The technology of phytoremediation is cost effective and ecologically friendly in which plant utilizes its natural abilities to restore environment. In nature there are a number of plants existing with innate mechanisms for removing heavy metals from soil, air and water as a survival strategy.  Among several subsets of phytoremediation, the widely studied strategies are (a) phytoextraction (b) ...

Abstract The present study gave a preliminary report on the phytofiltration of iron-contaminated waters and aggravation iron uptake by copper supplementation using Typha latifolia L. in constructed microcosms. During experiment, Fe concentrations reduced up to 1.67 ± 0.076 mg L −1 (94.43% removal efficiency) 0.087 0.013 (97.10% 14th day from initial 30 microcosm setups. Iron accumulation plant ...

Biosorption is a relatively new process that has proven very promising in the removal of contaminants from aqueous effluents. Microorganisms as well as plantand animalderived materials have been used as biosorbents by many researchers. Biomaterial immobilization and chemical modification improves the adsorption capacity and stability of biosorbents. Biosorption experiments over Cu(II), Cd(II), ...

Abstract This paper reviews plants and microorganisms removal of heavy metals from contaminated sites through bioaccumulation. Increased industrial activities have led to the uncontrolled release into environment, resulting in a global increase metal pollution. Heavy are also consumed surface glasses over prolonged period use. pollution is serious problem that can wide-ranging long-lasting impa...

Water pollution due to heavy metals has become a serious environmental concern their hazardous properties. Since conventional water remediation techniques are generally ineffective and non-environmentally friendly, phytoremediation gained increasing attention from worldwide researchers scientists its cost-effectiveness friendliness. Hence, this review first discussed soil remediations. Phytorem...

Some unavoidable drawbacks of traditional technologies have made phytoremediation a promising alternative for removal of arsenic from contaminated soil and water. In the present study, the potential of an aquatic macrophyte Spirodela polyrhiza L. for phytofiltration of arsenic, and the mechanism of the arsenic uptake were investigated. The S. polyrhiza L. were grown in three test concentrations...

The reduced availability of water resources in Egypt has imposed the need to intensify use wastewater for crop irrigation alluvial soils. Relevant effects can derive from contents potentially toxic metals (PTMs) supply soils, crops, and groundwater these areas. For this reason PTM content be monitored evaluate minimize health hazards. Therefore, context, two areas SE Nile Delta subjected 25 yea...

This field-scale hydroponic experiment investigated the effects of plant density and nutrient levels on arsenic (As) removal by the As-hyperaccumulator Pteris vittata L. (Chinese brake fern). All ferns were grown in plastic tanks containing 30 L of As-contaminated groundwater (130 microg x L(-1) As) collected from South Florida. The treatments consisted of four plant densities (zero, one, two, ...
