“…Cobalt is important for living species as a constituent of complex vitamin B 12 , which is present in human and animal cells. [1][2][3][4] Deficiency of vitamin B 12 causes different types of diseases, including neurological damage and anemia. 2 Cobalt is also an essential micronutrient that contributes to the growth of plant and animals.…”

“…The AdCSV determination usually involves the formation of metal complexes and an accumulation on the working electrodes and then the subsequent measurement of the reduction or oxidation peak of the accumulated complex of the electrode surface. Various complex agents have been used to determine the cobalt including dimethylglyoxime (DMG) [9][10][11], nioxime [12][13][14][15], α-furil dioxime [2], and pyrogallol red [16]. Among them, DMG and nioxime are the most popular complex agents because they offer the higher selectivity, the better shape of voltammetric signal, and the more excellent sensitivity.…”

“…Alguns autores têm apontado que em quantidades excessivas, o cobalto pode tornar-se perigoso para os seres humanos, causando vários tipos de doenças, como cardiopatias, vasodilatação, problemas neurológicos, alterações na tireóide e no pulmão. 32,35,34,40,42,43,44 As principais fontes de exposição de cobalto aos seres humanos são por vias respiratória, dérmica ou por meio da dieta (água e alimentos contaminados). 32,34,38,45 A absorção do cobalto pelo trato gastrointestinal e pela via respiratória é proporcional à solubilidade dos compostos de cobalto em meio biológico.…”
