Objectives: To estimate the normal range of blood and urine cadmium levels using data from occupationally non-exposed office workers to cadmium in selected Korean women.
Methods: A total of 437 women from healthy office workers were analyzed. To analyze blood and urine cadmium levels, blood and urine samples of study subjects were collected carefully and analyzed. Using a structured questionnaire, characteristics of the study subjects were investigated by well trained interviewers.
Results: Mean blood cadmium concentration (CdB) was 0.46 ㎍/ℓ (GM; 0.16), whereas mean urine cadmium concentration (CdU) was 0.94 ㎍/g creatinine (GM; 0.37). A significant increase of cadmium levels in blood and urine was observed by the rise of age (p=0.007; p=0.002, respectively). In the analysis of smoking state, blood and urine cadmium levels were higher in current smokers than in nonsmokers. In the multiple regression analysis, the rise of age and urrently smoking were observed as a significant factor associated with cadmium level.
Conclusion: These findings suggest that mean cadmium level in blood and urine indicated a relatively low level,
although the rise of age and currently smoking were observed as a significant factor related to cadmium level. It can be used for the basic data to prevent harmful effects of cadmium exposure among female workers occupationally exposed to cadmium.
