Ambient concentrations and gas/particle partitioning of Polybrominated Diphenyl Ethers (PBDEs) were investigated in a industrial, a traffic and a background site in the urban agglomeration of Thessaloniki, northern Greece. Atmospheric (gas+particle) concentrations of ∑12PBDE at industrial site were higher than those observed at urban-traffic and urban-background sites. In industrial site, mean ...

Polybrominated diphenyl ethers (PBDEs) are a class of flame retardants historically used in textiles, furniture, and electronic products. Recent studies have documented widespread PBDE exposure to humans, with higher levels measured in children than adults. We analyzed 10 tri- to hepta-BDE congener levels in blood collected from 7-year old Mexican-American children living in an agriculture comm...

Emerging brominated flame retardants (eBFRs) other than polybrominated diphenyl ethers (PBDEs), polybrominated biphenyls (PBBs) and their derivatives in foods have been in focus in recent years due to their increasing production volumes, indefinite information on toxicities and the lack of data on occurrence in environments, foods as well as humans. In this study, gas chromatography was coupled...

An improved derivatization protocol for the simultaneous determination of alkylphenol ethoxylates and brominated flame retardants with heptafluorobutyric anhydride under triethylamine amine base was investigated. The derivatization reaction was completed in 30 min at 50 °C using hexane as solvent. Under these conditions, it was observed that alkylphenol ethoxylates and tetrabromobisphenol A wer...

Increased interest in the fate, transport and toxicity of polybrominated diphenyl ethers (PBDEs) over the past few years has led to a variety of studies reporting different methods of analysis for these persistent organic pollutants. Because PBDEs encompass a range of vapor pressures, molecular weights and degrees of bromine substitution, various analytical methods can lead to discrimination of...

Atmospheric concentrations of polybrominated diphenyl ethers (PBDEs), a group of industrial chemicals widely used as flame retardants were measured over the Indian Ocean and represent the first comprehensive data of atmospheric contaminations of PBDEs over the open ocean. Air back trajectory analysis shows that PBDEs have great potential for long-range atmospheric transport to remote regions of...

Using a system of whole-embryo culture, the effect of polybrominated biphenyls (PBB) was investigated on the rates of DNA, RNA, and protein accumulation in rat embryos. Embryos were isolated on the 10th gestational day (sperm day = Day 0) either 4 or 24 hr after maternal administration. The cultivation period was for 24 or 42 hr. DNA, RNA, and protein accumulation rates were not affected by a 4...
