Phytoextraction of arsenic from soil by Leersia oryzoides.
The potential of Leersia oryzoides (rice-cut grass) to remediate arsenic-contaminated soil was studied in greenhouse pot experiments. Leersia oryzoides grown in soil amended with arsenic to a concentration of 110 mg kg(-1), extracted up to 305 mg kg(-1) and 272 mg kg(-1) arsenic into its shoots and roots, respectively, giving a shoot:root quotient of 1.12 and phytoextraction coefficients up to ...
متن کاملPhytoextraction of lead, zinc and cadmium from soil by selected plants
The Pb, Zn and Cd phytoextraction potential of 14 different plants was assessed in a chelate induced phytoextraction experiment. In the used soil heavy metals mainly reside in carbonate, organic matter, and residual soil fractions. The addition of a chelate, 5 mmol/kg ethylenediamine-tetracetic acid (EDTA), increased the proportion of phytoavailable Pb, Zn and Cd in the soil (dissolved in soil ...
متن کاملHeavy Metal Accumulation in Urban Soil: a Phytoextraction Method Review
Lead (Pb), cadmium (Cd), and arsenic (As) are three common non-essential heavy metals found in urban soils and can prove toxic to animals, humans, and some plants at low concentrations. The main exposure pathways of heavy metals in humans are through ingestion and inhalation of soil particles and ingestion of contaminated food. When dealing with contaminated soil in urban environments, activiti...
متن کاملPhytoextraction of Cadmium, Lead and Nickel from a Contaminated Soil by, Hordeum Vulgar L. and Brassica Napus L.
Heavy metals contamination is a major environmental problem which requires immediate human attention. The use of plant species to remove pollutants from soils, generally defined as phytoextraction. In order to evaluate phytoextraction of contaminated soils, a pot experiment conducted using two plants Barley, Canola three kinds of heavy metals (Cd, Pb, Ni) with 3 levels in a completely randomize...
