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] Exposure to cobalt metal dust is most common in the fabrication of tungsten carbide. [2]
These elements include vanadium, manganese, iron, cobalt, copper, zinc, selenium, strontium and molybdenum. [75] A deficiency of these essential metals may increase susceptibility to heavy metal poisoning. [76] Selenium is the most toxic of the heavy metals that are essential for mammals. [77]
An aspirational method of decontamination of heavy metals is phytoremediation or bioremediation, but these approaches have solved few real world problems. Toxic metals can bioaccumulate in the body and in the food chain. [5] Therefore, a common characteristic of toxic metals is the chronic nature of their toxicity.
Around 75 per cent of the world’s cobalt is mined in the DRC -- and the world cannot get enough of it. The rare, silvery metal is an essential component to every lithium-ion rechargeable battery ...
Cobalt is primarily used in lithium-ion batteries, and in the manufacture of magnetic, wear-resistant and high-strength alloys. The compounds cobalt silicate and cobalt(II) aluminate (CoAl 2 O 4, cobalt blue) give a distinctive deep blue color to glass, ceramics, inks, paints and varnishes. Cobalt occurs naturally as only one stable isotope ...
The buyers dismantled the containers, exposing themselves and others to ionizing radiation. Eighteen people, including seven children, were admitted to hospital. Ten of the adults developed acute radiation syndrome. One exposed cobalt-60 source was retrieved, but the source from the other package was still unaccounted for one year later.
