Relationship of cadmium levels among blood, urine, and diet in a general population
It has been established that the diet is the major source of exposure to cadmium (Cd) among the general population, and that cigarette smoking will be an additional source of non-occupational exposure to this metal. From the viewpoint of evaluation, it was stated that Cd in blood should be considered primarily as an indicator of recent exposure, while urinary Cd mainly reflects Cd body burden when Cd exposure is low and kidney impairment is absent, but may be influenced by current Cd exposure when Cd exposure is intense. Although a few experimental studies have been reported on the quantitative relation among the indicators of Cd exposure, report which establish and evaluate the correlations among these parameters in a general population are scarce. The present study was initiated to examine the relation of the Cd level in blood (Cd-B) with the Cd intake through diet (Cd-D) and the excretion of Cd into urine (Cd-U) among those with no known exposure to Cd. The Cd-U was examined both in terms of the level in the spot urine (Cd-Us) and as the amount in the 24-hr urine sample (Cd-U24).
