title: Assessment of dietary intake of polychlorinated dibenzo-p-dioxins and dibenzofurans and dioxin-like polychlorinated biphenyls from the Chinese Total Diet Study in 2011.
abstract: The concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) as well as dioxin-like polychlorinated biphenyls (dl-PCBs) were measured in food samples from the fifth Chinese Total Diet Study (TDS) performed in 2011. A total of 152 composite samples from various food groups were analyzed by high resolution gas chromatography-high resolution mass spectrometer (HRGC-HRMS). The dietary intakes of PCDD/Fs and dl-PCBs were subsequently estimated for the adult from various regions in China. The mean dietary intake of PCDD/Fs and dl-PCBs was 20.1 pg TEQ kg(-1) bw month(-1) (WHO-TEF of 1998) within a range of 4.2 pg TEQ kg(-1) bw month(-1) to 53.7 pg TEQ kg(-1) bw month(-1) which were all much lower than the provisional tolerable monthly intake (PTMI) established by Joint FAO/WHO Expert Committee on Food Additives (JECFA). By comparing with results from previous Chinese TDS, a decline of the average dietary intake was observed from 2000 to 2011, but a notable elevation was observed in some regions partly stem from increasing contamination levels in certain foods.
