Abstract
Walleye eggs (S. vitreum) retained 5 .mu.g/g Tb after they water-hardened for 30 min in terbium dicitrate solutions containing 100-1250 .mu.g/l Tb. Tb was detected by X-ray-excited optical luminescence (XEOL) spectroscopy. Nanogram parts per gram concentrations of Tb were detected in sac fry hatched from Tb-labeled walleye eggs and remained detectable through the early juvenile stage. Walleye juveniles that had developed scales and spines (3 wk or older) contained inorganic elements such as Ca and Mg that prevented the detection of Tb. Attempts to isolate Tb from these other cations by an ion-exchange technique were not successful.This publication has 1 reference indexed in Scilit:
