Metal cation competition for Cd uptake in Xenopus oocytes. Non-labeled Cd was spiked with 109CdCl2 to make a final Cd concentration of 0.25 μM; the competing metal cations at concentrations of 0, 0.75, 2.5 or 7.5 μM were added at the same time as the Cd, and the oocytes were incubated at 20°C for 60 min, following which Cd accumulation was determined. *P <0.001. **P < 0.01).
