Abstract This study was designed to examine the effects of a diet contaminated by environmental cadmium on organ/body weight ratio and selected toxicological indices. It was also designed to permit a comparative analysis of the effects of the diet contaminated by environmental cadmium and that of cadmium supplemented diet based on the same parameters. Our results show that even though the cadmium content of the environmental cadmium contaminated diet was 300% less than that of the cadmium supplemented diet, the former caused statistically significant changes in Superoxide dismutase (SOD) activity (P < 0.025), Na+/K+ ATPase activity (P < 0.005) and Malondialdehyde (MDA) level (P < 0.025) when values at the end of 1 month exposure were compared to the values at the end of 3 months exposure. These parameters were altered in the same manner by the cadmium content of the supplemented diet in addition to significant reduction in liver/body weight ratio(P < 0.005) within the exposure periods examined. By virtue of the very close nature of the values of these parameters in rats exposed to the two different diets, it appears that the background cadmium (cadmium from the environment) content of the diets is largely responsible for the observed changes, except in the case of liver/body weight ratio.
