title: Assessment of the Cadmium Exposure in the Blood, Diet, and Water of the Pumi People in Yunnan, China.
abstract: Cadmium (Cd) is considered as one of the most toxic and carcinogenic heavy metals. Accumulation of Cd in the human body can cause multiorgan dysfunction. Long-term irrational mining activities have led to serious Cd pollution in soil, water, and even agricultural products. Therefore, evaluating the Cd exposure levels of people living in mining areas is of great importance. In the current study, we chose the Pumi people who lived in Jinding and Tongdian towns of Lanping county in Yunnan province, China, to do the on-site nutritional epidemiology investigation and laboratory detection. We analyzed the content of the Cd in peripheral blood and mixed dietary, as well as water samples in the Pumi residents of the two towns. Results showed that the blood Cd levels of people in Jinding town, which is nearer the mining district, were statistically significantly higher than those in Tongdian town. The P 50 of blood Cd level of the two towns was 0.64 ng/mL. In addition, the P 50 of the mixed diet of the two towns was 8.32 μg/kg. There was a weak correlation between blood Cd levels and Cd exposure in the mixed diet, PTDI, and PTWI of the Pumi people. In addition, higher concentrations of Cd were observed in the water of Jinding town, indicating people in Jinding town risking more Cd exposure. These results indicated that diet and water are critical factors of Cd exposure for the residents and the nearer people living to mining district risking the more Cd exposure.
