[Display omitted] •The obtained results from the research suggest that aerial organs of Mulberry nigra have had significant difference for mercury accumulation in various concentrations.•According to the results, Mulberry nigra species, seems to be an appropriate species for refining soils contaminated by mercury.•Mercury pollution is most pollution in soil of north of Iran in industrial park area.•Studies in environment heavy metal pollution in soil of urban forestry in most important for human health.•Mulbery nigra is a fast-growing species from medium to high trees, is resistant towards various soils and prefers visors to shade-friendly sites .In this research it was studied that how much a Mulbery nigra could absorb the mercury from the environment. Phytoremediation is one of the methods for Bioremediation of the soils which has been noticed in recent decades. Two years sapling of Mulberry nigra selected and Mercury(II) nitrate solution with 30, 50 and 70 mg/L concentrations, after add solutions in to soil of sapling Mulberry nigra, eight months’ later leaf, stem and roots were selected and Measuring mercury was determined by Atomic Absorption Spectrometer. The maximum level of mercury accumulation in the leaf, stem and root was 55.67, 50 and 65 mg/kg, respectively. Mercury could be absorbed easily by the plant’s root and accumulated in the plants.
