Paper Abstract

In this paper results of LIF and DR measurements of diesel- fuel contaminated natural and model soils are presented. In order to characterize the influence of soil optical properties on LIF signal intensities (IF), the reflectances (R) of the soils are taken into account. It is demonstrated that using 'normalized' LIF signal intensities IF/R significantly reduced the influence of the variability of the matrices. For various natural and model soils contaminated with 5000 ppm diesel fuel the ratio of IF/R is shown to be approximately constant. Therefore, the calibration with 'normalized' LIF signal intensities allows the quantification of a contaminant in different soils.
