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.

Association between brominated flame retardants and periodontitis: a large-scale population-based study.

Front Public Health

January 2025

The Affiliated Taizhou People's Hospital of Nanjing Medical University, Taizhou School of Clinical Medicine, Nanjing Medical University, Taizhou, 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.

Article Synopsis
  • PBDEs are synthetic compounds used as flame retardants, raising health concerns due to their toxicity and accumulation in the environment, with food and dust as main exposure sources.
  • The study analyzed dust from 31 cars and 14 airplanes for specific PBDE types, estimating exposure for infants, toddlers, and adults, using gas chromatography for detection.
  • Results showed BDE-209 was most prevalent, but overall exposure levels were low, with all hazard quotients below 1, indicating no significant health risk from dust ingestion for the populations studied.

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.

Accumulation of lipophilic and proteinophilic halogenated organic pollutants (HOPs) in the different types of feathers of laying hens.

J Hazard Mater

December 2024

State Key Laboratory of Organic Geochemistry and Guangdong Provincial Key Laboratory of Environmental Protection and Resources Utilization, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou 510640, China; Guangdong-Hong Kong-Macao Joint Laboratory for Environmental Pollution and Control, Guangzhou 510640, China; CAS Center for Excellence in Deep Earth Science, Guangzhou 510640, China.

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.

Persistent organic pollutants and fatty acids in humpback whales: Antarctic and Chilean feeding and Brazilian breeding sites.

Sci Total Environ

December 2024

Instituto Oceanográfico, Universidade de São Paulo, Praça do Oceanográfico, 191, São Paulo, SP 05508-120, Brazil.

Article Synopsis
  • The study examined the fatty acid profiles and persistent organic pollutant (POP) levels in humpback whales from different regions of the Southern Ocean, Chile, and Brazil.
  • Significant differences were found in the fatty acid compositions, with whales in the Strait of Magellan showing a diet high in higher trophic level prey, while those from the Antarctic Peninsula and Brazil reflected a krill-based diet.
  • Elevated concentrations of pollutants, especially PCBs, were observed in whales from the Strait of Magellan, indicating a connection between their dietary habits and exposure to contaminants.
