Mobilisation of PAHs in Soils - Analytical Characterisation and Elucidation of Fundamental Transport and Degradation Processes
Abstract
The aim of this project is the investigation and elucidation of two major processes taking place during soil-contaminant-interaction: on the one hand fundamental mechanisms of PAH-mobilization and on the other hand potential limitations of PAH-degradation. This easily mobilized (i.e. available) fraction of a contamination originates from contaminants that desorb from soil to the water phase. In contrast to the available fraction, the non-mobilized fraction is irreversibly stuck to the soil. For the estimation of risk that arises from a contamination, it is crucial to determine this easily mobilized contaminant fraction, because only the available fraction can cause harm to humans or the environment. The determination of this toxicologically relevant contaminant concentration will be of high interest for future investigation methods in contaminant land management. New conceptual models for the assessment of the easily mobilized fraction are therefore highly recommended. The amount of the easily mobilized PAH fraction in a contaminated soil or similar materials is strongly dependent on the interaction of contaminants and soil particles. In the course of this project the influence of this interaction on various processes such as binding and release as well as transport of contaminants is explored. New analytical tools are tested for the estimation of the easily mobilized PAH-fraction; for the investigation of transport processes soil columns will be used. Due to the findings of the research work, a better understanding of the behaviour of contaminants in the environment should be achieved in future.
