Suspect screening for bioaccumulative organohalogen compounds in marine fish
The present study performed suspect screening for bioaccumulative organohalogen compounds in wild black sea bream (Acanthopagrus schlegelii) inhabiting Seto Inland Sea by using two-dimensional (2D) gas chromatograph–high resolution time-of-flight mass spectrometer (GC×GC–HRToFMS) and GC–magnetic sector HRMS. Anthropogenic contaminants (e.g., persistent organic pollutants), marine natural products, and unidentified mixed-halogenated compounds (UHCs) were detected on the 2D total ion current chromatogram (2D TICC) of a fish liver sample. Interestingly, UHCs were also found in seawater, sediment, and oysters sampled from the same location as for marine fish. Considering that UHCs have been not produced commercially and not detected in terrestrial environmental and biological matrices, these compounds might be formed in the marine environment.
