distribution and mobility of nine mineral elements (k, ca, na, mg, fe, zn, cu, se, and cr) in cultured gentiana rigescens and its root zone soil were determined by atomic absorption spectroscopy. g. rigescens materials were planted under tea and white papaya trees in yun county and yongde of lincang area in yunnan province of china. the results showed that g. rigescens and its soil were high in...

The asymmetric unit of the title compound, {[Cu(2)Fe(CN)(6)(C(2)H(8)N(2))(4)]·4.5H(2)O}(n), consists of two [Cu(C(2)H(8)N(2))(2)](2+) cations, one [Fe(CN)(6)](4-) anion, four water mol-ecules and a half water mol-ecule that lies on a twofold rotation axis. The Fe(II) atom is coordinated by six C atoms from three terminal and three doubly bridging CN(-) ligands. The bridging CN(-) ligands connec...

The concentrations of some metals (Cu, Zn, Fe, Pb) in human placentas at term in two populations living in polluted (Krakow, n = 10) and non-polluted (Bieszczady, n = 13) areas were investigated by means of graphite furnace--or flame atomic absorption spectrometry (GF-AAS or F-AAS). The concentrations of Cu, Fe and Pb were higher in Krakow vs. Bieszczady, while Zn concentration was lower, but t...

Background: Unsafe food consumption is a severe problem because of heavy metal contamination, which is caused by director indirect activities of industries. The present study was conducted to assess the risk of human health by Heavy metals (Cu, Co, Fe, Zn and Mn) through the intake of vegetables and fishes obtained from the area adjacent to the Hazaribag tannery campus, Dhaka, Bangladesh. Resul...

Emerging contaminant ciprofloxacin (CIP) has been frequently detected in soils. Its interactions with metals in soils remain largely unknown. We examined the effects of metal cations Cu and Ca and surface Fe/Al coating on CIP sorption by preloading Cu and Ca onto sand surface or mixing them with CIP in solution. Batch experiments with sand before and after removing Fe/Al coating on surface (coa...

Extracellular superoxide was detected in cultures of monkey and human arterial smooth muscle cells as indicated by superoxide dismutase inhibitable reduction of cytochrome c. Superoxide production by these cells in the presence of Fe or Cu resulted in modification of low density lipoprotein (LDL). The degree of LDL modification was directly proportional to the rate of superoxide production by c...

Solute clustering and partitioning behavior in the early crystallization stage of an Fe73.5Si13.5B9Nb3Cu1 amorphous alloy have been studied by employing a three dimensional atom probe (3DAP) and a high resolution electron microscope (HREM). 3DAP results have clearly shown that Cu atom clusters are present in the amorphous state after annealing below the crystallization temperature. The density ...

Concentrations of selected trace minerals (Cu, Fe, Zn, Mn, Co, Se) were determined from annual cool-season grass pasture forages over four consecutive winter-spring grazing seasons (2001-2005). Twice monthly forage samples were taken from eight experimental pastures used in beef cattle grazing trials. Two, 2-yr experiments were conducted; animal and pasture data were reported previously. Each e...

Blood selenium and trace minerals play an important role in animal's health and production. The aims of this study were to determine selenium effect on blood glutathione peroxidase (GPX) activity, trace minerals and weight gain in lambs. Twelve female Makuei breed were studied for 63 days in groups of control, nanoselenium (NanoSe) and sodium selenite (NaSe). Mean concentrations of GPX, Cu and ...

The smokeless powders in 22 kinds of ammunitions seized from one of the Japanese gang groups were analyzed by scanning electron microscopy/energy dispersive X-ray microanalysis (SEM/EDX). Copper(Cu), sulfur(S), potassium(K), silicon(Si), aluminum(Al), calcium(Ca), iron(Fe), chlorine(Cl), and barium(Ba) were detected. Cu was found in all samples. One sample contained a high amount of Ba. One par...
