Cadmium
Individuals and organizations have been reviewing cadmium's bioinorganic aspects for its toxicity. The most dangerous form of occupational exposure to cadmium is inhalation of fine dust and fumes, or ingestion of highly soluble cadmium compounds. Inhalation of cadmium fumes can result initially in metal fume fever, but may progress to chemical pneumonitis, pulmonary edema, anCadmium (Cd) is a very soft, silvery-white metallic element that can be cut with a knife. Cadmium has many chemical similarities to zinc and is often recovered from the primary Cadmium Mining Processing Equipment Flow Chart

Cadmium Overview Occupational Safety and Health
Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. Most of the cadmium produced today is obtained from zinc byproducts and Cadmium is emitted to soil, water, and air by non-ferrous metal mining and refining, manufacture and application of phosphate fertilizers, fossil fuel combustion, Proper disposal of cadmium-containing products. Dispose of nickel-cadmium batteries properly. Many states have laws in effect that ban the disposal of batteries as municipal waste.Cadmium Public Health Statement ATSDR Centers for Disease

The Facts on Cadmium Dartmouth Toxic Metals
In its pure form, cadmium is a silvery white, malleable metal with a bluish hue. It is found naturally in the earth’s crust and is a relatively rare metal, ranking 67th in abundance among the 90 naturally occurring elements on Earth. Cadmium is odorless and tasteless, and chemical analysis is most often required to detect its presence.The single most important use of cadmium is in the production of nickel-cadmium (“Ni-Cad”) batteries. About three quarters of the cadmium consumed annually is used to make batteries. Nickel-cadmium batteries are rechargeable and have found wide use in cellular phones, hand-held cordless power tools, cameras, portable computers, and a wide Cadmium Minerals Education Coalition

The Effects of Cadmium Toxicity PubMed
The liver and kidneys are extremely sensitive to cadmium's toxic effects. This may be due to the ability of these tissues to synthesize metallothioneins (MT), which are Cd-inducible proteins that protect the cell by tightly binding the toxic cadmium ions. The oxidative stress induced by this xenobiotic may be one of the mechanisms responsibleThis article discusses the causes of the contamination of rice with cadmium in China and considers what we know about the severity of the problem. It argues that it is misleading to extrapolate simply from levels of cadmium in soil to health risks, because the uptake of cadmium by crops and the health impacts of the metal are affected by multiple From Soil Pollution to “Cadmium Rice” to Public Health BioOne

Cadmium Toxicity: What is Cadmium? Environmental Medicine
Cadmium is an element. Its most abundant naturally-occurring isotope is non-radioactive. It is found in nature in mineral forms and is obtained for commercial uses principally from cadmium ore, called greenockite, which is commonly found in association with zinc ore. Commercial production of cadmium ore depends on the mining of zinc (ATSDR 1999).Hereby a list of commonly found by-metals in copper mining with a few of their applications: Bismuth: low melting alloys for soldering or as an additive to improve machinability. Cobalt: superalloys, batteries. Gold: jewelry, electronics, monetary uses.

Reducing cadmium inputs. Cadmium concentration in crops is related to the concentration of available Cd in the soil; therefore, it is important to reduce external inputs of Cd into agricultural soils to reduce risk of accumulation.

WEEE: Waste Electrical and Electronic Equipment Toxins
Cadmium enters soil, water, and air, and does not break down in the environment. Particles in the air can travel long distances, and cadmium binds strongly to soil particles. Cadmium products that end up in landfills lead to acid leachate that can seep into groundwater. Fish, plants, and animals can take up cadmium from the environment.Cadmium is used to make low-temperature melting alloys, such as solder and Wood’s Metal for indoor sprinkler systems. The latter is an alloy of 50%Bi, 25%Pb, 12.5% Sn, and 12.5%Cd which melts at about 160 degrees Fahrenheit, the temperature of a very hot shower.
