Abstract: The authors have assessed the efficiency of phyto-treatment facilities of JSC “Karelsky Okatysh” located in the Republic of Karelia, and have found out insufficient degree of wastewater treatment for the main metal pollutants (Fe, Mn and Ni). Among the plants used at phytoremediation facilities, the ability to accumulate the specified metals has been revealed in marsh cinquefoil and broadleaf cattail (Comarum palustre and Typha latifolia). The bioaccumulation coefficients for plants sampled from phytomats are the following: BAFFe = 5860, BAFMn = 13764, BAFNi = 1242 and BAFFe = 5150, BAFMn = 19587, BAFNi = 766, respectively. To increase the efficiency of phytoremediation facilities, the authors suggest using marsh calla (Calla Palustris) as an autochthonous species for northern territories. The model experiment results have revealed that this plant species has a high level of tolerance to these metals and possesses the potential for phytoremediation. Calla Palustris most effectively accumulate Fe in absolute terms, and Ni in relative terms. Compared with the reference data, during the 4 weeks of the experiment, the concentration of Fe in plant tissues increased by 1300 mg/kg of dry weight when grown in a solution with a concentration of 5 mg/dm3. The concentration of Ni in plant tissues increased by more than 300 times when grown in a solution with a concentration of 0.5 mg/dm3.
