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.

Background: The association between brominated flame retardants (BFRs) and periodontitis has remained unclear.
Methods: This research included adult participants from NHANES cycles 2009-2014. Survey-weighted generalized linear regressions were used to explore the associations between BFR exposure and periodontitis.

The pollution potential of a municipal wastewater treatment plant (WWTP) in Bursa, Türkiye, in terms of organochlorine pesticides (ΣOCPs), polychlorinated biphenyls (ΣPCBs), and polybrominated diphenyl ethers (ΣPBDEs), was investigated in air samples. Concentrations were determined using polyurethane foam disk samplers at key processes, such as the aeration tank (AT) and settling chamber (SC) of the WWTP and the background area (BA) at an urban site. Atmospheric concentration levels of PBDEs at the SC are 1.

This study investigated the bioaccumulation of halogenated organic pollutants (HOPs) in three types of feathers from laying hens through exposure experiments. The HOPs included lipophilic polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), as well as proteinophilic perfluoroalkyl carboxylic acids (PFCAs). Concentrations of PCBs, PBDEs, and short-chain PFCAs (≤8) were significantly higher in the body feathers than in the primary feathers, while long-chain PFCAs (>8) showed no significant differences among primary, tail, and body feathers.
