摘要: The concentrations of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), dioxin-like biphenyls (dl-PCBs) and polybrominated diphenylethers (PBDEs) in 33 breast milk samples collected 2006-2007 from primipara mothers close to four industrial areas Slovak Republic were determined. total PCDDs/PCDFs dl-PCBs expressed as TEQ based on WHO TEFs 1998 varied 5.0 51.8 pg g(-1) fat (median: 13.1 fat; mean: 18.0 fat). measurements seven PBDE congeners (IUPAC No. 28, 47, 99, 100, 153, 154, 183) performed for the first time human Slovakia. levels ranged between 0.22 1.62 ng fat, with median mean value 0.43 0.57 respectively. No statistically significant differences observed studied concentrations. Furthermore, this study presents results concerning daily intake (DI) compounds most vulnerable breast-fed infant population PCDD/PCDF dl-PCB DI an during 2 months life was estimated a range 14.4 230 kg(-1)b.w., 58.9 kg(-1)b.w.. values substantially exceeded tolerable (TDI) 1-4 kg(-1)b.w. recommended by WHO. dietary PBDEs be 0.69 7.1 kg(-1)b.w.d(-1), 1.7 kg(-1)b.w.d(-1).
