Contamination of U.S. Butter with Polybrominated Diphenyl Ethers from Wrapping Paper

OBJECTIVES Our aim was to report the first known incidence of U.S. butter contamination with extremely high levels of polybrominated diphenyl ethers (PBDEs). METHODS Ten butter samples were individually analyzed for PBDEs. One of the samples and its paper wrapper contained very high levels of higher-brominated PBDEs. Dietary estimates were calculated using the 2007 U.S. Department of Agricult...

Simultaneous Determinations of Methoxylated Polybrominated Diphenyl Ethers and Polybrominated Diphenyl Ethers in Dairy Products from China by GC-MS

In this paper, the method of simultaneous determinations of methoxylated polybrominated diphenyl ethers and polybrominated diphenyl ethers in dairy products from China was investigated. PBDEs are widely used brominated flame retardant, which are increasingly reported in the environment. MeO-PBDEs are structural analogs to PBDEs, and reported as natural products and novel pollutants present in t...

Assessment of polychlorinated biphenyls and polybrominated diphenyl ethers in Tibetan butter.

The Tibetan plateau is considered a potential cold trap for persistent organic pollutants (POPs) and plays an important role in the global long-range transport of these compounds. This present work surveyed the concentrations of polychlorinated biphenyl (PCBs) and polybrominated diphenyl ethers (PBDEs) in Tibetan butter samples collected from different prefectures in Tibet autonomous region (TA...

Environmental Threats of Natural Water Contamination with Polybrominated Diphenyl Ethers (PBDEs)

Polybrominated diphenyl ethers (PBDEs) are a class of synthetic halogenated organic compounds used in numerous polymer-based commercial and household products such as textiles, furniture, and electronics, to increase their flame ignition resistance and to meet increasingly strict fire safety standards. Release of PBDEs to the environment can occur during manufacturing and processing operations,...
