Patterns and dietary intake of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans in food products in China
The health risk of polychlorinated dibenzo-p-dioxins and dibenzofurans（PCDD/Fs） and dioxin-like PCBs（d1-PCBs） to human being should be assessed regularly.To evaluate the contamination levels in various food products in the Chinese market and to assess the dietary exposure of the Chinese population,11 varieties of food groups totaling 534 samples including beef and mutton,chicken and duck,pork,fish and seafood,milk and dairy products were evaluated.The average concentrations of PCDD/Fs in all groups ranged from0.291 to 8.458 pg/g whole weight（w.w.）.The average toxic equivalency concentrations were from 0.012 pg TEQ/g w.w.for cereal to 0.357 pg TEQ/g fat for marine oil.OCDD and2,3,7,8-TCDF were the dominant congeners in foodstuffs.The dietary estimated mean intake for the Chinese rural and urban populations were 0.555 and 0.514 pg TEQ/kg body weight/day,respectively,however,the cereal group exposure were higher to the estimate daily intake and contributed 81%for rural and 48%for urban population,followed by fish and seafood which contributed 4%and 15%to the estimate daily intake.The estimated dietary intakes were compared with the toxicological reference values and showed that both rural and urban populations were well below those values.
