Whole-Body and Hair Retention of Cadmium in Mice

Abstract
The relationship between concentrations of cadmium in hair and in the whole body is of interest when discussing which biological sampling materials could be reliable indicators of cadmium accumulation in the body. When whole-body and hair concentrations of cadmium were followed at regular intervals up to 112 days after an intravenous injection of cadmium chloride tagged wih cadmium 109 in mice, a correlation coefficient of .99 was found. Retention of cadmium in different tissues was illustrated by organ assay and whole-body autoradiography and was especially pronounced in kidneys and pancreas.
