Growing evidence suggests that maternal exposures to endocrine disrupting chemicals during pregnancy may lead to poor pregnancy outcomes and increased fetal susceptibility to adult diseases. Polybrominated diphenyl ethers (PBDEs), which are ubiquitously used flame-retardants, could leach into the environment; and become persistent organic pollutants via bioaccumulation. In the United States, bl...

Electronic waste recycling operations in some parts of Asia are conducted using rudimentary techniques which result in workplace and environmental contamination with toxic metals and persistent organic pollutants. This study reports concentrations of 14 polybrominated diphenyl ethers (PBDEs), from tri- to deca-brominated, in 31 samples of soil, sediment, dust or ash collected in the vicinity of...

Anew idea in receptormodeling is proposed, which utilizes a geometric eigenspace projection combinedwith amild alternative matrix updating technique. The eigenspace projection determines the sources or characteristic patterns as vertices that can span all measurements in a multidimensional eigenspace. The mild alternative matrix updating algorithm refines the results determined by the eigenspac...

In the present work, we analyzed whether polybrominated diphenyl ethers (PBDEs) (47, 99, 100 and 209) interfere with the effect of 17β-estradiol on the proliferation and apoptosis of the MCF-7 cell line. MCF-7 cells were cultured in DMEM without phenol red; upplemented with 5% charcoal-treated fetal bovine serum for 3 days with 10 nM 17β-estradiol; with 0.1 μM, 0.5 μM or 1 μM of the tested PBDE...

Polybrominated diphenylethers (PBDEs) are synthesized chemicals essential to minimize accidents and deaths resulting from fire-outbreaks. Despite their usefulness, public health concern is on the increase over their use. PBDE is global in use, persistent in the environment, and possess the ability to bio-accumulate. Previous studies have suggested that they may interfere with thyroid hormone ho...

The spatial distribution of polybrominated diphenyl ethers (PBDEs) and several alternative non-PBDE, non-regulated brominated flame retardants (BFRs) in air and seawater and the air-seawater exchange was investigated in East Greenland Sea using high-volume air and water samples. Total PBDE concentrations (Ó₁₀PBDEs) ranged from 0.09 to 1.8 pg m⁻³ in the atmosphere and from 0.03 to 0.64 pg L⁻¹ in...

Screening of estrogenic activity on dichloro diphenyl trichloroethane (DDT), dichloro diphenyl dichloro ethylene (DDE), dieldrin, heptachlor, aldrin, chlordane, lindane, polybrominated diphenyl ethers (PBDE) and parabens was compared using Organization for Economic Cooperation and Development (OECD) test guideline 455 (TG455). The estrogenic activity of DDT was 58,000-fold (PC50, 1.67 × 10(-6) ...
