The oligoelements

Ion-induced bias in Ag2S luminescent nanothermometers

“…44 Other oligo-element metals ( i.e. trace elements that are found in smaller quantities in the body but are necessary for humans) 45 include Fe 2+/3+ , Cu 2+ , Zn 2+ , and Mn 2+ . 46 Among the different transition metal, iron is the most prevalent one in the body, in both oxidation states Fe 2+/3+ , 43 with serum free iron concentration in concentrations between 10–30 μM.…”

Percutaneous metals absorption following exposure to road dust powder

“…Concerning the present study, since Cd and V showed lower solubility profiles in synthetic sweat solutions as a function of their content in the road dust, they were not considered for the absorption test. In addition, even though Mn and Zn were higher soluble in synthetic sweat solution, they are oligoelements essential and beneficial to living beings involved in several metabolic, enzymatic and immunological processes (Carvalho et al, 2015), so they were discarded for the skin permeation test. Moreover, the three skin sensitisers (Co, Cr, Ni) have a similar dissolution behavior in both synthetic sweat solutions (Figs.…”

Ecotoxicity of Binary Mixtures of ILs and Inorganic Salts of Electrochemical Interest

“…Indeed, these cations play different bene cial functions in cells, since they are oligoelements, i.e. metal or metalloids ions that have an important roles as, for example, constituents of cell tissues or as catalyzers of chemical reactions of the cell metabolism (Carvalho et al 2015).…”
