The toxic metals appear to use the transport pathways that exist for biologically essential metals. In this regard interactions between the toxic and essential metals are possible. This report summarizes recent findings on the transport of cadmium in rat hepatocytes and renal cortical epithelial cells in the presence or absence of certain essential metals. The transport of cadmium in hepatocyte...

Chlorella vulgaris was tested to assess their toxicities in freshwater contaminated by the metal compounds of copper (Cu) and cadmium (Cd), both singly and combined. Exposure to 0.5 and 1.5 M Cu or 1.0 and 2.0 M Cd alone significantly decreased algal growth and chlorophyll content and increased reactive oxygen species (ROS) content. Two-way ANOVA analysis shows that the combination of these two...

We examined changes in profiles of isoflavonoids in roots of lupine (Lupinus luteus L. cv. Juno) seedlings in response to treatment with two heavy metals: cadmium (at 10 mg/l) and lead (at 150 mg/l). Overall, 21 flavonoid conjugates were identified in root extracts, some of them with up to six positional isomers. The total amount of all isoflavonoids increased by about 15 % in cadmium-treated p...

Three potent tumor promoters of different classes, 12-O-tetradecanoylphorbol-13-acetate, dihydroteleocidin B, and aplysiatoxin, and two moderate tumor promoters, mezerein and debromoaplysiatoxin, enhanced the frequency of appearance of cadmium-resistant Chinese hamster lung cells when the cells were exposed to cytotoxic levels of CdCl2. With these compounds, the activity to induce cadmium-resis...

In three separate sets of studies, the effects of ureteral ligation and coadministration of cadmium with cysteine or glutathione (GSH) (in either a 4:1 or 2:1 ratio of thiol to cadmium) on the renal disposition of cadmium were assessed in rats 1 h after the administration of cadmium. In all experiments, co-administration of cadmium with either cysteine or GSH caused the renal accumulation of ca...

Environmental pollutants have hazardous impact on living organism present on this planet. Environmental pollutants give bad impact on the health of livestock as well as human beings and have been categorized as heavy metals, pesticides etc. Cadmium and its compounds are most common environmental toxicants with potential for bioaccumulation and persistence in the body, and produce versatile biot...

A new ketone Isonitroso phenyl 2 propanone (HINP2P) has been synthesized by the reaction of Benzyl magnesium chloride with cadmium chloride and acetyl chloride. On subsequent treatment of Phenyl 2 propanone with namyl nitrite gives Isonitroso Phenyl 2 Propanone. The structure of these compounds has been confirmed by physiochemical and spectral data. A preliminary screening of these compounds fo...

Wurtzite CdxZn1 xO epilayers with cadmium concentrations ranging from x = 0.02 to 0.30 were investigated using photoluminescence, transmission/reflection spectroscopy, and atomic force microscopy. The CdxZn1 xO photoluminescence peak was found to shift through the visible region from 421 (2.95 eV) to 619 nm (2.0 eV) as the cadmium concentration was increased from 2% to 30%. An additional broad ...

Cadmium compounds such as cadmium sulfate are used in batteries, pigments and in semiconductor industry. Commercially available cadmium sulfate was purchased and used for the crystal growth. The sample in salt form was dissolved in double distilled water and the saturated solution was prepared. Nearly 38 grams/50 ml are necessary to prepare the saturated solution and the solution was stirred we...

A sediment microbial fuel cell (SMFC) is a type of microbial fuel cell (MFC) that has recently attracted significantly attentions due to its unique property of removing organic and inorganic compounds from sediments. In this study the experiments were carried out in a dual-chamber SMFC with external resistances 30 kΩ-50 Ω. The SMFC was produced power about 630 mV with maximum power density 40 m...
