“…In addition to the complexity of the target compounds, matrix interferences in environmental samples can be substantial (e.g. O'Connell et al, 2013;Pojana and Marcomini, 2007). Solid and liquid environmental matrices contain additional macromolecules, humic substances, salts, and other interfering compounds.…”

Over the past 20 years, a growing body of research has raised concerns about the toxicity, fate, and transport of oxygenated transformation products of polycyclic aromatic hydrocarbons. Research targeting these diverse compounds in soil and water systems has been challenged by a lack of standard analytical techniques and suitable reference materials. However, recent efforts towards the consolidation of traditional analytical techniques as well as the development of novel approaches to improve sample preparation and hyphenated instrumental techniques show promise. This review discusses progress and challenges for both trends in analytical method development, and makes recommendations for supporting oxygenated PAH research.

“…The measurement of intermediates of PAH degradation under field conditions in soil will be useful for the study of natural attenuation of PAHs, for monitoring of remediation processes, and for source apportionment (McKinney et al, 1999; Lundstedt et al, 2007; Reineke et al, 2007). The available studies of OPAH concentrations in the environment focus on atmospheric samples: aerosols and gas phase (Allen et al, 1997; Albinet et al, 2006; Lintelmann et al, 2006; Delhomme et al, 2008), waste water (Pojana and Marcomini, 2007), sediments (McKinney et al, 1999), sewage sludge (Bodzek et al, 1997), human and animal fluids (Smith et al, 2002; Grova et al, 2005), and fish biles (Johnson‐Restrepo et al, 2008). The few studies of soils are limited to highly contaminated soils (creosote/gasworks/wood impregnation/coke production sites) or spiked soils (at concentration levels of μg g −1 to mg g −1 ranges) used for recovery and degradation studies (Wischmann et al, 1996; Meyer et al, 1999; Lundstedt et al, 2006a).…”

Although polycyclic aromatic hydrocarbons (PAHs) have been extensively studied, the knowledge of their oxygen-containing derivatives and metabolites (OPAHs) in soils is limited. We modified and tested an existing analytical protocol involving pressurized liquid extraction of soil followed by fractionation of target compounds into PAHs and OPAHs on a silica gel column and gas chromatography/ mass spectrometry-based separation and quantification. Polycyclic aromatic hydrocarbons and carbonyl-OPAHs were quantified directly after separation on silica gel columns, and hydroxyl/carboxyl-OPAHs were quantified after silylation with N,O-bis(trimethylsilyl)trifluoroacetamide. Recoveries between 78 and 97% (relative standard deviation [RSD], 5-12%) were obtained for six carbonyl-OPAHs, whereas 1,2-acenaphthenequinone and 1,4-naphthoquinone showed lower recoveries of 34 and 44% (RSD, 19 and 28%, respectively). Five hydroxyl/carboxyl-OPAHs had recoveries between 36 and 70% (RSD, 13-46%), six others had between 2 and 7% (RSD, 8-25%), and nine were lost in sample preparation. Limits of detection ranged from 0.1 to 1.6 ng g(-1) for OPAHs and from 0.01 to 0.56 ng g(-1) for PAHs. The protocol was applied to soils from a former gasworks site, Berlin, an urban soil from Mainz, both in Germany, and a forest soil from near Manaus, Brazil. The sums of 34 PAH concentrations were 107,000, 3505, and 21 ng g(-1); those of seven carbonyl-OPAHs were 15,690, 170, and 7 ng g(-1); and those of 11 hydroxyl/carboxyl-OPAHs 518, 36, and 16 ng g(-1) for Berlin, Mainz, and Manaus soils, respectively. Several OPAHs were present at concentrations higher than or equal to their parent PAHs, demonstrating the importance of OPAH measurement for the assessment of PAH-related environmental risks.

“…Higher temperature, ultra violet radiation and chemicals such as ozone used in some STP can oxidize these reactive molecules, while enzymes present in micro and macro-organisms also produce oxidation products (11,12). Since there are common PAH oxidation forms produced through different pathways, there is also an interest in determining the presence of PAH transformation products in environmental compartments, especially near STP (13,14). These chemicals represent another class of emerging contaminants arising from known priority pollutants.…”

Eastern mud snails were exposed to pyrene (PY) and 1-hydroxypyrene (PYOH) spiked individually in sediment. Animals were examined for the bioaccumulation of parent compound and the presence of biotransformation products in soft tissue extracts after 3 days of exposure. Single and double oxidation products along with sulphate conjugates were detected in animals from both exposures, with traces of mono-glucuronide. The major phase I and II products were 1-hydroxypyrene (PYOH) and pyrene-1-sulphate (PYOS). Biotransformation was more efficient at low levels of PY or PYOH exposure and bioaccumulation more substantial at higher dose. Phase I oxidation was more efficient in fall exposed snails and phase II conjugation in the summer. Stressed animals were seen in the fall and analyzed separately from healthy ones. Their level of abundant metabolites was thrice that of non-stressed snails. The present data can be compared to a published study where snails were exposed to spiked food that was consumed within minutes. In that earlier work, stressed snails were associated with five times the level of metabolites than unaffected animals. Therefore, a longer contaminants' uptake time led to observing a lower excess of metabolites in soft tissues of impacted snails. PYOH degraded more readily in the snails' native sediments than PY, with intermediates in the catabolism of the compound detectable in sediments 3 days after spiking the media. This study demonstrates the importance of investigating the balance of fates of PAC in biotic and abiotic compartments in order to understand the state of the environment.
