27 lut 2017 · Herbivores store most Rb whereas carnivores and omnivores accumulate significantly less Rb. The analysis of 137 foodstuffs and beverages in 15-fold repetition showed that the starch-and sugar-rich cereals, pasta, bread and confectionary are poor in Rb (1 mg/kg dry mater (DM)). Fruit and vegetables accumulate between 5 and >60 mg Rb/kg (asparagus).
The scope of this entry covers the applications of rubidium isotopes in biological research and medical diagnostics. Research applications are mainly focused on animal and human studies of potassium ions replacement with rubidium ions (Rb + ) and use of Rb + as a tracer of K + transport routes.
