measurement of availability and mobility of heavy metals in river sediments is required in order to understand the behavior of these metals and to prevent potential toxic hazards. leaching column experiments were conducted for four sediment samples to determine the degree of mobility and the distribution of zn, cd, ni, cu, and pb because of an application of spiked heavy metals in sediments. se...

The purpose of this study was to determine the accumulation levels ten metals (Fe, Zn, Cd, Cu, Co, Ni, Al, Mn, Pb, and Cr) in muscle tissues Actina equina indvduals. A total 120 individuals A. were collected at six different stations İskenderun Bay spring 2013. heavy found vary significantly among stations. mean concentrations Fe highest Samandağ station (105.11 ± 74.28 mg/kg) whereas lowest av...

BACKGROUND Nickel (Ni) and zinc (Zn) are trace elements present at low concentrations in agroecosystems. Nickel, however, may have toxic effects on living organisms and is often considered as a contaminant. This study reports the effect of peroral administrated Ni or a combination of Ni and Zn on femoral bone structure in rabbits. METHODS One month-old female rabbits were divided into three g...

Availability and uptake of heavy metals (Zn, Cu, Fe, Al, Cr, Ni) by mung bean grown on coal mine spoil was studied. The experiment was carried out as a pot culture experiment using garden soil and different proportion of coal mine spoil. The heavy metals were transported to roots then shoot and were found in traces in the fruits. No toxicity symptom was reported during vegetative as well as rep...

The complexation reaction between metal cations o f different valence states (Al, Bi(III), Cr(III), Fe(III); Ca, Co(II), Cu(II), Mn(II), Ni(II), Pb(II), Zn; Na) and fulvic acids is investi­ gated by the streaming current detection technique. It can be shown that the metal complexa­ tion capacity does not only depend on the nature o f the cation but also on the origin o f fulvic acids, which wer...

The USP has proposed using inductively coupled plasma (ICP) for determining heavy metals in drug articles to replace the USP <231> heavy metals test. While the current USP <231> procedure will detect Pb, Hg, Bi, As, Sb, Sn, Cd, Ag, Cu and Mo, the proposed method will test for Al, Sb, As, Be, B, Cd, Cr, Co, Cu, In, Ir, Fe, Pb, Li, Mg, Mn, Hg, Mo, Ni, Os, Pd, Pt, Rh, Rb, Ru, Se, Sr, Tl, Sn, W and...

A field experiment using a block design was set up from 1995-1999. Soil at this site is the well-drained Bungor Series, clayey, kaolinitic, isohyperthermic Typic Paleudults. The treatments for the first cycle are no sludge application, inorganic N (ammonium sulfate) at 140 kg N ha and sludge application rates at 150, 300, 450 and 600% of recommended fertilizer N rate of 140 kg N ha. No sludge w...

Some heterobimetallic ion-pair complexes of Ni(II) with Mn(II), Co(II) and , Zn (II) using 1,10-phenanthroline (phen) and 1-tert-butylimidazole-2-thione (tm) ligands were prepared by co-crystallization of Ni(II)-phen cationic complex and Cl / tm containing anionic complex in acetonitrile / methanol solvent. The [Ni(phen)3][MnCl4] (1) contains two molecule of acetonitrile and [Ni(phen)3] 2+ is h...

Copper (Cu) is the most potent catalyst for dioxin formation, but Iron (Fe), Zinc (Zn), Potassium (K) and Sodium (Na) have also been found in multiple studies to be correlated with increased dioxin/furan formation. Some studies have also indicated that Manganese (Mn), Magnesium (Mg) and Nickel (Ni) may also serve as catalysts for dioxin formation. Studies have conflicted on whether Aluminum (Al...
