Polybrominated diphenyl ethers in California wastestreams

Chemosphere, 2009
Polybrominated diphenyl ethers (PBDEs) are used in consumer products, including electronics, fabrics, and polyurethane foam. Exposures may occur during the products' useful lifetime and also after the products' disposal. A survey of California wastestreams (e-wastes, autoshredder waste and wastewater sewage sludge) attempted to assess the relative ...

Model for photodegradation of polybrominated diphenyl ethers

Environmental Science and Pollution Research, 2014
Polybrominated diphenyl ethers (PBDE) were, and in some countries still are, used as flame retardants for plastic materials. When released from plastics, PDBE cause harm to the environment. This creates the incentive for further investigation of the PBDE degradation.

Sorption of polybrominated diphenyl ethers by microplastics

Marine Pollution Bulletin, 2019
The sorption of polybrominated diphenyl ethers (PBDEs) onto polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyamide (PA) microplastics was analyzed using different kinetic and isotherm models, and under various environmental conditions, including temperature, pH, salinity and dissolved organic matter (DOM).

Synthesis of Hydroxylated and Methoxylated Polybrominated Diphenyl Ethers − Natural Products and Potential Polybrominated Diphenyl Ether Metabolites

European Journal of Organic Chemistry, 2003
AbstractHydroxylated and methoxylated polybrominated diphenyl ethers (OH‐PBDEs and MeO‐PBDEs) may be natural products or they may be formed as metabolites of polybrominated diphenyl ethers (PBDEs), frequently used as flame retardants. The aim of this work was to synthesize authentic OH‐ and MeO‐PBDE reference standards for analytical and toxicological ...

Identification of Hydroxylated Polybrominated Diphenyl Ether Metabolites in Blood Plasma from Polybrominated Diphenyl Ether Exposed Rats

Environmental Science & Technology, 2005
Polybrominated diphenyl ethers (PBDEs) are ubiquitous environmental contaminants due to their use as flame retardants. Similarly to PCBs, the PBDEs are metabolized to hydroxylated metabolites (OH-PBDEs) in mammals. In the present study equimolar doses of seven environmentally relevant PBDE congeners were given intraperitoneally as a mixture to rats ...

Identification and Quantification of Polybrominated Diphenyl Ethers and Methoxy-Polybrominated Diphenyl Ethers in Baltic Biota

Environmental Science & Technology, 1997
Polybrominated diphenyl ethers (PBDPEs) and, for the first time, methoxy-polybrominated diphenyl ethers (MeO-PBDPEs) have been positively identified and quantified in various biotic samples including herring, salmon, seal, man (only PBDPEs), and commercial fish oils. The presence of these compounds was confirmed in the above samples by mass spectra and

Polybrominated Diphenyl Ethers Contamination of United States Food

Environmental Science & Technology, 2004
Elevated levels of polybrominated diphenyl ethers (PBDEs), a type of brominated flame retardant, were recently detected in U.S. nursing mothers' milk. These halogenated compounds chemically and toxicologically resemble others such as polychlorinated biphenyls (PCBs), whose route of intake is almost exclusively through food of animal origin.

Photochemical degradation of polybrominated diphenyl ethers in microreactor

Research on Chemical Intermediates, 2015
Knowledge of reaction mechanism and kinetics of persistent organic pollutants are crucial to development a removal technology. Feasibility of photochemical microreactor utilization as a tool for experimental investigation of photochemical degradation of polybrominated diphenyl ethers (PBDE) was studied.

Sodium borohydride reduction of individual polybrominated diphenyl ethers

Chemosphere, 2012
Many chemicals in use today lack appropriate documentation on their environmental properties, fate, and effects. To counteract this lack of documentation it is vital to thoroughly investigate a compound's fate in the environment before it comes into use.

Polybrominated diphenyl ether in sewage sludge in Germany

Chemosphere, 2007
Sewage sludge samples from 11 municipal waste water treatment plants in Germany were collected from March 2002 to June 2003. Total Tri- to HpBDE concentrations (sum of significant congeners BDE 28, 47, 99, 153, 154 and 183) ranged from 12.5 to 288 (median 108) and DeBDE (BDE 209) concentrations from 97.1 to 2217 (median 256) ng/gd.m.
