Fig. 5. (A) Percentage inhibition of calcium uptake in juvenile rainbow trout
exposed to control conditions (black bar) or 1 µmol l-1
lanthanum, 1 µmol l-1 cadmium or 100 µmol l-1 zinc
(white bars) in synthetically modified water (600 µmol l-1
Ca2+). (B-D) Branchial lead accumulation in juvenile rainbow trout
exposed to control conditions (black circles) or (B) a series of waterborne
lanthanum concentrations, (C) a series of waterborne cadmium concentrations,
and (D) a series of waterborne zinc concentrations. Values are means ±
1 S.E.M. (N=7 per treatment). *Significant
difference (P<0.05; two-tailed Student's t-test) from
corresponding control mean.
