The role of structural factors in determining the relative efficacy of dithiocarbamates as chelating agents for the in vivo mobilization of aged cadmium deposits is examined for 23 newly synthesized compounds of this type. The critical feature in determining the efficacy of the compounds in mobilizing intracellular cadmium is the balance between hydrophobic and hydrophilic groups. This balance ...

Cadmium is a heavy metal, a well recognized environmental pollutant with numerous adverse health effects. Being widely used in industry, cadmium can affect human health through occupational and environmental exposure (Waisberg et al., 2003). The level of cadmium compounds in the environment have progressively increased as a consequence of industrial pollution which can be attributed to electrop...

Purpose: To determine whether chromium, cadmium, and lead levels in human Fingernails reflected the exposure to workplace contamination in tanneries. Approach: 49 exposed tanning workers and 33 controls were monitored for fingernail levels of chromium, cadmium, and lead by graphite furnace and hydride atomic absorption spectroscopy. Results: The mean levels of fingernail chromium, cadmium, and ...

Cadmium is a dangerous occupational and environmental toxin. It accumulates in the human organism mainly in liver and kidneys. Cadmium half-life is about 10 years, so the symptoms of cadmium intoxication may occur several years after the exposure. Until now in treating intoxication with this metal chelating compounds have been used, burdened with numerous undesirable symptoms. In our investigat...

Salts of divalent cadmium are well-known human mutagens and carcinogens. In the present work, the ability of vitamin C to modulate genotoxic effects of cadmium chloride on human lymphocytes was assessed using single cell gel electrophoresis (comet assay). Vitamin C at 20 and 100 micromol/l and cadmium at 5, 30 and 150 micromol/l significantly increased the tail moment of lymphocytes. Vitamin C ...

The syntheses and structures of five mononuclear zinc and cadmium selone complexes along with a polynuclear cadmium selone 1D chain were described. The mononuclear homoleptic zinc selone complexes were the first examples of structurally characterized zinc(ii) selone complexes. The spectral properties of the zinc and cadmium selone derivatives were investigated. Interesting structural diversity,...

Cadmium removal by living cells of the marine microalga Tetraselmis suecica was tested in cultures exposed to different cadmium concentrations (0.6, 3, 6, 15, 30 and 45 mg/l). The EC50 for growth was 7.9 mg Cd/l after six days of exposure. The cadmium removed was proportional to the concentration of this metal in the medium and it was dependent on the time of exposure; cultures with higher cadm...

according to paracelsus (1493-1541) everything from this planet is poison, only the dose makes the poison to be harmless. even the essential elements for life support are toxic for all organisms in high amounts. mercury, cadmium, metalloid arsenic and lead were responsible for poisoning and death of many humans and life forms from this planet for centuries. cadmium forms different compounds tha...

Sulphur is an essential macroelement that plays important roles in living organisms. The thiol rich sulphur compounds, such as cysteine, γ-Glu-Cys, glutathione and phytochelatins participate in the tolerance mechanisms against cadmium toxicity. Plants, algae, yeasts and most prokaryotes cover their demand for reduced sulphur by reduction of inorganic sulphate. The aim of this study was to inves...
