Metals are harmful pollutants because they cannot be broken down by living organisms. An excess of metal can become toxic. The in question is copper (Cu). This research aimed to determine the phytoremediation effectiveness Acorus calamus, Pistia stratiotes, and Azolla pinnata as candidates for Cu absorption. investigation employed a wholly random factorial design with two factors: plant absorbe...
Our aim to establish the metal (Pb, Cd, Cr, Cu and Zn) levels of wild mammalian scat samples deriving from sanctuaries of Western Rajasthan and compare the concentrations between Desert National Park, Jaisalmer and Gajner Wildlife sanctuary, Bikaner. Restrictions on the sampling because of Wildlife Protection Act (1972) prevents taking of samples of living tissues to analyse body burdens of con...
Abstract This study aimed to determine the optimum conditions for durian skin biomass absorb copper metal (Cu) from its solution. Determination of includes weight, pH biosorption, biosorption contact time, and initial concentration (Cu). adsorbed analyte used Atomic Absorption Spectrophotometry (AAS). In this study, was obtained local waste Parigi Regency, Central Sulawesi Province. The paramet...
Ion homeostasis plays important roles in development of metabolic diseases. In the present study, we examined the contents and distributions of 25 ions in chicken muscles following treatment with selenium (Se) deficiency for 25 days. The results revealed that in chicken muscles, the top ranked microelements were silicon (Si), iron (Fe), zinc (Zn), aluminum (Al), copper (Cu) and boron (B), showi...
Three Eu(II1) luminescent compounds were separately entrapped in a xerogel porous silica matrix and finely ground particles of it were deposited on a glass support with polyvinylacetate (PVAc) as a binder to build a thin film sensor. These 3 devices were immersed in aqueous solutions of Cu(I1) and the content of this metal was evaluated by emissionquenching experiments. The sensor containing th...

The Qaleh-Zari specularite- rich Cu-Au-Ag deposit is located 180 Km south of Birjand. Host rocks are mainly Tertiary andesites and andesitic basalts and some Jurassic shales and sandstones. Andesitic rocks from the western region of Qaleh-Zari were dated to 40.5±2 Ma. Four trends of faults and joints are identified in the mine area. The oldest is mineralized. Three major sub-parallel quartz ve...
Here, a distinct demonstration of highly sensitive and selective detection of copper (Cu(2+)) in a vastly porous cellulose acetate fibers (pCAF) has been carried out using dithiothreitol capped gold nanocluster (DTT.AuNC) as fluorescent probe. A careful optimization of all potential factors affecting the performance of the probe for effective detection of Cu(2+) were studied and the resultant s...
Dietary selenium has been implicated in the prevention of cancer and other diseases, but its safety and efficacy is dependent on the supplemented form and its metabolites. In this study, X-ray absorption spectroscopy (XAS) and X-ray fluorescence microscopy (XFM) have been used to investigate the speciation and distribution of Se and Cu in vivo. In kidneys isolated from rats fed a diet containin...
Copper (Cu) and cholesterol (Cho) are both associated with neurodegenerative illnesses in humans and animals models. We studied the effect in Wistar rats of oral supplementation with trace amounts of Cu (3 ppm) and/or Cho (2%) in drinking water for 2 months. Increased amounts of nonceruloplasmin-bound Cu were observed in plasma and brain hippocampus together with a higher concentration of cerul...
