Abstract

The aim of the present study was to clarify the relationship between urinary cadmium concentration (U-Cd) and total cadmium intake (T-Cd) based on individual data of Cd in urine. Morning urine specimens were collected from 198 persons (100 men with average age of 45.8 years and 98 women with average age of 50.7 years) living in the Kakehashi River basin in Ishikawa Prefecture, Japan. The method used to calculate T-Cd basically mirrored that used in our previous study. Correlation coefficients between U-Cd and T-Cd of 0.879 and 0.835 were obtained in men and women, respectively, with both values statistically significant. Therefore, T-Cd is confirmed to be a useful indicator for external Cd exposure even on the basis of individual data of U-Cd.
