Conteúdo:  Uptake, accumulation and redention of radioactive cadmium were studied in goldfish, Carassius auratus L., as materials and Cd as radiotracer. At the 30th day after immersion, the whole body of goldfish accumulated an amout of cadmium as high as 7.5 times concentration (0.108 ppm) of the metal in surrounding water. As selected organs and tissues, liver, kidney and gill were the most radioactive components per unit weight. Retentions of radioactivity in the whole body of golfish depends on the amounts of cadmium injected. Most of the retained radioactivity concetrated in the liver, kidney, intestinal tract, fins and scales. The distribution of radioactivity in selected tissues and organs of goldfish showed different patterns in fish injected with Cd and fish exposed to the radiocadmium by immersion. Histological responses to cadmium were studied with juvenile and adult carp, Cyprinus carpio L. as materials. Pathological changes attributable to cadmium poisoning were observed not only in those organs and tissues which accumulated large quantity of cadmium such as liver, kidney, intestinal tract and gill but also in those which accumulated less quantity of the metal such as vertebrate and muscle. The injection of cadmium (intrarterially) rather than immersion, seemed to cause more serious effects to tissues and organs, especially the kidney.
