摘要：

The effect of lanthanum (La3+) on Na+ and Cl- fluxes and on gill potentials was investigated in the goldfish. C. auratus. Initially La3+ caused larger increases in both influx and efflux but after 15 min these decreased with influx returning to near normal levels while effluxes remained elevated, leading to a significant net loss of ions. Both La3+ and Ca2+ influenced gill potentials in an identical way. Possible physiological effects of La3+ on gill ion exchange mechanisms are discussed.
