“…The optimized method was used to detect PBDEs in Belgian indoor dusts. The obtained BDE 209 concentrations (8–292 ng/g dw) are in the same range or lower than those in dusts from other European countries (Dirtu et al, 2008).…”

This review summarized the applications of mass spectrometric techniques for the analysis of the important flame retardants polybrominated diphenyl ethers (PBDEs) to understand the environmental sources, fate and toxicity of PBDEs that were briefly discussed to give a general idea for the need of analytical methodologies. Specific performance of various mass spectrometers hyphenated with, for example, gas chromatograph, liquid chromatograph, and inductively coupled plasma (GC/MS, LC/MS, and ICP/MS, respectively) for the analysis of PBDEs was compared with an objective to present the information on the evolution of MS techniques for determining PBDEs in environmental and human samples. GC/electron capture negative ionization quadrupole MS (GC/NCI qMS), GC/high resolution MS (GC/HRMS) and GC ion trap MS (GC/ITMS) are most commonly used MS techniques for the determination of PBDEs. New analytical technologies such as fast tandem GC/MS and LC/MS become available to improve analyses of higher PBDEs. The development and application of the tandem MS techniques have helped to understand environmental fate and transformations of PBDEs of which abiotic and biotic degradation of decaBDE is thought to be one major source of Br(1-9)BDEs present in the environment in addition to direct loading from commercial mixtures. MS-based proteomics will offer an insight into the molecular mechanisms of toxicity and potential developmental and neurotoxicity of PBDEs.

“…16,17 However, generally, the elution temperatures of such compounds in GC systems are very close or even higher than the degradation temperatures reported for brominated FRs. 18 As a consequence, if their degradation into GC systems is not fully considered, this generates an increased uncertainty for their quantification and therefore errors occur when estimating the human exposure to such compounds. Even if the thermal degradation of such compounds due to instrumental conditions applied for their identification and quantification is reported in scientific literature in the field, 5 there are no systematic studies by proper thermosanalytical methods to report on their behavior.…”

This study aims to investigate the thermal degradation behavior of decabrominated diphenyl ether (BDE 209), a flame retardant (FR) which accounts for more than 90% of the total polybrominated diphenyl ethers reported for indoor dust samples collected from Eastern Romania. Simultaneous TG/DTA was applied under various heating rate and atmospheres. The results of this study showed that BDE 209 undergoes thermal degradation in a single step, regardless of the heating rate or atmosphere, with an initial degradation temperature between 297 and 330 0 C, depending on the heating rate, and a partial overlapping of melting and thermal degradation in the initial stages which might suggest that the common degradation noticed for the higher brominated FRs analysis might also occur during sample preparation or during injection of the extracts in the GC systems and not necessarily during column elution. The main findings of this research were aimed at designing proper GC analytical methods for the selected halogenated contaminants.

“…Problems reported in the analysis of BDE-209 cover its (partial) degradation in both the presence of an organic hydrogen donor and UV-light [14][15][16][17][18][19][20]. In addition, BDE-209 may be adsorbed onto glassware due to its low solubility in most organic solvents [11,12], and its thermal instability may force the degradation in hot and dirty GC injection ports as well as on GC columns [9,21,22]. These issues were underlined in several interlaboratory studies which frequently have resulted in rather high standard deviations of up to 105% [8,12,23,24].…”
