Cadmium is associated with industrial processes such as metal plating and the production of nickel-cadmium batteries, pigments, plastics and other synthetics. Cadmium is a potential environmental hazard. A cost effective technologies are needed to remove cadmium from the contaminated soil-water environment. Phytoremediation is a novel, cost effective and eco-friendly ‘green’ remediation technol...

PURPOSE Cadmium is a human lung carcinogen and possesses estrogen-like activity. This combination of carcinogenic and estrogenic activity makes cadmium a contaminant of high concern for hormone-related cancers. Diet and smoking are the main sources of cadmium exposure. The aim of this study was to investigate the association between dietary cadmium intake and risk of breast, endometrial and ova...

Post-mortem examinations of workers who died of cadmium poisoning after exposure to cadmium oxide fume have been reported by Baader (1951), Lane and Campbell (1954), and Bonnell (1955). Friberg (1950) and Friberg and Nystr6m (1952) reported similar examinations of workmen subjected to cadmium oxide dust. As part of a study of cadmium intoxication it was important to establish the distribution o...

Uptake of cadmium into molar enamel and dentin from rats receiving cadmium in their drinking water was markedly elevated and proportional to the amount of cadmium in the drinking water. Post-developmental cadmium did not influence caries development or alter the cariostatic effectiveness of fluoridated drinking water. The data indicate that the absolute concentration of cadmium in teeth is not ...

OBJECTIVES To investigate the effects of lead and cadmium on the metabolic pathway of vitamin D3. METHODS Blood and urinary cadmium and urinary total proteins were measured in 59 smelter workers occupationally exposed to lead and cadmium. In 19 of these workers, the plasma vitamin D3 metabolites, (25-hydroxycholecalciferol (25 OHD3), 24R, 25-dihydroxycholecalciferol (24R,25(OH)2D3) and 1 alph...

In workers chronically exposed to cadmium and without signs of renal insufficiency, plasma proteins with molecular weight ranging from 11,800 to 450,000 are excreted in greater amount in urine. Increased urinary excretion of low and high molecular weight proteins can occur independently. Because of its greater stability in urine and provided a sensitive immunological technique is used, the dete...

Synonyms, trade names and molecular formulae for cadmium, cadmium-copper alloy and some cadmium compounds are presented in Thble 1. The cadmium compounds shown are those for which data on carcinogenicity or mutagenicity were available or which are commercially important compounds. It is not an exhaustive list and does not necessarily include all of the most commercially important cadmium-contai...

Greenhouse pot culture studies were conducted to evaluate the bioremediation potential of spinach for removal of cadmium. The results indicated that spinach was able to take up cadmium in substantial quantity in the shoot. There were no visual cadmium toxicity effects on spinach and no significant reduction in the dry matter yield up to 20 μg g cadmium. Significant growth retardation of fenugre...
