Polybrominated diphenyl ethers (PBDEs) are a class of synthetic halogenated organic compounds used in commercial and household products, such as textiles, furniture, and electronics, to increase their flame ignition resistance and to meet fire safety standards. The demonstrated persistence, bioaccumulation, and toxic potential of these compounds in animals and in humans are of increasing concer...

In this study, polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes (HBCDs) and polychlorinated biphenyls (PCBs) were determined in human scalp hair from Vietnam. Levels of PBDEs and HBCDs were significantly higher in hair of e-waste recycling workers in Bui Dau (e-waste recycling site), an e-waste recycling site than those in general residents in Bui Dau, Dong Mai (lead battery recy...

Understanding Branches Out Insights into PBDE Impacts on Brain Development Polybrominated diphenyl ether (PBDE) flame retardants and their hydroxylated metabolites are structurally similar to thyroid hormone. A detailed study now provides one of the most insightful assessments to date of how environmentally relevant levels of PBDEs may impair brain development by interfering with thyroid hormon...

During recent years, a marked increase in the levels of brominated flame retardants (BFRs), especially polybrominated diphenyl ethers (PBDEs), in human tissues all over the world have been observed (Scheter et al., 2000; Tomsen et al., 2002). It is mainly due to the following facts: their production and use have undergone a dramatic increase starting in the 1980s (Sjödin et al., 2004) and their...

BACKGROUND Until their phase-out between 2005 and 2013, polybrominated diphenyl ethers (PBDEs) were added to household products including furniture, rugs, and electronics to meet flammability standards. Replacement brominated flame retardant (BFR) chemicals, including 2-ethylhexyl-2,3,4,5 tetrabromobenzoate (TBB) and bis(2-ethylhexyl) 2,3,4,5-tetrabromophthalate (TBPH), which are components of ...

polybrominated diphenyl ethers (pbdes) have been widely used in many products as flameretardants, which resulted in their release into the environment. little is known about the impact of coexisting pbdes on organisms. in this study, the in vivo effects of bde-47 and bde-99 on a suite of biomarkers, acetyl cholinesterase (ache), ethoxyresorufin-o-deethylase (erod), glutathione-s-transferase (gs...

Continuous atmospheric sampling was conducted between 2010–2015 at Casey station in Wilkes Land, Antarctica, and throughout 2013 Troll Station Dronning Maud Antarctica. Sample extracts were analyzed for polybrominated diphenyl ethers (PBDEs), the naturally converted brominated compound, 2,4,6-Tribromoanisole, to explore regional profiles. This represents first report of seasonal resolution PBDE...

diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are persistent , lipophilic chemicals with different sources, pathways, and patterns of human exposure. Mixtures of PBDEs are present as noncovalently bound flame-retardant additives to synthetic fabrics, foams, or plastics in a variety of consumer products. Two mixtures, the penta-and octa-BDEs, are no longer used. Deca-BDE, the majo...

BACKGROUND Polybrominated diphenyl ethers (PBDEs) are ubiquitous environmental contaminants that may influence growth and development. OBJECTIVE We investigated the association between exposure to PBDEs via breast milk and anthropometric measurements in early childhood. METHODS The Pregnancy Infection and Nutrition (PIN) Babies studies followed a cohort of North Carolina pregnant women and ...

The populations of American (Anguilla rostrata) and European eels (Anguilla anguilla) have been declining rapidly in the last decades. Organic contaminants are suspected to be one of the possible causes for the decline; however, so far there have been few investigations of the uptake of specific compounds by different life cycle stages (e.g. freshwater or marine stage) and how the contamination...
