“…It can be concluded from these data that PFE is appropriate for the quantitative extraction and determination of PCB congeners and chlorinated pesticides in a complex biological matrix such as fish tissue. Low Soxhlet extraction efficiencies relative to PFE extraction have been observed for PAHs associated with combustion samples [39] indicating the extraction method can be matrix dependent in some instances.…”

The concentrations of a wide range of polychlorinated biphenyl congeners (PCBs) and chlorinated pesticides in a fish tissue Standard Reference Material (SRM) have been determined using multiple methods of analysis. This material, SRM 1946, Lake Superior Fish Tissue, was recently issued by the National Institute of Standards and Technology (NIST) and complements a suite of marine environmental natural-matrix SRMs that are currently available from NIST for the determination of organic contaminants such as aliphatic hydrocarbons, polycyclic aromatic hydrocarbons (PAHs), PCBs, and chlorinated pesticides. SRM 1946 is a fresh tissue homogenate (frozen) prepared from filleted adult lake trout (Salvelinus namaycush namaycush) collected from the Apostle Islands region of Lake Superior. SRM 1946 has certified and reference concentrations for PCB congeners, including the three non- ortho PCB congeners, and chlorinated pesticides. Certified concentrations are available for 30 PCB congeners and 15 chlorinated pesticides. Reference concentrations are available for 12 PCB congeners and 2 chlorinated pesticides. In addition, SRM 1946 is characterized for additional chemical constituents and properties: fatty acids, extractable fat, methylmercury, total mercury, selected trace elements, proximates, and caloric content. The characterization of chlorinated compounds is described in this paper with an emphasis on the approach used for the certification of the concentrations of PCB congeners and chlorinated pesticides. The PCB congener and chlorinated pesticide data are also compared to concentrations in other marine natural-matrix reference materials available from NIST (fish oil, mussel tissue, whale blubber, and a second fresh frozen fish tissue homogenate prepared from filleted adult lake trout collected from Lake Michigan) and from other organizations such as the National Research Council Canada (ground whole carp), the International Atomic Energy Agency (fish homogenate), and the European Commission Joint Research Centre [fish oils (cod and mackerel) and mussel tissue].

“…The first set of results in this study was obtained using the 5% phenyl methylpolysiloxane column that has typically been used for PAH and nitro-PAH measurements. Recently, the 50% phenyl methylpolysiloxane has been shown to provide better selectivity for the separation of several critical pairs of PAH isomers [26,33], and therefore this stationary phase was evaluated for the separation of nitro-PAH isomers, particularly the 2-nitrofluoranthene and the 3-nitrofluoranthene, which coelute on the 5% phenyl methylpolysiloxane phase. A detailed comparison and discussion of the 50% phenyl and 5% phenyl methylpolysiloxane phases for the separation of nitro-PAH isomers is described elsewhere [32].…”

Gas chromatography/mass spectrometry (GC/MS) with negative ion chemical ionization (NICI) detection was utilized for quantitative determination of nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) in diesel particulate-related standard reference materials (SRMs). Prior to GC/MS analysis, isolation of the nitro-PAHs from the complex diesel particulate extract was accomplished using solid phase extraction (SPE) and normal-phase liquid chromatographic (LC) fractionation using an amino/cyano stationary phase. Concentrations of eight to ten mononitro-PAHs and three dinitropyrenes were determined in three diesel particulate-related SRMs: SRM 1650a Diesel Particulate Matter, SRM 1975 Diesel Particulate Extract, and SRM 2975 Diesel Particulate Matter (Industrial Forklift). The results from GC/MS NICI using two different columns (5% phenyl methylpolysiloxane and 50% phenyl methylpolysiloxane) were compared to each other and to results from two other laboratories for selected nitro-PAHs. 1-Nitropyrene was the most abundant nitro-PAHs in each of the diesel particulate SRMs (19.8+/-1.1 micro g g(-1) particle in SRM 1650a and 33.1+/-0.6 micro g g(-1) particle in SRM 2975). Three dinitropyrene isomers were measured in SRM 1975 at 0.5-1.4 micro g g(-1) extract and in SRM 2975 at 1-3 micro g g(-1) particle.

“…SRM 1650b was analyzed to confirm that the bulk diesel particulate matter was unchanged since SRM 1650 and SRM 1650a were characterized. SRM 1650b complements two other diesel particulaterelated SRMs that are currently available (Poster et al, 2003c(Poster et al, , 1999a: SRM 2975, Diesel Particulate Matter (Industrial Forklift) and SRM 1975, Diesel Particulate Extract, which is a dichloromethane extract of the same material used to prepare SRM 2975. Selected PAH concentrations in SRM 1650b are presented in Table 3.…”
