Bioaccumulation of Polybrominated Diphenyl Ethers by Tubifex Tubifex

Effects of nitrogen and phosphorus concentrations on the bioaccumulation of polybrominated diphenyl ethers by Prorocentrum donghaiense.

The growth, cellular total lipids, bioaccumulation amount, and bioaccumulation factors (BAFs) of 2,4,4'-tribromodiphenyl ether (BDE28), 2,2',4,4'-tetrabromodiphenyl ether (BDE47), and 2,2',4,4',5-pentabromodiphenyl ether (BDE99) in a semi-continuous culture of Prorocentrum donghaiense were studied in relation to nitrate (0, 128, and 512 micromol/L) and phosphate (0, 8, and 32 micromol/L) concen...

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...

Bioaccumulation of polybrominated diphenyl ethers in harbor seals from the northwest Atlantic.

Polybrominated diphenyl ethers (PBDEs) were analyzed in blubber of harbor seals (Phoca vitulina concolor) collected between 1991 and 2005 along the northwest Atlantic. summation operatorPBDE concentrations (mono- to hexa-BDEs) detected in blubber samples (n=42) ranged from 80 to 25720 ng g(-1)lw, (overall mean 2403+/-5406 ng g(-1)lw). By age, mean summation operatorPBDE concentrations were: 364...

Polybrominated diphenyl ethers in UK human milk

24 Fourteen tri-deca polybrominated diphenyl ethers (PBDEs) were investigated in 35 human 25 milk samples from Birmingham, UK. While none of the hepta-nona BDEs (the main 26 components of the OctaBDE technical mixture) were above the limit of quantitation (LOQ); 27 BDE-47 (average concentration = 3.3 ng g lipid weight (lw)) was quantified in all samples 28 contributing 34-74% to Σtri-hexa BDEs ...
