Abstract

The application of the Laser Induced Fluorescence (LIF) method in an urban area with oil waste deposited over 30 years shown good results and has proven to be an important tool to be used in tridimensional delimitation of oil residue plumes, specifying in real time and at low cost the region where remediation should be undertaken. Comparing the results obtained by other environmental investigation methods LIF has demonstrated to be efficient in field detection of oil residues as well as oil impregnated soil, independent of the degree of weathering and heterogeneity of spatial distribution. The response to fluorescence was coherent with the type of material that predominates composed of long-chain-hydrocarbons. The method was sensible to detect even thin lenses of residues.
