Determining small amounts of scarce metals in the medicinal plants and its growing place soil by XRF technique
Journal Title: International Journal of Farming and Allied Sciences - Year 2016, Vol 5, Issue 4
Abstract
Scarce metals in a certain quantity can be detrimental for human health, because some of these metals, despite of their very small amounts, are consumed by plants and animals and make the contamination more complex. Three medicinal plants and the soil of their habitat were analyzed with dry and XRF technique. The amounts of these metals in different samples are as follow: for the leaf plant sample A.quenttensis: Y(29.90 mg/Kg), Nb(21mg/Kg), Sm(3.2mg/Kg), for the soil of growing place :y(34.80MG/Kg), Nb(16.80mg/Kg), Sm(6.1mg/Kg), for leaf plant sample of Pulicaria. Y(19.10mg/kg), Nb(16.10mg/kg), Sm(5.80mg/kg) , for the soil of growing place: Y(20.80mg/kg), Nb(20.70mg/kg), Sm(5.50mg/kg), for the leaf plant sample of A.triphylla:Y(18mg/kg), Nb(17.20mg/kg), Sm(3.2mg/kg) for the soil of growing place:Y(18.40mg/kg), Nb(20.50mg/kg), Sm(5.50mg/kg). The amounts of these metals in some plants are more than those of their soil of habitat, however the amounts of some others are fewer than those of their soil, this fact implies the ability of plant in absorbing the metal.
