The emergent water plants Juncus effusus and Typha latifolia are studied as phytoremediants in constructed wetlands. Degradation of some toxic organic pollutants in the rhizosphere of plants may be followed by biochemical shifts in the surface lipids formation and change in their functions. The total fatty acid composition of surface lipids of these species was studied. An unusual composition of fatty acids and typical heavy isotopic discrimination for C3-plants have been detected. The possible role of some lipid components in the protective functions of plant organism is discussed.
