Phytoaccumulation of zinc by the aquatic plant, Lemna gibba L.

Plant Nutrient Phytoremediation Using Duckweed

“…In recent years, there were many findings reported on the removal of heavy metals by duckweed phytoremediation. Khellaf and Zerdaoui (2009) addressed that the duckweed Lemna gibba L. can be successfully employed to remove Zn from contaminated water by 61 -71%. Another research found that the duckweed L. gibba could remove Zn and Cu rapidly in the first 2 days with concentration reduction higher than 60% and then slowly in the following 8 days with reduction of 10 -20%; however, the removal of Cd was linear and determined by initial Cd concentration and the removal was about 90% after 6 or 8 days with initial concentrations of 0.1 or 0.001 mgL -1 (Megateli et al 2009).…”

Decontamination of Lead from aquatic environment by exploitation of floating macrophyte Azolla microphylla Kauf

“…The physiological processes and phytoaccumulation efficiency are dependent on the specific composition of polluted streams and the climate regime in the country [18] . Many terrestrial and aquatic plants have been screened for their ability to take up heavy metals from contaminated aquatic systems including ground water [19][20] [21][22] [18] . This study emphasizes potency of aquatic plant species, Azolla microphylla Kauf.…”

Phytoprotective influence of bacteria on growth and cadmium accumulation in the aquatic plant Lemna minor

“…Strong attention has been focused on members of the Lemnaceae (duckweed) family, including Spirodela polyrhiza (Rahman et al, 2007), L. minor (Hou et al, 2007;Oporto et al, 2006;Uysal and Taner, 2009), and Lemna gibba (DelCampo Marin and Oron, 2007;Khellaf and Zerdaoui, 2009;Megateli et al, 2009;Mkandawire et al, 2004b), for their abilities to remove metals and metalloids from the environment. L. minor is a small aquatic angiosperm that grows in still waters, having a simple structure with a single root that is not anchored in sediment, and leaves that float on the water surface.…”
