Dietary intake of polychlorinated dioxins, furans and dioxin-like polychlorinated biphenyls from foods of animal origin in China

Abstract

Four food groups of animal origin from the Chinese Total Diet Study (TDS) in 2000 were analysed for 17 polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and 12 dioxin-like polychlorinated biphenyls (PCBs). The samples were from four regions, covering 12 provinces of China. PCDD/Fs, expressed as WHO toxic equivalents (TEQ), ranged from 0.02 to 0.28 pg TEQ g-1 and dioxin-like PCBs ranged from 0.01 to 0.24 pg TEQ g-1 (wet weight, ND = LOD), in all samples. Using food consumption data from a 3-day household dietary survey, daily dietary intake of dioxin-like compounds from foods of animal origin in China was estimated. Daily intake among regions ranged 0.09-0.59 pg TEQ kg-1 body eight day-1.

Cooking Process: A New Source of Unintentionally Produced Dioxins?

“…The average PCDD/F concentration of raw beef in this study was 0.069 pg of TEQ g À1 (fresh weight), which is similar to the level for meat reported in a national survey of foods of animal origin in China (0.06À0.21 pg of TEQ g À1 ). 19 This means the beef used in this study is representative of that consumed in China.…”

Assessment of dietary intake of polychlorinated dibenzo-p-dioxins and dibenzofurans and dioxin-like polychlorinated biphenyls from the Chinese Total Diet Study in 2011

“…In our previous studies, dietary intake of PCDD/Fs and dl-PCBs of the Chinese population was estimated from Chinese TDS in 2000 and again in 2007 showing a slightly increasing temporal trend (Li et al, 2007;Zhang et al, 2013a). The aim of the present study is to present the contamination levels of PCDD/Fs and dl-PCBs in main Chinese foodstuffs from the latest Chinese TDS in 2011 and assess the dietary intake as well as health risk.…”

Polychlorinated dibenzo-p-dioxin and dibenzofurans (PCDD/Fs), polybrominated diphenyl ethers (PBDEs), and polychlorinated biphenyls (PCBs) monitored by tree bark in an E-waste recycling area

“…Recoveries of all 13 C 12 -labeled surrogates were between 35% and 110% for all samples, which is in the acceptable range established by the USEPA 1613B, 1614, and 1668A. The Laboratory has successfully participated in an inter-laboratory comparison study of PCDD/Fs, PBDEs, and PCBs in different matrices organized by the Norway Institute of Public Health (Norwegian Institute of Public Health, 2005) (Li et al, 2007;Wen et al, 2008).…”
