| Abstract:: |
| Objective To determine lanthanide concentrations in dietary foods and main organs or tissues for Chinese adult man and to estimate their daily intakes by ingestion and organ or tissue burdens. Methods Ten kinds of organ or tissue samples collected in autopsy from 21 supplemental subjects of 4 areas with different dietary types in China who died suddenly,and had been healthy and normal before death.The concentrations of 11 lanthanide in foods and 14 lanthanide in these organ or tissue samples,including those collected from 31 subjects in the past,were analyzed by using ICP-MS or INAA technique as well as necessary QC measures.With uses of the local diet composition and relevant organ or tissue weights for Chinese Reference Man,their daily intakes and organ or tissue burdens were estimated. Results The concentrations of 14 lanthanide in 12 categories of foods and 10 kinds of organ or tissue samples,their dietary daily intakes and organ or tissue burdens for Chinese adult men were obtained. Conclusion Besides updating the relevant data of La,Ce and Eu in 5kinds of organ or tissue and diet,this research obtained data on concentrations of other 11 lanthanide in Chinese foods and 10 kinds of organ or tissue,their daily intakes and burdens for the first time in China.The results provide more systematic bases for developing the parameters of Chinese Reference Man than before.This study provides also comparative data for different kinds of lanthanide,foods,organs or tissues and also the background values of Chinese soil. |
