Absorption Capacity of Copper and Lead in the Case of Phragmites Australis Plant Species

Abstract

The main objective of the current research is to determine the absorption capacity of heavy metals (copper and lead) in the case of Phragmites Australis plant species (root, stalk, leaf, flower). The plant samples was taken from the Moldova and Siret Rivers, belonging to the Siret hydrographic basin, respectively upstream of Roman city, Romania-Siret River, downstream Roman city -Moldova River, downstream confluence Moldova/Siret- Siret River and Dragesti-Siret River. A high absorption capacity of copper was recorded, in the case of Phragmites Australis plant species (especially in the root of the plant for all point analysed). A very higher absorption capacity of lead was recorded, in the flower, in the case of Phragmites Australis plant species (1.45�39.56 mg/kg dry matter) for all point analysed.
