Method for analyzing soil pollution

A method for analyzing soil contamination by pollutants by way of hyperspectral analysis of reflection and/or photoluminescence, wherein the analysis is carried out using a first item of equipment by illuminating a sample using a light source and by at least one spectral sensor sensitive to a spectrum ranging from thermal infrared to ultraviolet, wherein the method includes:

• a learning sequence comprising analyzing a plurality of reference samples, and recording in a learning database:
• a) the spectral signature of reflection acquired by spectral analysis;
• b) known values of the variables representative of the contaminants present in each of the reference samples;
• and
• c) known values of the variables representative of the substrates of each of the reference samples;
• a sequence for calibrating an item of field analysis equipment with respect to the first item of equipment, the item of field analysis equipment including a light source and a spectral sensor,
• sequences for analyzing a soil sample of a geological site comprising acquiring the reflection and/or photoluminescence signature of the sample using the item of field equipment thus calibrated;
• and
• estimating the characterization of the pollutants by processing the signature by a learning engine exploiting the data from the database established during the learning sequence.
