Fitoremediation is a method in which plants are used to eliminate the elements of soil, underground, groundwater and even air pollutants.  In this study, the Allium pepper L. (sugar), Chenopodium quinoa Willd. (Kinoa) and Brassica napus L (canola) species have been studied to purify the Pb element from the purification dust with the method of fitoremediation. Complex constructive shelates have also been added to increase the fitoremediation capacity, and changes in the element removal performance of plants have been observed. EDTA, humic acid, 1-10 phenantrolin, nitro and adicin were used as shelate support in heavy metal removal. When the tolerance index (TI) values were studied, the shelate supplement was found to cause changes in the growth of plants and the amount of dry weight. The study studied the quantities of heavy metals in the roots, bodies and leaves of plants and found that there was more accumulation in the roots of species. In particular, the amount of heavy metal accumulation was found higher in the test shells where humic acid, EDTA and nitro shelate were used. When the transfer factor (TF) values are studied in EDTA, humic acid, pyridine and 1-10 feontraline shell A. cepa>C. Quinoa> B. napus, but in the nitro shell C. quinoa> A. cepa> B. Napus was found. The most effective accumulation occurred in A.cepa and C. quinoa. B. napus nitro, known as a hyperacumulator, has been determined that when shelates of piridin and 1-10 phenantrolin are added, they do not show this characteristic. It has been found that species accumulate the Pb element in the roots and transport to the upper organs increased by shelate added. According to this, it shows that humic acid, EDTA and nitro can be used to increase heavy metal intake.

Phytoremediation is a method that plants are used to eliminate the pollutants in soil, underground, surface water and even in weather. In this study, the removal of Pb element from treatment sludge by phytoremediation method using Allium cepa, Chenopodium quinoa and Brassica napus species was investigated. In addition, complex builder chelate was added to increase the phytoremediation capacity, and changes in the element removal performance of the plants were observed. EDTA, humic acid, 1-10 phenanthroline, nitro, pridin were used as chelate support in heavy metal removal.  When Tolerance Index (TI) values were examined, it was determined that the addition of chelate caused a change in the growth of plants and dry weight. In the study, the amount of heavy metal deposition in the root, stem and leaves of the plants was investigated and it was determined that accumulation in the roots of the species was higher. According to the results obtained in the study, It was determined that the accumulation in the roots of the species is more.Especially in the test pots using humic acid, EDTA and Nitro chelate, the accumulation was higher. When TF values were examined,  A. cepa>C. quinoa>B. napus in EDTA, the Humic acid, the pyridine and the 1-10 Phenanthroline chelate and C. quinoa>A. cepa>B. napus in nitro chelation were found. The most effective accumulation occurred  in A.cepa and C. quinoa species.It was determined that B. napus, known as the hyperaccumulator, did not show its property when nitro, pyridine and 1-10 phenanthroline chelates were added.It was determined that accumulation of Pb in the roots and transportation of the element to the upper organs by the Species increases with chelate addition. Accordingly, it is revealed that humic acid, EDTA and nitro can be used to increase heavy metal intake.As a result, in order to use the augmentation mud in agriculture, it needs to be purified from the substances that can damage the living things. Chelate assisted phytoremediation method can be used to remove heavy metal contamination and increase heavy metal uptake from the soil.
