Certification of Polycyclic Aromatic Hydrocarbons in a Mussel Tissue Standard Reference Material (SRM)

Abstract
Standard Reference Material (SRM) 1974a, Organics in Mussel Tissue (Mytilus edulis), has been issued with certified and noncertified concentrations for 33 polycyclic aromatic hydrocarbons (PAHs). The mussel tissue material was analyzed using four different analytical techniques based on gas chromatography/mass spectrometry (GC/MS) on different stationary phases and on reversed-phase liquid chromatography with fluorescence detection. The results from the different analytical techniques were combined to provide certified concentrations for 15 PAHs with relative uncertainties typically between 4% and 11%.
