Studies were conducted at the deepest location of the meromictic Piaseczno pit lake, southern Poland, which was created in abandoned sulphur opencast. Pearson correlation and PCA were used to established the relationship between the elements and physico-chemical parameters of the water, whereas discriminant test to study vertical and time differentiation of Cd, Pb, Sr, Cu, Zn, Mn, and Fe concen...

Background: Coronary artery diseases are multifactorial, and over the last several decades particular consideration and research have been devoted to investigating the imbalance of patient elemental levels. Our current study aimed to investigate the comparative distribution of Ca, Mg, Fe, Zn, Cu, Co, Mn, Cr, Cd and Pb in the blood of coronary artery disease patients and healthy subjects. Method...

This study was conducted to measure the concentrations of strontium (Sr), barium (Ba), cadmium (Cd), copper (Cu), zinc (Zn), manganese (Mn), chromium (Cr), antimony (Sb), selenium (Se), and lead (Pb) in canine liver, renal cortex, and renal medulla, and the association of these concentrations with age, gender, and occurrence of chronic kidney disease (CKD). Tissues from 50 dogs were analyzed us...

A new bipyridyl derivative 1 bearing rhodamine B as visible fluorophore was designed, synthesized and characterized as a fluorescent and colorimetric sensor for metal ions. Interaction with Cu(2+), Zn(2+), Cd(2+), Hg(+), and Hg(2+) ions was followed by UV/Vis and emission spectroscopy. Upon addition of these metal ions, different colorimetric and fluorescent responses were observed. "Off-on-off...

Surface characterization and metal ion adsorption properties of Spirulina sp. and Spirulina maxima were verified by various instrumental techniques. FTIR spectroscopy and potentiometric titration were used for qualitative and quantitative determination of metal ion-binding groups. Comparative FTIR spectra of natural and Cu(II)-treated biomass proved involvement of both phosphoryl and sulfone gr...

Utilization of treated wastewater (TWW) for agricultural purposes has grown over the past few years because limited available water resources. This study was performed to assess long-term irrigation from Wadi-Musa region on accumulation heavy metals in soil and their uptake translocation various parts olive trees. Fifteen year old trees that had been irrigated with resources since establishment...

The stability constants of the 1:1 complexes formed between methylphosphonylphosphate (MePP(3-)), CH(3)P(O)(-) (2)-O-PO3(2-), and Mg(2+), Ca(2+), Sr(2+), Ba(2+), Mn(2+), Co(2+), Ni(2+), Cu(2+), Zn(2+), or Cd(2+) (M(2+)) were determined by potentiometric pH titration in aqueous solution (25 degrees C; l = 0.1 M, NaNO(3)). Monoprotonated M(H;MePP) complexes play only a minor role. Based on previo...

Manganese (Mn) deficiency is an important plant nutritional disorder in many parts of the world. Barley (Hordeum vulgare) genotypes differ considerably in their ability to grow in soils with low Mn(2+) availability. Differential genotypic Mn efficiency can be attributed to differences in Mn(2+) uptake kinetics in the low nanomolar concentration range. However, the molecular basis for these diff...

The possibility of direct measurement of trace elements in hepatic cytosol of European chub (Squalius cephalus) by high-resolution inductively coupled plasma mass spectrometry (HR ICP-MS) after cytosol dilution with Milli-Q water and subsequent acidification was investigated. Due to low detection limits of this procedure, determination of 13 elements (As, Cd, Co, Cu, Fe, Mn, Mo, Pb, Sb, Sn, Sr,...

The fertigation response of sugar mill effluent doses namely: 5%, 10%, 25%, 50%, 75% and 100% on Abelmoschus esculentus (var. IHR 31) in two different seasons, that is, rainy (Kharif) and summer (Zaid) seasons was investigated. The study revealed that fertigant had significant (P<0.01) effect on moisture content, EC, pH, Cl , OC, HCO3 , CO3 -2 , Na + , K + , Ca 2+ , Mg 2+ , Fe 2+ , TKN, NO3 2, ...
