Continuing to the former report concerning the metabolism of copper andiron on adult men, the similar study was also perfomed on children.
The subjects were 6 healthy boys from 5.3. to 9.8m. years old.
The metabolic study was held through 15 days.
Average copper intake per child per day was 3.2mg., and urinary and fecal excretions were 0.1mg. and 1.3mg. respectively. The retention was 1.8mg. Converting these values to per kg. of body weight, 0.15mg. of intake and 0.08mg. of retention were obtained.
Average daily iron intake was 11.7mg., urinary and fecal excretion were 0.5mg. and 9.0mg. respectively, therefore and the retention was 2.3mg. per day. in this experiment, These were equal to 0.52mg. of intake and 0.11mg. of retention per 1kg. of body weight.
