Abstract
The aim of this in situ study was to investigate the fatty acid FA composition and content in roots and shoots of Lolium perenne and Trifolium repens grown under heavy metal stress Cd Pb Zn The composition of FA was quite similar for the two plants and the two organs main FA were palmitic acid C160 oleic acid C181 linoleic acid C182 and linolenic acid C183 For both plants the major FA that characterized the roots was C182 whereas C183 was the prominent FA in shoots For the first sampling S1 in the roots of L perenne and T repens polyunsaturated fatty acids PUFA were affected by metal contamination while in the second sampling S2 PUFA were affected in the shoots of the two plants This alteration of PUFA was well correlated with the bioaccumulation factor of metals which decreased in roots and increased in shoots with the time Moreover a positive correlation was found between the PUFA decrease and the malondialdehyde MDA content indicating the occurrence of a lipid peroxidation induced by the metal stressThe authors wish to thank the Etablissement Public Foncier NordPas de Calais and the industrial partners APINOR Ltd EDF Surchiste for the settlement of the experimental site and the ADEME for providing financial support We also thank the Dr Fabrice Cazier from the “Centre Commun de Mesures“ of the Université du Littoral Côte d’Opale ULCO for his very helpful technical and scientist assistance in the determination of metal concentrations
