demand, whilst ore-grades continue to decline, call for novel sustainable management options. Phytoextraction using hyperaccumulator plant species may be one such strategies deal with these large contaminated materials. However, base metals (such as zinc, lead, copper) inherently...

heavy metals found in urban air with its toxic effects have a direct impact on human health. selection of appropriate tree species and shrub refining capacity of heavy metals in urban areas can greatly reduce the toxic effects of these materials. this study aimed to identify the most suitable tree and shrub species of broadleaf evergreen, deciduous and coniferous refinement of heavy metals lead...

The geochemical behavior of zinc, lead and copper from sulfidic tailings in a mine site with potential to generate acidic drainage (pyrite (55%) and sphalerite (2%)) is reported in this paper. The mining area is divided in two zones, considering the topographic location of sampling points with respect to the tailings pile: (a) outer zone, out of the probable influence of acid mine drainage (AMD...

This study was to determine the feasibility of using potentiometric stripping analysis (PSA) to measure serum levels of copper, lead, and zinc in elderly subjects with metabolic disorders (hyperglycemia, hypertriglyceridemia, and hypercholesterolemia). Furthermore, we investigated the relationship between serum trace elements and lipid and glucose levels in these patients. There was a strong co...
