From the fluorescence analysis of PAC-doped model oils on alumina, quartz sand and soil surfaces LIF intensity/concentration-relationships (calibration curves) were obtained. It was found that LIF measurements directly for soil surfaces allow the in-situ analysis of PAC contaminations in environmentally relevant concentration ranges. However, the LIF signals measured cannot directly be related to photophysical parameters of the PAC in solution. Also reported are results of preliminary investigations of the long-term behavior and the depth profile of perylene or fluoranthene LIF signals from surfaces reflecting mass transport and sorption processes.
