The growth conditions of halophytic species Triglochin maritima and Plantago maritima on tidal zone of western coast of the White Sea were studied. The littoral soils were characterized by medium and slightly saline, poor content of organic substances, manganese, zinc, nickel, lead, and content of natural amounts of iron and copper. Sea water was contaminated with iron (3.8 of MPC) and nickel (55 of MPC), and contained poor of zinc and copper as well as natural level of lead and manganese. The studied plant species actively accumulated metals. For T. maritima the following metal accumulation series was obtained: Ni (3.80) > Fe (2.08) > Cu (1.91) > Zn (1.84) > Pb (1.51) > Mn (1.31) and for P. maritima, Cu (3.29) > Zn (2.81) > Ni (1.57) > Pb (1.30) > Mn (1.21) > Fe (0.97). The roots accumulated 50%–70% of Ni, Cu, Zn, Pb, and Mn. The results show that the test plants can be used in the phytoremediation process of marine territories. |
