Given the imminent deterioration of environmental quality, the accumulation of heavy metals in agricultural soil is one of the main concerns worldwide. Therefore, this research aimed to evaluate the adsorption potential of mercury and zinc by Sphagneticola trilobata. After 60 days, the distribution of heavy metals in the roots and the leaves of the plants was determined. As a result, the plant adsorbed mercury between 43.49 and 59.22%, and zinc between 32.68 and 64.37%. According to the bioconcentration and translocation factors of Sphagneticola trilobata obtained in the present work, the phytostabilizing capacity of mercury and zinc is like Eichhornia crassipes and Sorghum bicolor.
