Abstract
The present study aimed to provide time trend of polybrominated dipheny1 ethers (PBDE) in serum obtained from Korean general population. The concentration of 7 ∑PBDE congeners (BDE-28, 47, 99, 100, 153, 154, and 183) was determined with 103 human serum collected at 2006. The concentrations of ∑PBDEs (sum of seven congeners) ranged from 0.13 to 31.8 ng g-1 lipid with the median ∑PBDEs concentration of 6.70 ng g-1 lipid. The correlation of PBDE congeners with demographic literature, the peak and schematic time trend of ∑PBDEs concentration was estimated. The concentration of ∑PBDEs decreased with time and the peak of ∑PBDEs was before 2001. Futhermore, 6 pooled serum samples covered from 2006 to 2013 were analyzed to observe temporal trend. The highest concentration of ∑PBDEs was shown in 2006 (5.98 ng/g lipid) followed by a decrease in 2013 (2.98 ng/g lipid). Each congener showed different decreasing rates of the concentration.
