| Abstract |
A liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the simultaneous determination of bisphenol A (BPA) and tetrabromobisphenol A (TBBPA) in different seafood samples was developed and validated. Sample preparation was based on a quick, easy, cheap, effective, rugged, and safe (QuEChERS)-based procedure through an extraction of target analytes with acidified acetonitrile (MeCN) added with inorganic salts (MgSO4, NaCl) followed by a liquid-liquid extraction (LLE) using hexane-tertbutylmethyl ether/hexane-benzene to eliminate matrix co-extracts. The developed method promotes a better removal of interferences than that achieved with the classic QuEChERS procedure. The method was validated following the guidelines of the European Union (EU) for relevant seafood matrices such as fish, mussel, and seaweed. Accuracy (81 % average of recovery), reproducibility (12 % average relative standard deviation for both intra-day and inter-day repeatability), and sensitivity for the target analytes (method detection limits of 0.07 ng/g wet weight (ww) and 0.06 ng/g ww for BPA and TBBPA, respectively) were evaluated for all the matrices studied. Graphical Abstract Simultaneous analysis of TBBPA and BPA in seaweeds, mussels and fish. |

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 09 January 2017.
All research outputs
#19,942,887
of 25,371,288 outputs
Outputs from Analytical & Bioanalytical Chemistry
#6,060
of 9,618 outputs
Outputs of similar age
#233,121
of 319,604 outputs
Outputs of similar age from Analytical & Bioanalytical Chemistry
#68
of 190 outputs
Altmetric has tracked 25,371,288 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% of other outputs scored the same or lower than it.
So far Altmetric has tracked 9,618 research outputs from this source. They receive a mean Attention Score of 3.1. This one is in the 31st percentile – i.e., 31% 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 319,604 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 23rd percentile – i.e., 23% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 190 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 56% of its contemporaries.
