Abstract
Cadmium accumulation and its effect were examined in several organs of rainbow trout (Oncorynchus mykiss). Groups of 20 trouts were exposed for a three‐week period at different subacute oral doses of Cl2Cd (0.01, 0.025 and 0.05 μg Cd/mL, respectively). Cadmium uptake and storage were weekly studied in some soft tissues: kidney, liver, gills, muscle and brain. Cadmium determination was carried out using the Atomic Absorption Spectroscopy technique (AAS) with graphite furnace. After 21 days of exposure, cadmium concentrations increased significantly in all studied tissues, except in muscle and brain. The most important cadmium exposure effect was on the kidney.
