The content of trace elements (Cu, Cr, Ni, Pb, and Zn) in hair and skin of silver fox (Vulpes vulpes) and arctic fox (Alopex lagopus) were determined. The content of elements were determined using inductively coupled plasma atomic emission spectrometry (ICP-OES). Samples of animal hair and skin were collected from two farms located in mid-western Poland: farm A, situated in a rural area and far...

The article contains computational data of electronic structure and crystal stability of two sigma-phases, namely Fe-Cr-Co and Fe-Cr-Ni, using the Korringa-Kohn-Rostoker method (KKR) for electronic band structure calculations. Total energy values, ET , calculated for the number of ordered unit cells with various atomic concentrations and sublattice occupancies are reported. In parallel, obtaine...

Levels of selected metals Na, Ca, Mg, K, Fe, Mn, Cr, Co, Ni, Cd, Pb and Mn were estimated by flame atomic absorption spectrophotometry in groundwater samples from Kasur, a significant industrial city of Pakistan. Salient mean concentration levels were recorded for: Na (211 mg/l), Ca (187 mg/l), Mg (122 mg/l), K (87.7 mg/l), Fe (2.57 mg/l) and Cr (2.12 mg/l). Overall, the decreasing metal concen...

the reaction of an equivalent of 2- mercaptoethyl ammonium chloride with an equivalent of 2,6-diformyl -4- methyl phenol produced monoamine which was reacted with half equivalent of 1,2-diamine ethane to produce ethylene-bis-6-(2-mercapto-ethyl-imine)-methyl -4- methyl phenol [h4l]. the ligand was reacted with metal ions[cr(iii), mn(ii), fe(ii), co(ii), ni(ii), cu(ii), zn(ii), cd(ii), and hg(ii...

Este estudo teve como principal objetivo avaliar o efeito da radiação solar sobre a capacidade de complexação das substâncias húmicas aquáticas (AHS) com as espécies metálicas Al, Cr, CrO4 2e Ni. Microcosmos foram montados com AHS extraídas do Rio Preto com concentração de 5,0 mg L de carbono orgânico dissolvido e diferentes concentrações de metais, sendo expostos à radiação solar in situ. As c...

Microelements concentrations of Al, Co, Cr, Li, Mo, Ni, Sb and Sr were determined in the milk of Croatian Coldblood mares by inductively coupled plasma-optical emission spectrometry. The total mean element contents in mares milk were (mg/kg): Al<10, Co<10, Cr 26.7, Li 4.35, Mo 11.0, Ni<10, Sb 70.1 and Sr 467. Variation of Li, Sb and Sr concentrations were found throughout the lactation stages (...

The present study analyzed 5785 vegetables for concentrations of As, Cd, Cr, Pb, Ni and Hg, and estimated the health risk to local consumers by deterministic (point estimates) approaches. Levels of elements varied in different vegetables. Average levels of As, Cd, Cr, Ni, Hg and Pb were 0.013, 0.017, 0.057, 0.002, 0.094 and 0.034 mg/kg (fresh weight), respectively. The samples with 0.25% for Cd...

Soft magnetic properties of Fe-Co-Ni-Al-Cr-Si thin films were studied. As-deposited Fe-Co-Ni-Al-Cr-Si nano-grained thin films showing no magnetic anisotropy were subjected to field-annealing at different temperatures to induce magnetic anisotropy. Optimized magnetic and electrical properties of Fe-Co-Ni-Al-Cr-Si films annealed at 200 ◦C are saturation magnetization 9.13 × 105 A/m, coercivity 79...

The concentrations of heavy metals (mg/g) Pb, Ni, Cu, Cr, Fe, Co, Cd, and Hg in the water and sediments of river Ijana Warri, were determined in order to assess the impact of petroleum-processing activities on the river and the surrounding environment. The data showed that the levels of these metals ranged between 0.15-1.18 and 0.10-0.48 in sediment and water respectively. The heavy metals conc...

In the municipality of Bor (Eastern Serbia), which is known for its production of copper from sulphide ores, soil was sampled in urban, rural and background area. The content of metals (Pb, Cu, Cd, Zn, Ni, Cr) and metalloids (As, Sb, Se, Te) in the soil was determined. The highest concentrations of the analyzed elements and frequent exceedance of the limit values were observed in soil samples f...
