Release 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...

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...

Polybrominated 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...

Polybrominated diphenyl ethers and polybrominated biphenyls in Australian sewage sludge.

This paper presents a brief review of the international scientific literature of polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs) in sewage sludge and a survey of these compounds in sewage sludge from 16 Australian wastewater treatment plants (WWTPs). The SigmaPBDE mean concentration in the Australian study was 1137microgkg(-1) dry weight (d.w.) (s.d. 1116) and ranged ...
