Urinary cadmium (UCd) is a good indicator of long-term exposure to cadmium. UCd concentrations resulting from juvenile cadmium exposure in 3 sub-districts of Tak Province, Thailand, were investigated. The target population was divided by gender and into 2 age subgroups: 9–12 and 13–15 years. A total of 748 urine samples were collected and analyzed by spectrophotometer. All samples had UCd of more than 1.0 μg/g creatinine (Cr). Total UCd means among the 3 sub-districts were 1.31, 1.01, and 0.87 μg/g Cr; the Thai population mean is 0.5 μg/g. The difference among the three sub-districts was statistically significant (p < 0.05). Total means for UCd were 1.13 μg/g Cr for boys, 1.00 for girls, 1.01 μg/g Cr for those 9–12 years old, and 1.18 for those 13–15. UCd concentrations were not significantly different between genders and age groups. Likely dietary sources of cadmium exposure for the subject population were surveyed. 相似文献
