Comparison phytoextraction of pb, cd, cu and zn by three plant species: cyperusesculentus, daturainnoxia and ricinuscommunis
Background: Population’s exponential growth leads to an increase of human activities that brings large amounts of pollutants that contaminate soils and century plants by metallic elements Trace (ETM). These, like Cu, Pb and Cd cause serious issues. Material and methods: In this study, experiments in culture pots were conducted. Three plant species, Cyperusesculentus, Daturainnoxia and Ricinuscommunis were tested. Cultures were made in two soil types (low polluted and highly polluted soils) contaminated by ETM Cd, Cu, Pb and Zn. They were watered daily with tap water.
