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...
متن کاملPolybrominated diphenyl ethers (PBDEs) in house dust in Beijing, China.
Eleven house dust samples were collected in Beijing to quantify 42 different polybrominated diphenyl ethers (PBDEs). Total PBDEs concentrations ranged from 140 to 1,300 ng g(-1). The dominant PBDEs congener identified was BDE 209, which made up more than 70% of all PBDEs congeners. Concentrations of PBDEs in Chinese house dust were lower than in other countries. The most polluted areas were ele...
متن کاملRelease of polybrominated diphenyl ethers from wastewater in China
Introduction Polybrominated diphenyl ethers (PBDEs) are a class of flame retardants that were added to thousands of consumer products, such as thermoplastics, electronic equipment, and textiles (Hale et al., 2001).Research has revealed that municipal sewage could be a significant source of PBDEs contamination that is ubiquitous throughout the environment (North, 2004; Song et al., 2006). The Pe...
متن کاملPolybrominated diphenyl ethers in atmosphere and soil of a production area in China: levels and partitioning.
Polybrominated diphenyl ethers (PBDEs) were measured in atmosphere and soil samples taken in winter and summer at a PBDE production area of Laizhou Bay in China. The concentrations of Sigma11PBDE were 0.017-1.17 ng/m3 in gaseous phase, 0.5-161.1 ng/m3 in particulate phase, and 73-2629 ng/g dry weight in soil samples. The PBDE congener pattern in the gaseous phase differed from that in the parti...
متن کاملComposition, distribution, and characterization of polybrominated diphenyl ethers in sandstorm depositions in Beijing, China.
This study was conducted to determine the concentration of 8 polybrominated diphenyl ethers (PBDEs) in sandstorm depositions in Beijing, China. The PBDE concentrations in 10 samples collected in Beijing ranged from 8.47 to 29.02 ng g(-1), with BDE-209 as the predominant congener (>85%). Principal component analysis revealed that the major source of PBDEs in Beijing may be potentially associated...
