Certification of Polycyclic Aromatic Hydrocarbons in Mussel Tissue and Air Particulate Standard Reference Materials (SRMs)

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). SRM 1649, Urban Dust/Organics, which was issued in 1982, has been reanalyzed to provide certified and noncertified concentrations for 35 PAHs. Both materials were analyzed using four different analytical techniques based on gas chromatography/mass spectrometry on different stationary phases and on reversed-phase liquid chromatography with fluorescence detection.
