In this work, a method for the analysis of 24 PAHs in 19 different matrices, including
fish tissues, feeds and feed ingredients, has been developed using gas chromatography
coupled to triple quadrupole tandem mass spectrometry with atmospheric pressure
chemical ionization source (GC-APCI-MS/MS). The method is based on a modification
of the unbuffered QuEChERS method, using freezing as an additional clean-up step and
applying a 20-fold dilution factor to the final extract. The procedure was also tested for
15 pesticides and 7 polychlorinated biphenyl (PCB) congeners in order to widen the
scope of the method.
The excellent sensitivity and selectivity provided by GC-APCI-MS/MS allowed the
dilution of the sample extracts and quantification using calibration with standards in
solvent for all the 19 matrices tested. The developed method was evaluated at 2, 5 and
50 ng·g-1 spiking levels. LOQs were 2 ng·g-1 for most compounds, and LODs ranged
from 0.5 to 2 ng·g-1.
Analysis of real-world samples revealed the presence of naphthalene, fluorene,
phenanthrene, fluoranthene and pyrene at concentration levels ranging from 4.8 to 187
ng·g-1. No PCBs, DDTs and pesticides were found in fillets from salmon and sea bream. [-]
