| Abstract |
Polybrominated diphenyl ethers (PBDEs) are a class of flame retardant registered as UN POPs due to their persistence in the environment, bioaccumulation potential and toxicity. Replacement novel brominated flame retardants (NBFRs) have exhibited similar health hazards and environmental distribution, becoming recognized as significant contaminants. This work describes the development and validation of a sensitive and reliable method for the simultaneous quantitation of PBDEs and NBFRs in environmental soil samples using selective pressurized liquid extraction (S-PLE) and gas chromatography coupled to triple quadrupole mass spectrometry (GC-(EI)-MS/MS). Under optimal conditions, extraction of eight PBDEs (-28, -47, -99, -100, -153, -154, -183 and -209) and five NBFRs; pentabromotoluene (PBT), pentabromoethylbenzene (PBEB), hexabromobenzene (HBB), 2-ethylhexyl-2,3,4,5-tetrabromobenzoate (EH-TBB) and bis(2,4,6-tribromophenoxy)ethane (BTBPE) was performed at 100°C and 1500psi using a 1:1 mixture of hexane and dichloromethane. The method utilized 33mL capacity PLE cells containing, from bottom to top, a single cellulose filter, 3g activated Florisil, 6g acid silica (10% w/w), 3g Na2SO4, another cellulose filter, 2g activated copper powder and 3g soil sample dispersed in 2g Na2SO4 and 1g of Hydromatrix. The method was evaluated by repeated extraction and analysis of all analytes from 3g soil at three spike concentrations. Good recoveries were observed for most analytes at each of the spiking levels with RSD values generally below 20%. MDLs ranged from 0.01 to 4.8ng/g dw for PBDEs and 0.01-0.55ng/g dw for NBFRs. The described one-step combined extraction and cleanup method reduces sample processing times compared with traditional procedures, while delivering comparable analytical performance. The method was successfully applied to environmental soil samples (n=5), detecting PBDEs in each sample and providing the first account of NBFR contamination in Australian soils. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 08 October 2016.
All research outputs
#20,656,820
of 25,374,647 outputs
Outputs from Journal of Chromatography A
#9,536
of 11,800 outputs
Outputs of similar age
#271,987
of 355,758 outputs
Outputs of similar age from Journal of Chromatography A
#34
of 50 outputs
Altmetric has tracked 25,374,647 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 11,800 research outputs from this source. They receive a mean Attention Score of 3.4. This one is in the 8th percentile – i.e., 8% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 355,758 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 50 others from the same source and published within six weeks on either side of this one. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
