Аннотация:The accumulations of iron in the halophytic species Triglochin maritima L., Plantago maritima L.,Aster tripolium L., and Zostera marina L. were studied. Littoral soils are not contaminated with iron (6–16 g/kg). Seawater, on the contrary, contains high concentrations of iron (0.04–0.32 mg/l). Halophytes accumulateiron to very high values (6.49–71.63 g/kg), and 93% of this metal is found in rhizomes. The reasonsfor this phenomenon are discussed. Halophytes of the littoral zone of the White Sea are involved in the biogeochemicaliron cycle as the main fixation sites of iron in the “coast–sea” system. They have phytoremediationpotential on coastal territories.
