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.
