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 (I_F), the reflectances (R) of the soils are taken into account. It is demonstrated that using 'normalized' LIF signal intensities I_F/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 I_F/R is shown to be approximately constant. Therefore, the calibration with 'normalized' LIF signal intensities allows the quantification of a contaminant in different soils.
