Interrelationships among zinc, copper, lead, and cadmium in food, feces, and organs of humans.

Concentrations of zinc, copper, lead, and cadmium were determined in 20 samples of food collected over a period of 20 days, 221 samples of feces collected over a period of 5 days from 19 males, 17 females, and 11 children and 85 samples each of renal cortex and liver from autopsied human cadavers in...

description Concentrations of zinc, copper, lead, and cadmium were determined in 20 samples of food collected over a period of 20 days, 221 samples of feces collected over a period of 5 days from 19 males, 17 females, and 11 children and 85 samples each of renal cortex and liver from autopsied human cadavers in order to investigate the relationships among the four metals and among the various martices. In food the highest correlation was observed between copper and zinc (0.34). In feces the highest correlation was also between copper and zinc (0.45). In the highest correlation between cadmium and zinc (0.33), but that in the renal cortex was between copper and cadmium (0.52). These findings suggest that the relationships among the concentrations of the four metals in food and feces are almost equal to each other, but differ greatly from the concentrations in human organs due to the differing metabolic actions of the metals once they are absorbed into the body. In addition, it was observed that zinc and cadmium concentrations in the renal cortex increase with age, but copper and lead concentrations do not show much variation with age.
