Plants play an important role in changing ecological conditions due to the use of water, soil and air, and can be used to clean contaminated ecosystems by pollutants such as heavy metals. In this study, the accumulation of heavy metals (cd and Pb) was carried out on two plantains and berries in three stations of Tehran in different levels of contamination. The results of this study showed that the most cadmium adsorption at Keshavarz Boulevard Station by plant species and also in each of the studied regions of the planktonic species showed greater ability to absorb this cd.
While the average lead absorption in all three stations was lower than the annual American standard, the difference in lead concentration was not significant at different stations. But, according to the results of this study, berries had more heavy metal adsorption than the plantain. This study showed a lack of correlation between plant emissions and heavy metal adsorption, but it is believed that selected plant species have the ability to accumulate and accumulate the studied metals in their airspace.
