Heavy metal accumulation in scallion (allium cepa var. aggregatum) fields in uttaradit province, thailand
Chattanong, P. and Jutamas, M.
Abstract Download PDFThe 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.
