Deborah J. Pain, Andrew Meharg, Gillian Sinclair, Nicola Powell, Jill Finnie, Robert Williams, and Geoff Hilton "Levels of Cadmium and Zinc in Soil and Plants Following the Toxic Spill from a Pyrite Mine, Aznalcollar, Spain," AMBIO: A Journal of the Human Environment 32(1), 5257, (1 February 2003).
With age the accumulation of cadmium in the body increases. When excessive amounts of Cd 2+ are present in the body, it replaces Zn 2+ at key enzyme sites. Lead: The important sources of lead for biological systems are mining, smelting, winning of metals, automobiles, etc. In urban areas, citizens are exposed to it through emission of vehicles and food.
Former smokers had cadmium and zinc concentrations that did not exceed the average concentrations for nonsmokers, indicating that hair cadmium and zinc levels reflect exposure or intake rather than cumula tive body burden.
Cadmium is produced mainly as a byproduct of mining, smelting and refining of zinc and, to a lesser degree, as a byproduct of lead and copper production. It is therefore primarily produced in relation to zinc production rather than direct cadmium demand. Global cadmium production almost .
Uptake and elimination kinetics of zinc and cadmium were studied in the oligochaetes Enchytraeus albidus and Eisenia fetida. Even at the highest exposure concentrations where E. fetida survived, the internal zinc concentration was still regulated to a constant level. Enchytraeus albidus could not regulate the internal zinc concentration as well, and the body burden increased after exposure to ...

Metal mining activities can cause a variety of soil contamination problems including the deposition of sediments having high concentrations of heavy metals on alluvial soils.
lead (Pb), zinc (Zn), and cadmium (Cd) in streams draining a Pbmining district in southeast Missouri. Samples of plant biomass (detritus, periphyton, and filamentous algae), invertebrates (snails, crayfish, and riffle benthos), and two taxa of fish were collected from seven sites closest to mining areas (mining

Zinc ores are obtained by many mining techniques, ranging from openpit mining to the normal underground methods. The most common underground method of ore extraction is cutandfill stopping, in which tunnels are dug to moderate depths, branching away from the mine holes.
Zinctocadmium ratios in typical zinc ores range from 200:1 to 400:1. Sphalerite (ZnS), the most economically significant zinc mineral, commonly contains minor amounts of other elements; cadmium, which shares certain similar chemical properties with zinc, .

Evaluation of the toxic effects of lead and cadmium in subjects in polluted work environment is mainly based on the concentrations of those toxic metals in hair. Hair can accumulate not only toxic metals such as lead and cadmium but also essential metals like zinc, manganese and iron can be .
In its elemental form, cadmium is a soft, silverwhite metal. It is not usually present in the environment as a pure metal, but is most often found in zinc, lead, and copper ores. Cadmium is not an element that is used by the body, and it is toxic. It mainly affects kidneys and bones. It is also a carcinogen by inhalation.

Lead, zinc, and cadmium were determined in a range of tissues from wild populations of bank voles (Clethrionomys glareolus) trapped on an abandoned metalliferous mine site and a reference site. Estimated dietary intakes indicated that animals were exposed to elevated levels of all three metals at the mine site, and this was generally reflected in metal residues in body tissues.
A survey of extractable copper, lead, zinc and cadmium in Northern Ireland's top soils was carried out to see if the trace element concentrations could be related to the parent material of the soils and to the influence of human activity.

In addition, the correlations between demonstrated toxicities of various compounds of lead, zinc, and cadmium in alkaline waters and simul
Treatment removes more than 90% of cadmium and more than 99% of zinc from the mine drainage. Average cadmium and zinc concentrations at the untreated mine discharge were 59 μg/L cadmium and 123,000 μg/L zinc. The treated water has cadmium and zinc .
