  • Cadmium (Cd) Toxicity: Where is Cadmium Found? ATSDR ...

    2013-12-10  Cadmium in the Food Chain From the soil, certain plants (tobacco, rice, other cereal grains, potatoes, and other vegetables) take up cadmium more avidly than they do other heavy metals such as lead and mercury (Satarag et al. 2003). Cadmium is also found in meat, especially sweetmeats such as liver and kidney.

    Once on the ground, cadmium moves easily through soil layers and is taken up into the food chain by uptake by plants such as leafy vegetables, root crops, cereals and grains (ATSDR 1999). Cadmium concentrations in drinking water supplies are typically less than 1 microgram per liter (μg/L) or 1 part per billion (ppb) (ATSDR 1999). Groundwater seldom contains high levels of cadmium unless it ...

    OverviewApplicationsCharacteristicsHistoryOccurrenceProductionBiological role and researchEnvironment

    Cadmium is a common component of electric batteries, pigments, coatings, and electroplating. In 2009, 86% of cadmium was used in batteries, predominantly in rechargeable nickel-cadmium batteries. Nickel-cadmium cells have a nominal cell potential of 1.2 V. The cell consists of a positive nickel hydroxide electrode and a negative cadmium electrode plate separated by an alkaline electrolyte (potassium hydroxide). The European Union put a limit on cadmium in electronics in 2004 of 0.01%, with some ex
