Cobalt is widespread in the natural environment and can be formed as an effect of anthropogenic activity. This element is used in numerous industrial applications and nuclear power plants. Cobalt is an essential trace element for the human body and can occur in organic and inorganic forms. The ...
Compared with the ICRP's current model, the proposed model yields similar predictions of whole-body retention but substantially different predictions of the systemic distribution of cobalt as a function of time after uptake to blood.doi:10.1016/j.scitotenv.2007.08.054R.W. Leggett...
A Cobalt Function Cobalt is novel because there is no evidence that any organism needs the cobalt ion, either in the free form or as a simple protein complex. Cobalt in the form of a specific complex, vitamin B12 or one of the cobalamides, is essential for animals and many bacteria. Pl...

[Zimmerman, p. 4] Can cause occupational contact urticaria; [Kanerva, p. 219] "Accordingly, a TLV-TWA of 0.02 mg/m3, as Co, is recommended to minimize the potential risk of developing asthma, pulmonary function changes, and myocardial effects. The recommended TLV applies to elemental cobalt...
The oral bioavailability of inorganic cobalt compounds is a function of their water solubility and varies from 5 to 45%. In occupational settings, workers are exposed to mainly inorganic cobalt compounds by inhalation of dust. The absorption rate of inhaled cobalt also varies with the species ...
Because the lithium-ion battery slowly loses capacity as a function of both time and the total number of charge/discharge cycles, the patient will eventually experience a reduced time interval between recharge sessions. However, because rechargeable batteries can, in principle, provide unlimited energy...
