	abstract = {Two species of marine clam, Mya arenaria and Protothaca staminea, were exposed to pyrene and 1-hydroxypyrene in small glass aquaria. After 10 days of exposure the clams were sacrificed, and both clam tissue and seawater were assayed for pyrene metabolites by using HPLC, fluorescence spectroscopy, HPLC-ESI-MS, GC-MS and H-1-NMR spectrometry. 1-Pyrenol-1-hydrogensulfate (pyrene-1-sulfate) was identified as the major water soluble metabolite formed from both pyrene and 1-hydroxypyrene by both species of clam. 1-Hydroxypyrene was identified as a minor metabolite of pyrene, and pyrenediol-hydrogen sulfate was identified as a minor metabolite of 1-hydroxypyrene.

	abstract = {Ion/molecule reactions between fluorocarbon cations, generated from perfluorotributylamine (FC43), and polycyclic aromatic hydrocarbons (PAHs) were carried out in a quadrupole ion trap by mass isolating individual types of FC43 ions (R+) and reacting them with PAHs eluting from a GC column. The observed products resulting from these reactions consisted of [M + R](+) adducts and [M + R - nHF](+) (n = 1,2) elimination products. The relative abundance of these products was found to vary between different PAH structural isomers, such as anthracene and phenanthrene, thus enabling isomer differentiation. Of particular interest was the reactivity of the C3F5+ cation because this species yielded the most abundant and diverse reaction chemistry. Formation of adducts versus molecular ions appears to be strongly influenced by the ionization energy (IE) of the PAHs. Using this ion/molecule reaction technique several PAH isomers, present in a PAH contaminated environmental sediment extract, could be identified.

	abstract = {Ion-molecule reactions between the cations CH3CHF+ and CH3CF2+ generated from 1,1-difluoroethane and gas chromatographic eluents from a sediment extract containing polycyclic aromatic hydrocarbons (PAHs) were used to differentiate goups of PAH structural isomers, Formation of specific adducts led to characteristic mass spectra for the different isomers. Differences in the ion chromatograms for M+, MH+, [M+CH3CHF](+), [M +CH3CHF-HF](+), [M+CH(3)CF2](+) and [M+CH3CF2-HF](+) (M=PAH molecule) allowed the resolution of co-eluting isomers. As the ratio of yields of adducts was not changed by methyl substitution, it was possible to differentiate and quantitate alkylated PAHs for which standards were not available, By performing a series of transformations between the ion chromatograms of the most characteristic;adducts, information on individual isomer groups could he deconvoluted from complex clusters of isomers. This ion trap/chemical ionization technique displayed calibration curse parameters similar to those for electron ionization analysis and limits of detection of 170 pg in the sediment extract.

	abstract = {GC/MS and GC/MS/MS in a quadrupole ion trap were used to analyze for anthraquinone, alkyl anthraquinones, benz[a]anthracene-7,12-dione and 9-fluoranone in a sediment obtained from an aluminum smelter settling pond contaminated with polycyclic aromatic hydrocarbons. By standard GC/MS analysis many of these target compounds were either undetectable or their confirmation uncertain because of matrix interferences. Detection and identification were greatly improved by using GC/MS/MS. GC/MS/MS analyses were performed by selecting the molecular ion (M) of a target compound and fragmenting it via collision induced dissociation (CID) to yield product ions corresponding to loss of CO for unsubstituted compounds or CO plus CH3 for alkylated compounds. The CID conditions were optimized using anthraquinone and 2-methylanthraquinone standards by varying the CID excitation energy and RF storage levels to yield optimum amounts of fragment ions. CID experiments were performed using both resonant and non-resonant wave forms. Although both excitation techniques gave comparable results for the removal of matrix interferences, non-resonant excitation provided more characteristic spectra for the alkylated anthraquinones. Monitoring of secondary fragmentation products, such as M-2CO, provided greater discrimination from matrix interferences than the use of primary fragmentation products, such as M-CO.

	abstract = {Surficial marine sediments from 20 sites within the Kitimat fjord system were analyzed for polycyclic aromatic hydrocarbons (PAHs), Levels of the sum of the 16 USEPA priority pollutant PAHs varied from below detection limits (ca, 1 mu g . g(-1)) to over 10 000 mu g . g(-1). Sediment PAH levels were highest in the immediate vicinity of a large aluminum smelter at the head of Kitimat Arm, and declined rapidly with increasing distance from the smelter. However, even at some of the more distant sites which are geographically isolated from the smelter PAH levels were elevated. The PAH distribution in the fjord system is consistent with a combination of aeolian and fluvial transport of PAHs emitted by the aluminum smelter at the head of Kitimat Arm. The mixture of PAHs present was qualitatively similar in all samples analyzed, including those from the distant sites. All aspects of the PAH composition are consistent with combustion generated PAHs. A correlation between PAH levels and sediment organic carbon was observed; however, this was only significant for highly contaminated sites in the harbor. This probably reflects the high organic content of particulate emissions from the smelter, rather than equilibrium partitioning of PAHs to sediment organic carbon within the harbor itself.},
