Cobalt poisoning is intoxication caused by excessive levels of cobalt in the body. Cobalt is an essential element for health in animals in minute amounts as a component of vitamin B 12. A deficiency of cobalt, which is very rare, is also potentially lethal, leading to pernicious anemia. [1]
In humans most cobalt is found in Vitamin B12.A cobalt atom is visible in the center in this diagram. Cobalt is essential to the metabolism of all animals.It is a key constituent of cobalamin, also known as vitamin B 12, the primary biological reservoir of cobalt as an ultratrace element.
[177] [176] The "coast disease" of sheep in the coastal sand dunes of South Australia in the 1930s was found to originate in nutritional deficiencies of the trace elements, cobalt and copper. The cobalt deficiency was overcome by the development of "cobalt bullets", dense pellets of cobalt oxide mixed with clay given orally, which then was ...

selenium deficiency / selenosis: Cobalt: trace NE; NE: Cobalt is available for use by animals only after having been processed into complex molecules (e.g., vitamin B 12) by bacteria. Humans contain only milligrams of cobalt in these cofactors. A deficiency of cobalt leads to pernicious anemia.
Trace metals within the human body include iron, lithium, zinc, copper, chromium, nickel, cobalt, vanadium, molybdenum, manganese and others. [1] [2] [3] Some of the trace metals are needed by living organisms to function properly and are depleted through the expenditure of energy by various metabolic processes of living organisms.
Experiments by Marston confirmed Dick Thomas's hypothesis that a cobalt deficiency was the primary cause of coast disease in sheep. He subsequently oversaw the successful introduction of cobalt supplements. [6] The New Zealand bacteriologist, Sydney Josland, undertook postgraduate training under the direction of Marston at CSIRO in Adelaide in ...
