The research finding was explored heavy metal fixation in scallion plants cultivated in rural destinations in Uttaradit Province, Thailand. The heavy metals: Arsenic (As), Zinc (Zn), Lead (Pb), Copper (Cu) and Cadmium (Cd) were extracted from scallion plant parts (consumable stalk and stem). The extraction was done using the digestion method, aqua regia then dry ashing followed by aqua regia, nitric acid and hydrochloric acid. The results showed that the concentrations of Cu, Pb, Zn, Cd and As in the soil samples exceeded the background values in Uttaradit Province. All heavy metals were nearness in an alternate fixation in each piece of the plant. With the exceptions of Zn and Cu, the metal concentrations in the scallion and soil samples surpassed the standards set by the FAO/WHO. The translocations factor examination demonstrated that scallion had the ability to move every substantial metal from the roots to the stalks.
