Paper Abstract

Quantitative analysis of unknown PAH contaminated soil samples have been performed using laser-induced fluorescence (LIF) spectroscopy and strategies for a safe application of calibration routines under field conditions have been developed. Influences of varying matrix properties have been investigated using LIF and diffuse reflectance (DR) spectroscopy. A petroleum hydrocarbon contaminated former military site has been investigated and the results from the on-site LIF measurements are compared to the results of additional laboratory analysis. A three dimensional dataset of analyte concentrations has been prepared and extent, distribution and origin of the contamination are discussed. A fiber optical probe for in situ LIF-investigations in the subsurface has been developed. The probe has been tested in investigations of soil columns and within in situ measurements at a former gas work site.
