| 英文摘要 | Human hair and blood samples from persons living in the town of Wanshan, a mercury mine area in Guizhou Province of China, were collected and the quantitative speciation and structural information of Hg and S in hair samples and of Hg in erythrocyte and serum samples were studied using X-ray absorption spectroscopy. Least-squares fitting of the X-ray absorption near-edge spectra found that inorganic mercury is the major mercury species in hair samples (91.74%), while inorganic and methyl mercury are both about 50% of total mercury in RBC and serum samples, which is in agreement with the data obtained by acidic extraction, fractionation of Hg2+ and (CHHg+)-Hg-3 and quantification by ICP-MS. Curve-fitting analysis revealed that the Hg-S bond length and coordination number in hair were 0.248 +/- 0.002 nm and 3.10, respectively, while the S-Hg bond length and coordination number in hair were 0.236 +/- 0.002 nm and 4.05. The Hg-S bond length and coordination number in RBC were 0.251 +/- 0.003 mn and 4.09, respectively, while they were 0.228 +/- 0.002 nm and 4.08 in serum, respectively. The techniques for speciation, structural and binding information described in this study will find the potential application in similar studies of other elements. (C) 2007 Elsevier Inc.
