Cadmium

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 recovered from spent nickelcadmium batteries. First discovered in Germany in 1817, cadmium found early use as a pigment because of its ...

Cadmium Toxicity Article

Cadmium Toxicity Article

Aug 27, 2021 · Cadmium toxicity usually occurs after occupational, environmental, or hobby work exposure. Environmental exposures can occur from contamination in the surrounding soil with the metal, and then the resultant food grown there is consumed. This type of contamination can occur in areas where mining or refining of ores takes place.

Toxic Metals

Toxic Metals

Toxic metals, including "heavy metals," are individual metals and metal compounds that negatively affect people's health. Some toxic, semimetallic elements, including arsenic and selenium, are discussed in this page. In very small amounts, many of these metals are necessary to support life. However, in larger amounts, they become toxic.
