Development of an analytical method for the determination of polybrominated diphenyl ethers in mussels and fish by gas chromatography—Inductively coupled plasma mass spectrometry

摘要

Highlights?Analytical procedure for the determination of PBDEs in fish and mussles was developed.?PBDEs were extracted with TMAH and addition of Tris-citrate buffer and iso-octane.?Concentrations of PBDEs in the organic phase (iso-octane) were determined by GC-ICP-MS.?The procedure developed is simple, accurate, repeatable, reproducible and sensitive.?In fish and mussel samples BDE 47, BDE 100 and BDE 99 were commonly detected.AbstractSix congeners of polybrominated diphenyl ethers (PBDEs): BDE 28, BDE 47, BDE 99, BDE 100, BDE 153 and BDE 154, were determined by a reliable and sensitive analytical method based on gas chromatography coupled to inductively coupled plasma mass spectrometry (GC-ICP-MS) in mussel and fish tissue samples. For their extraction, 30min of ultrasound-assisted extraction w
