Serum concentrations of polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyl (PBB) in the United States population: 2003-2004.
Polybrominated diphenyl ethers (PBDEs) and 2,2',4,4',5,5'-hexabromobiphenyl (BB-153) are chemicals known as brominated flame retardants. We have assessed the exposure status of the United States population to PBDEs and BB-153 and explored associations with demographic information, including participants' age, sex, and race/ethnicity. A total of 2,062 serum samples, from participants in the Nati...
متن کاملDevelopment of analytical procedures for the simultaneous determination of tri- to heptabrominated diphenyl ethers and hexabrominated biphenyl (BB 153) in sediment samples
A simple analytical procedure was developed for simultaneous determination of trace levels of trito hepta-BDEs as well as 2,2′,4,4′,5,5′-hexabromobiphenyl (BB 153). The mechanical shaking extraction technique for the isolation of target analytes was optimised. Different extraction solvent combinations were tested under different extraction time periods of 3, 6, 12 and 16 h. The n-hexane:acetone...
متن کاملA Fluorescence-Based Method for Rapid and Direct Determination of Polybrominated Diphenyl Ethers in Water
A new method was developed for rapid and direct measurement of polybrominated diphenyl ethers (PBDEs) in aqueous samples using fluorescence spectroscopy. The fluorescence spectra of tri- to deca-BDE (BDE 28, 47, 99, 153, 190, and 209) commonly found in environment were measured at variable emission and excitation wavelengths. The results revealed that the PBDEs have distinct fluorescence spectr...
متن کاملEmerging Contaminants – Investigating Brominated Flame Retardant Levels in Soil and Sediment from Fiji Islands
No scientific data is available on emerging contaminants like brominated flame retardant (BFRs) including polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyl (BB 153) levels in the abiotic environment of Fiji Islands. Concentrations of PBDEs and BB 153 were determined in soil and sediment from various land-use types from Fiji Islands. Generally, total concentrations of PBDEs and ...
متن کاملDevelopment of a magnetic particle immunoassay for polybrominated diphenyl ethers and application to environmental and food matrices.
A sensitive magnetic particle enzyme-linked immunoassay (ELISA) was developed to analyze polybrominated diphenyl ethers (PBDEs) in water, milk, fish, and soil samples. The assay was rapid and can be used to analyze fifty samples in about 1h after sample cleanup. The assay has a limit of detection (LOD) below 0.1 ppb towards the following brominated diphenyl ether (BDE) congeners: BDE-47, BDE-99...
