Abstract
The cadmium contents in muscle, brain, gills, liver , intestine and testis from exposed and control animals were determined by atomic absorption spectroscopy. The experiments were planned in three series of a total of 95 fish employing the static test method of acute toxicity. Five fishes were placed in each concentrations of three sublethal concentrations (5, 15 and 25mg/l) for two acute periods (24 and 96h). The experiments were performed as 3 replicates, the Cd accumulation in different fish organs were determined. This showed that the effect of acute Cd on different organs Cd accumulation in the G. holbrooki was found to be time dependent fashion. Atomic absorption examination showed that the Cd-content in both testis and intestine increased significantly time dependent by 502%, 167%, 168%, 146%,490%,214% in muscle ,brain, liver, gills, intestine and testis , respectively at short-acute term treatment whereas for long- acute term treatment this increasing were 44%,82 %,170%,127%,350%,400% in muscle ,brain, liver, gills, intestine and testis respectively
