Abstract
Cadmium and copper accumulated nonuniformly in the kidney of wild brown tro ut on a longitudinal gradient as follows: the concentration in head kidney ( anterior portion of tail kidney < posterior portion(s) of tail kidney. Zi nc accumulated uniformly along the length of the kidney. Cadmium and copper accumulation in brown trout kidneys was lowest in the head kidney, where h ematopoietic tissue dominates, and greatest in posterior tail sections, whe re filtration tissues dominate. Sampling programs designed to monitor cadmi um and copper accumulation in trout kidneys should utilize the entire kidne y, including the head kidney, to create comparable data sets.
