Bioaccumulation capacities of copper(II) ions in Salvinia natans

Abstract

Capacities of the pleustophytes in the purification of the aquatic environments in Polish climatic zone have been evaluated. Studies of bioaccumulation of copper(II) from culture media contaminated with 5, 10, 15 and 20 mg Cu/dm3 by the plants of Salvinia natans species were performed. The process was carried out for 14 days with the use of artificial plant-breeding species. The balance of the content of copper(II) in dry matter of plants and in the culture media was investigated. Capabilities of Salvinia natans to bioaccumulate copper(II) have been confirmed in all contaminated culture media
