What is Cadmium used for in everyday life?

By far the most important use of cadmium in the United States is in the production of nicad ( nickel -cadmium), or rechargeable, batteries. It is also used in pigments, coatings and plating, manufacture of plastic products, and alloys. An alloy is made by melting and mixing two or more metals.

What does cadmium smell like?

Cadmium does not have a definite taste or odor. Cadmium is not mined, but it is a by-product of the smelting of other metals such as zinc, lead, and copper. Cadmium is used in nickel-cadmium rechargeable batteries and for metal plating.

How does one get cadmium poisoning?

Cadmium toxicity occurs when a person breathes in high levels of cadmium from the air, or eats food or drinks water containing high levels of cadmium. Cadmium is a naturally occurring metal. It is usually present in the environment as a mineral combined with other elements like oxygen, chlorine, or sulfur.

How is Cadmium tested in the body?

The best screening and diagnostic test for chronic cadmium exposure is a 24-hour urinary cadmium level, normalized to creatinine excretion. Urinary metallothionein and β2-microglobulin excretion can be correlated with long-term cadmium exposure.

Where is cadmium most commonly found?

It is most often found in small quantities in zinc ores, such as sphalerite (ZnS). Cadmium mineral deposits are found in Colorado, Illinois, Missouri, Washington and Utah, as well as Bolivia, Guatemala, Hungary and Kazakhstan. However, almost all cadmium in use is a by-product of treating zinc, copper and lead ores.

What are the symptoms of heavy metals in the body?

What are the harmful effects of cadmium?

Cadmium and its compounds are highly toxic and exposure to this metal is known to cause cancer and targets the body’s cardiovascular, renal, gastrointestinal, neurological, reproductive, and respiratory systems.

What foods are high in cadmium?

Cadmium in food The food groups that contribute most of the dietary cadmium exposure are cereals and cereal products, vegetables, nuts and pulses, starchy roots or potatoes, and meat and meat products. Due to their high consumption of cereals, nuts, oilseeds and pulses, vegetarians have a higher dietary exposure.

Why is cadmium toxic to humans?

Inhaling cadmium-laden dust quickly leads to respiratory tract and kidney problems which can be fatal (often from kidney failure). Ingestion of any significant amount of cadmium causes immediate poisoning and damage to the liver and the kidneys. Compounds containing cadmium are also carcinogenic.

Can cadmium be absorbed through the skin?

Absorption through the skin is not a significant route of cadmium entry; only about 0.5% of cadmium is absorbed by the skin (ATSDR 1999).
