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. Keywords: copper, lead, absorption capacity, Phragmites Australis

Highlights

  • The main objective of the current research is to determine the absorption capacity of heavy metals in the case of Phragmites Australis plant species

  • This paper describes the absorption capacity of heavy metals in the case of Phragmites Australis plant species

  • The highest absorption capacity of lead from the soil, in downstream Moldova River- Roman city, was detected in the root of Phragmites Australis plant species, whereas the lowest absorption capacity levels of lead were observed in its leaf and flower
