Background and Theoretical Foundations: The aim of this study was to evaluate the heavy metals zinc, copper, cobalt, manganese, selenium, nickel, cadmium and molybdenum in two species of Hammada salicornica L. and Juncus acutus L. in 2018-2019 from Shadegan Wetland.
Methodology: The collection of Hammada salicornica and Juncus acutus in two seasons of summer and winter was in two sites A (Atish region) and site B (Rugbeh region). At each site, there were three sampling stations (first, second, third stations) with a distance of 200 meters. Heavy elements were measured by induction-coupled plasma atomic emission spectroscopy (ICP-OES).
Findings: The results showed that in the Juncus acutus, the highest values of bioaccumulation index of zinc and manganese metals in the leaves of the plant in the first station in summer were 1.60 and 0.85, respectively. The highest values of this index for cobalt and molybdenum in the leaves of the second Juncus acutus in winter were 8 and 37, respectively. Regarding copper and selenium, the highest amount of bioaccumulation index in plant leaves in winter was observed in the third and first stations of 1.11 and 6.22, respectively.
Conclusion: The lowest bioaccumulation index of zinc, copper, cobalt, manganese, selenium and molybdenum was obtained in the roots of the generation plant. In winter, the highest and lowest metal transfer index in the Juncus acutus was related to copper and nickel metals, respectively 22 and 0.02. In summer, the highest and lowest values of molybdenum and nickel were 4.12 and 0.53, respectively. The bioaccumulation index of metals in Juncus acutus and Hammada salicornica showed that these plants have the ability to accumulate heavy metals and are part of accumulator plants, because heavy metals in the leaves and roots of these plants were measured in very small amounts. According to the results of the indicators transition metal Juncus acutus and Hammada salicornica ability to attract and heavy metals have accumulated.
