Background: The pattern of heavy metal accumulation in stubborn weed (Sida acuta) was studied for a period of 90 days in a pot experiment.Methods:15 kg of soil in punctured pots was mimicked with two liters of utilized greasing up oil to accomplish 13.3% (w/w) contamination level while pots serving as control contained 15 kg of soil without utilized greasing up oil. The substantial metal focus was lower in the dirt soil with headstrong weed (STW) than the oil - free (OFS) and soil contaminated with utilized greasing up oil without resolved weed (OPS). Results: There were no critical contrasts (p>0.05) in the centralizations of Iron, zinc, nickel and copper in the pot test. In the tissues of stiff-necked weed, convergence of metals demonstrated higher measures of copper in the roots and shoots took after by iron and lead. This study demonstrated that in unshakable weed, iron aggregated in the shoots while copper gathered in the bases of the determined weed. Conclusion: The examples of metal fixation in the leaves of the plants developed in utilized greasing up oil dirtied soil vary from leaves of plants developed being used greasing up without oil soil.
