Lay Summary (English)

Lay summary
The polycyclic aromatic hydrocarbons (PAHs) are well known persistent organic pollutants which can cause harm to ecosystems and humans. Therefore, maximum acceptable PAH concentrations in soils are legaly defined in many countries.The oxygenated polycyclic aromatic hydrocarbons (OPAHs) are either simultaneously produced with PAHs in combustion processes or are derivatives of PAHs resulting from abiotic or biotic transformation of PAHs in the environment. Although it is known that the OPAHs may be even more toxic than corresponding PAHs, little is known about OPAHs in the environment and no regulations of OPAHs in the environment exist. This is partly related to the difficult chemical analysis of these compounds.Our overall goal is to contribute to improved understanding of OPAHs in the environment, particularly in soil which is likely the largest OPAH reservoir. Specifically, we will (i) improve the analytical approach to these compounds in soil, (ii) broaden the small data base of OPAH concentrations in soils to identify the most abundant OPAHs and investigate into the transport of OPAHs through the soil to the groundwater. Furthermore, we aim to (iii) identify OPAHs sources (i.e. primary combustion vs. secondary transformation sources) and finally (iv) determine to which degree OPAHs are produced by transformation of PAHs in soil.Our work will provide new important information about the sources and risks associated with an ubiquitous class of environmental pollutants. The result will allow for deriving political advice to improve environmental monitoring, avoidance of environmental pollution, and the protection of the population against environmental risks.

Abstract

The environmental fate of polycyclic aromatic hydrocarbons (PAHs), a group of persistent organic pollutants produced in all kinds of combustion processes but also partly by biological activity, was subject to intensive research efforts in the past. The reason was the high toxicity of PAHs resulting in the inclusion of PAHs in the list of priority pollutants (e.g.,by the U.S. Environmental Protection Agency). The PAHs are persistent and mainly microbially degraded to a limited degree in the environment and particularly in soil which is the major storage compartment of PAHs. The degradation produces oxygenated PAHs (OPAHs), some of which are known to be more toxic than their parent-PAHs. Some OPAHs are also directly produced simultaneously to PAHs in combustion processes. Unfortunately, there is a scarcity of information about the occurrence, sources and fate of OPAHs in the environment. We therefore propose to investigate the occurrence, sources and fate of OPAHs in soil, which we assume is also the major storage compartment of OPAHs. The proposal includes (i) the further improvement of a GC/MS-based analytical method recently developed by ourselves with the help of gel permeation chromatography (GPC) as additional clean-up step which is particularly necessary for the analysis of organic matter-rich soils, (ii) the determination of OPAH concentrations in differently contaminated soils to broaden our very limited data base and to assess transport processes of OPAHs in soil, (iii) the identification of OPAH sources in soils (combustion vs. abiotic chemical or microbial oxidation) with the help of correlation analysis, specific ratios of compound concentrations and simultaneouscompound-specific dD and d13C determinations and (iv) the study of PAH degradation both in field soils by determining the depth distribution of PAHs in organic layers of forest soils and by conducting degradation experiments in the laboratory. To reach these objectives, we will make use of our soil archive with samples from all over the world (e.g., Slovakia, Brazil,Thailand), collect further samples in Switzerland and Slovakia and conduct incubations of PAH-contaminated soil in the laboratory. The proposed research will be conducted in close cooperation with an internationalconsortium led by the University of Umeå, Sweden (Polar PAC Network) of which we are member. This proposal therefore also aims at establishing the basis for a possible future European Union-funded international research project.
