cadmium (Cd), chemical element, a metal of Group 12 (IIb, or zinc group) of the periodic table.

Why is cadmium toxic to humans?

Cadmium causes mutations and chromosomal deletions potentially (17). Its toxicity involves depletion of reduced glutathione (GSH), binds sulfhydryl groups with protein, and causes to enhance production of reactive oxygen species (ROS) such as superoxide ion, hydrogen peroxide, and hydroxyl radicals.

Can you touch cadmium?

Products containing cadmium are not harmful to touch but can be harmful if they are put in the mouth or swallowed, which can result in poisoning.

When was cadmium banned?

Cadmium has been banned in some types of plastic since 1992, and the ban has now been extended. Its use was previously allowed in rigid PVC, although PVC manufacturers have voluntarily phased out cadmium in their products.

Is cadmium still used?

Big Plus for Battery-powered and Solar Energy The most common use of cadmium is in nickel-cadmium (Ni-Cd) rechargeable batteries. They have a high energy density and long lifespan, which makes them popular for industrial uses. More recently, Jaber says, cadmium is being used in the solar energy industry.

Is cadmium a rare element?

Cadmium is extremely rare in the Earth's crust, with less than one-fifth of a gram of the metal — about one fifth of the metal in a thumbtack — in every ton of crustal material.

Which foods are high in cadmium?

Cadmium is used in many products, including batteries, pigments, metal coatings, and plastics, and it is found in cigarette smoke.

What does cadmium do to the brain?

Cadmium can cross from the blood and accumulate in the brain, causing neurotoxicity by activating various signaling pathways involved in inflammation, oxidative stress and neuronal apoptosis.

What organ does cadmium damage?

The kidney is the principal organ targeted by chronic exposure to cadmium. Cadmium nephrotoxicity may follow chronic inhalation or ingestion. Data from human studies suggest a latency period of approximately 10 years before clinical onset of renal damage, depending on intensity of exposure.

Is cadmium in coffee?

Apart from antioxidants and other bioactive compounds, coffee contains carbohydrates, lipids, nitrogen compounds, vitamins and minerals, including toxic elements such as cadmium (Cd) and lead (Pb) [12, 14, 15].

Is cadmium safe to eat?

Only a small amount of cadmium remains in the body after eating food contaminated with cadmium, but if consumed over a long period of time, cadmium can lead to kidney disease and cause bones to become weaker.
