摘要: Abstract A mild, low-temperature analytical approach based on sonication assisted extraction coupled with HPLC electrospray ionization triple quadrupole tandem mass spectrometry has been developed for the simultaneous qualitative and quantitative determination of four Irgarol-related s-triazine species, namely Irgarol-1051, M1, M2 M3, in coastal sediments Green-lipped mussel samples. Mild conditions were necessary preservation thermally unstable M2. The Multiple Reaction Monitoring (MRM) mode detection by ESI-MS/MS enabled reliable identification sensitive those s-triazines. This method was applied to evaluate degree Irgarol-1051 contamination biota environment Hong Kong – one busiest maritime ports world. All species observed all is first time that newly identified M3 are detected tissues.
