Abstract

This experiment was undertaken to determine the effect of several levels of cadmium on growth and some mineral concentrations in the serum, tibia and teeth of rats. The results obtained are summarized as follows. Growth rate was significantly decreased as the feeding level of cadmium increased, especially body weight in the 40 ppm level was greatly reduced than that of initial body weight. The weight of liver was increased in 40 ppm group as a result of edema. But the weight of kidney, heart, spleen, lung and testis was not affected. The cadmium concentration of serum was higher in rats receiving 40 ppm than that of other levels, and the concentrations of iron, zinc, copper, magnesium and calcium were decreased as the cadmium content of drinking water increased. The cadmium and phosphorus contents of tibia were greatly high in the 40 ppm level, but the content of iron copper, zinc, magnesium, calcium and ash tended to be decreased with increasing level of cadmium. The cadmium concentration of teeth was predominantly high compared with that of the serum and tibia. Also, the concentration of iron, copper and zinc tended to be dedrased with increasing cadmium level, but the contents of magnesium, calcium and ash tended to be increased.
