Determining small amounts of scarce metals in the medicinal plants and itsgrowing place soil by XRF technique

Scarce metals in a certain quantity can be detrimental for human health, because some of thesemetals, despite of their very small amounts, are consumed by plants and animals and make thecontamination more complex. Three medicinal plants and the soil of their habitat were analyzed withdry and XRF technique. The amounts of these metals in different samples are as follow: for the leafplant sample A.quenttensis:Y(29.90mg/Kg),Nb(21mg/Kg),Sm(3.2mg/Kg) , for the soil of growingplace :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 ofA.triphylla:Y(18mg/kg),Nb(17.20mg/kg),Sm(3.2mg/kg) for the soil of growingplace:Y(18.40mg/kg),Nb(20.50mg/kg),Sm(5.50mg/kg).The amounts of these metals in some plantsare more than those of their soil of habitat, however the amounts of some others are fewer than thoseof their soil, this fact implies the ability of plant in absorbing the metal
