Abstract In this paper we show that oxygenated polycyclic aromatic hydrocarbons (oxy-PAHs) are important cocontaminants that should be taken into account during risk assessment and remediation of sites with high levels of PAHs. The presented data, which have been collected both from our own research and the published literature, demonstrate that oxy-PAHs are abundant but neglected contaminants at these sites. The oxy-PAHs show relatively high persistency and because they are formed through… 

Oxy-PAHs: occurrence in the environment and potential genotoxic/mutagenic risk assessment for human health

This review has compiled exhaustively all the data available on the sources, the fate, and the occurrence of oxy-PAHs focusing on the most ubiquitous ones in the environment, ie PAKs and PAQs and proposes to develop biomarkers of exposure and/or risk for these compounds, for example by quantification of DNA adducts.

The Parallel Transformations of Polycyclic Aromatic Hydrocarbons in the Body and in the Atmosphere

Background. Polycyclic aromatic hydrocarbons (PAHs) emitted from combustion sources are known to be mutagenic, with more potent species also being carcinogenic. Previous studies show that PAHs can

Evaluation of Polycyclic Aromatic Hydrocarbons Using Analytical Methods, Toxicology, and Risk Assessment Research: Seafood Safety after a Petroleum Spill as an Example

The increasing ability of contemporary analytical methods to distinguish not only different chemical structures among PAHs but also their concentrations in environmental media is discussed, and issues that are emerging in the PAH risk assessment process are identified.

Chemical and bioanalytical characterisation of PAHs in risk assessment of remediated PAH-contaminated soils

Comparison of the results showed that the bioassay-determined toxicity in the remediated soil samples could only be explained to a minor extent by the concentrations of the 16 priority PAHs.



Degradation and formation of polycyclic aromatic compounds during bioslurry treatment of an aged gasworks soil

Investigation of the relative degradation rates of polycyclic aromatic compounds in contaminated soil found that low molecular weight PAHs and heterocyclics were degraded faster than the high molecular weight compounds, while oxy-PAHs degraded more slowly than the parent compounds, suggesting that they were formed during the treatment or that they are more persistent.

An up-to-date source of photochemical reaction, photo-transformation, and phototoxicity of PAHs and their oxygenated, nitrated, halogenated, and amino substituted derivatives on a molecular basis is provided.

Toxicity and genotoxicity enhancement during polycyclic aromatic hydrocarbons biodegradation

It is concluded that when degradation is incomplete, the potential exists for toxicity and genotoxicity enhancement, with the latter hazard not always predictable by short-term toxicity assays.

Mutagenic hazards of complex polycyclic aromatic hydrocarbon mixtures in contaminated soil

Estimates of excess lifetime cancer risk associated with the nondietary ingestion of the PAH-contaminated soils studied here indicate that a traditional risk assessment model based on identified priority PAHs and an assumption of additivity generally underestimates the riskassociated with the nonpolar soil fractions (in comparison to bioassay-derived risk estimates).

Sources of PAHs in the Environment

PAHs are primarily emitted by anthropogenic activities, and although some natural and secondary sources of these contaminants are discussed, the focus of this chapter is the major primary sources to
