title: Polybrominated diphenyl ethers (PBDEs) and indicator polychlorinated biphenyls (PCBs) in foods from China: levels, dietary intake, and risk assessment.
abstract: A national survey of polybrominated diphenyl ethers (PBDEs) and indicator polychlorinated biphenyls (PCBs) congeners in various foodstuffs from the Chinese total diet study (TDS) performed in 2007 was conducted for the first time. Meats and aquatic foods had the highest average sum PBDEs (192.5 and 190.6 pg g⁻¹ fresh weight, respectively). For indicator PCBs, the highest average concentration was found in aquatic foods (628.7 pg g⁻¹ fresh weight). On the basis of measured PBDE and indicator PCB levels, the dietary intake estimate was subsequently calculated for the nonoccupationally exposed population in China. For adults, average estimated dietary intakes of PBDEs and indicator PCBs were 0.76 and 2.34 ng kg⁻¹ bw day⁻¹, respectively. Health risk assessment of PBDEs using a MOE approach recommended by EFSA suggested unlikely health concern with respect to current dietary intake of PBDEs in China.
