Abstract |
The purposes of this study were to improve the standard analytical method for decabromodiphenyl ether (deca-DBE) and investigate the concentrations of brominated flame retardants such as the hexabromocyclododecanes (HBCDs) and deca-DBE in water (n=8) and ambient air (n=6). The HBCDs were pretreated via hydrophilic-lipophilic balanced solid-phase extraction and analyzed by LC/MS/MS, affording limit of quantification (LOQ) values of 0.22~0.44 ng/L and 0.24~0.85 pg/m3 in water and air, respectively. In air, the concentration of HBCDs, among which the γ-isomer was the most prominent, ranged from
