Lead: An introduction to extraction and phytoremediation

Lead is a commonly used metal in modern industry, because of its useful physico-chemical properties, for instance,to application in eletronic equipment. However, the major concern in the use of the current metal refers to theirregular drop, since 40% in the equipment weight corresponds to the lead. The lead, being a heavy metal, fitsbetween the more toxic elements to the environment, and especially to human beings. The lead contamination is aconcern and nowadays researchers are developing Phytoremediation methods for the decontamination of thesepolluted areas. Phytoextraction is the most recommended technique for heavy metals extraction. Thus this paperaims to make a survey of the main uses and the impacts of the lead on living beings, besides studying the applicationof the method of Phytoremediation in contaminated areas by this metal.
