Modalités de contamination du ray-grass par les éléments du groupe platine et les hydrocarbures aromatiques polycycliques à proximité des voies routières

Abstract : Our thesis work concerned the methods of PGE and PAH deposits on fodder using a bio-accumulator (ryegrass). The deposit kinetics of PGE and PAH on ryegrass exposed in the vicinity of a highway showed that the main part of the contamination is carried out during the first weeks of exposure, and also that these contaminants remain fixed on the ryegrass at least five weeks after its removal from the highway. The study of the traffic conditions influence showed a weak impact of the highway on the ryegrass contamination by PGE and PAH compared to a rural road, suggesting that the PGE and PAH deposits on the ryegrass are much more related to the emission properties from the vehicles than to the number of vehicles. The spatialization of the fodder exposure in PGE and PAH on a fodder plot scale revealed a significant reduction of the Pd, Rh and PAH concentrations of the ryegrass with the distance of the emission source.
