objective: to determine the levels of polychlorinated biphenyls (pcbs) and polybrominateddiphenyl ethers (pbdes) as persistent organic pollutants (pops) in serum of primiparous women at the third trimester of pregnancy and identify the main determinants of pops levels such as socio-demographic, lifestyle, and diet in tehran. materials and methods: one- hundred eighty five serum samples from two...

Polybrominated diphenyl ethers (PBDEs) along with hydroxylated polybrominated diphenyl ethers (OH-PBDEs) and methoxylated polybrominated diphenyl ethers (MeO-PBDEs) were found in plant and soil samples collected surrounding a seafood processing factory and a seafood market in China. The profiles of MeO-PBDE congeners were different between seafood processing factory and seafood market. The dete...

polybrominated diphenyl ethers (pbde) are widely employed as flame retardants and constitutea group of emerging pollutants of high persistence. the degradation of different pbde commercial mixtures(penta-, octa- and deca-bde) by the white-rot fungus trametes versicolor under aerobic conditions wasstudied. this work demonstrates the capacity of t. versicolor to degrade three different pbde comme...

Polyhalogenated dibenzo-p-dioxins are arguably among the most toxic molecules known to man. In addition to anthropogenic sources, marine invertebrates also harbor polybrominated dibenzo-p-dioxins of as yet unknown biogenic origin. Here, we report that the bmp gene locus in marine bacteria, a recently characterized source of polybrominated diphenyl ethers, can also synthesize dibenzo-p-dioxins b...

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...
