Occurrence and profiles of halogenated phenols, polybrominated diphenyl ethers and hydroxylated polybrominated diphenyl ethers in the effluents of waste water treatment plants around Huang-Bo Sea, North China

Science of The Total Environment, 2018
Halogenated organic pollutants (HOPs), as ubiquitous environment contaminants, have attracted increasing concerns due to the potential adverse health impacts on organisms and even humans. Waste water treatment plants (WWTPs) are one source of HOPs to the environment through their discharge of treated effluent.

[Study on structure, charge and spectrum for para-halogenated diphenyl ethers through density functional theory].

Guang pu xue yu guang pu fen xi = Guang pu, 2015
The present paper mainly researched the molecular geometry, charge distribution and spectrum vibration of diphenyl ether and its 3 kinds of para-halogenated diphenyl ethers based on density functional theory (DFT). The infrared and Raman spectrum vibration frequency for para-halogenated diphenyl ethers was calculated based on respective optimal ...

Low-Level Alternative Halogenated Flame Retardants (Ahfrs) in Indoor Dust from Adelaide, South Australia Decades Since National Legislative Control on Polybrominated Diphenyl Ethers (Pbdes)

SSRN Electronic Journal, 2021
Since commercial polybrominated diphenyl ethers (PBDEs) have been globally banned or restricted in 2000s, alternative halogenated flame retardants (AHFRs) appear increasingly dominant over PBDEs in many countries/regions. In this study, low levels of AHFRs were unexpectedly observed in the indoor dust from Adelaide, South Australia.

Prediction of vapour pressures for halogenated diphenyl ether congeners from molecular descriptors

Environmental Science and Pollution Research, 2002
Polychlorinated diphenyl ethers (PCDE) and polybrominated diphenyl ethers (PBDE) have both been identified as environmental contaminants. The physical properties are important in determining the distribution and fate of organic contaminants in the environment.

Determination of emerging halogenated flame retardants and polybrominated diphenyl ethers in serum by gas chromatography mass spectrometry

Journal of Chromatography A, 2013
Emerging flame retardants are used in a great variety of household goods and thus have the potential to pollute our indoor environment. Health concerns regarding exposure to these flame retardants demand new methods to survey their occurrence in humans.

Analysis of polybrominated diphenyl ethers and emerging halogenated and organophosphate flame retardants in human hair and nails

Journal of Chromatography A, 2015
A method for the digestion, extraction, fractionation, and analysis of three classes of flame retardants, including 36 polybrominated diphenyl ethers (PBDEs), 9 halogenated alternative flame retardants (AFRs), and 12 organophosphate esters (OPEs) in human hair and nail samples was developed.

Polybrominated diphenyl ethers and alternative halogenated flame retardants in mangrove plants from Futian National Nature Reserve of Shenzhen City, South China

Environmental Pollution, 2020
Halogenated flame retardants (HFRs) are ubiquitous in the environment, but little information is available about the bioaccumulation of HFRs in mangrove plants. In this study, three mangrove plant species were collected from Futian National Nature Reserve of Shenzhen City, South China to investigate the bioaccumulation of polybrominated diphenyl ethers

Photochemical Formation of Halogenated Dioxins from Hydroxylated Polybrominated Diphenyl Ethers (OH-PBDEs) and Chlorinated Derivatives (OH-PBCDEs)

Environmental Science & Technology, 2009
The potential photochemical formation of polybrominated and mixed halogenated dibenzo-p-dioxins (PBDDs and PXDDs) from hydroxylated polybrominated and polybrominated/ chlorinated diphenyl ethers (OH-PBDEs and OH-PBCDEs) in aqueous solution was studied. The ortho-hydroxylated BDE47 derivative 6-OH-BDE47, and chlorinated derivatives 3-Cl-6-OH-BDE47, 5-Cl-

Bioaccumulation of polybrominated diphenyl ethers and several alternative halogenated flame retardants in a small herbivorous food chain

Environmental Pollution, 2013
Little is known about the bioaccumulation behavior of polybrominated diphenyl ethers (PBDEs) and other halogenated flame retardants (HFRs) in plants and in herbivores. In the present study, PBDEs and several alternative HFRs (AHFRs) were examined in a small herbivorous food chain (paddy soils-rice plant-apple snails) from an electronic waste recycling ...

Contamination and distribution of heavy metals, polybrominated diphenyl ethers and alternative halogenated flame retardants in a pristine mangrove

Marine Pollution Bulletin, 2016
Owing to the expanding metal and electronics industries, pollution in the Pearl River Estuary needs special concern. Given the hydrodynamic effect, the pristine mangrove in Qi'ao Island would be contaminated by tidal flushing. Thus, we examined (1) the contamination of pollutants in this mangrove, including heavy metals, polybrominated diphenyl ethers (
