摘 要:目的 研究太原市普通人群血清中多溴联苯醚(PBDEs)负荷水平.方法 2010年在太原市共采集了42份普通人群血清样品,用固相萃取-气相色谱-负化学源-质谱法测定了样品中溴代联苯醚(BDE)-17、BDE-28、BDE-47、BDE-66、BDE-99、BDE-100、BDE-153、BDE-154、BDE-183 和BDE-209,计算PBDEs合计值(∑PBDEs).结果 在测定的血清样品中,∑PBDEs范围为2.09-66.74 ng/g脂重(lipid weight,1w),中位数和均值分别为6.32 ng/g 1w和9.84 ng/g 1w.BDE-209为ΣPBDEs主要贡献来源,其含量在未检出至64.99.ng/g 1w范围内,中位数为4.11 ng/g 1w,其贡献率为67.6%;其次为BDE-153,其含量在0.29-4.92 ng/g 1w范围内,中位数为0.62 ng/g 1w,其贡献率为10.1%.结论 2010年太原市普通人群血液中PBDEs负荷水平较低.Objective This study was conducted to characterize polybrominated diphenyl ethers (PBDEs)load in human serum of Taiyuan city in 2010.Methods A total of 42 blood samples were collected in Taiyuan city,2010.Solid-phase extraction(SPE)-gas chromatography-negative chemical ionization-mass spectrometry method was used to measure the concentration of brominated diphenyl ethers (BDE)-17,BDE-28,BDE-47,BDE-66,BDE-99,BDE-100,BDE.153,BDE-154,BDE-183 and BDE-209 and ∑PBDEs was calculated.Results Of the tested serum samples,∑PBDEs ranged from 2.09 to 66.74 ng/gof lipid weight(1w),the median and mean was 6.32 ng/g 1w and 9.84 ng/g 1w.respectively.BDE-209 was the main source of ∑PBDEs and its concentration ranged from no dectecion to 64.99 ng/g 1w.the median was 4.11 ng/g 1w,accounting for 67.6%of ∑PBDEs.Second source was BDE-153 and its concentration ranged from 0.29 to 4.92 ng/g 1w,the median was 0.62 ng/g 1w accounting for 10.1% of ∑PBDEs.Conclusion The overall load of PBDEs in the serum of local residents was low in 2010.
