“…Soil pH directly influences the phytoavailability of metals as soil acidity determines the metal solubility and its ability to move in the soil solution [54]. Metal cations are the most mobile under acidic conditions while anions…”

“…Plant root can influence heavy metal phytoavailability [54] by modifying the soil properties in the rhizosphere [68]. The plant enzymes exuded from the roots should play a key role in the transformation and chemical speciation of heavy metals in soils, which facilitate their uptake by plant [71]- [73].…”

“…These mechanisms include differences in: 1) root architecture; 2) water use efficiency; 3) rhizosphere chemistry; 4) expression and affinity of root surface transporter proteins for metals ; 5) xylem loading of metals and translocation within the plant [82]. Also, the age and the growth stage of the plant can affect concentration of metals in plants [54] [80].…”

“…Phytoremediation can be defined as the process, which uses green plants for the relief, transfer, stabilization or degradation of pollutants from soil, sediments, surface waters, and groundwater [54] [83] [84]. Some plant roots can absorb and immobilize metal pollutants, while other plant species have the ability of metabolizing or accumulating organic and nutrient contaminants.…”

Phytoremediation is a green emerging technology used to remove pollutants from environment components. Mechanisms used to remediate soils contaminated by heavy metal are: phytoextraction, phytostabilisation, phytovolatilization and rhizofiltration. The two first mechanisms are the most reliable. Many factors influence the choice of the suitable phytoremediation strategy for soil decontamination. It depends on soil properties, heavy metal levels and characteristics, plant species and climatic conditions. The present review discusses factors affecting heavy metals uptake by plant species, the different phytoremediation strategies of heavy metal contaminated soils and the advantages and disadvantages of phytoremediation and each of its mechanisms.

“…Many concluded that concentrations of metals in plants growing in the same soil vary between species and even between genotypes of a species 11,12 . Some of the mechanisms, which may be responsible for plant species differences in metal concentrations, have been identified 13 , Also, the age and the growth stage of the plant can affect the concentration of metals in plants 14,15 . Municipal wastewater usage is a common practice where it flows across the agricultural fields.…”

Urban cities throughout the word are growing with the population, and producing the unlimited wastewater to environment. Living standards of urban population and industries are contributing in producing more quality of UWW. In the mean time these UWW are not treated properly because of inadequeate technology applied in the treatment of UWW. It is a common practices thouout the world that utilizing UWW are usually contains Heavy metal. In the present study phytoremidiation studies were carryout in the soils which are amended with UWW. The crops which are grown regularly by using UWW in the area. In this study some of the crops were selected for the study Spinach oleracea L, Zea mays L, Trigonella foenum graecum L these crops are usually consumed by locals citizens for their ingredients in the food preparation., P.purpureum Schumach were used for cattle feed. In the UWW heavy metals are largely presentand they can be remediate by using selected crop species which are artificially irrigated UWW. Phytoremidiation studies by using the selected and locally available crop species used for the study, and it was shows good accumulation ability with low-maintenance. Bio-Concentration Factor (BCF) and Translocation factor (TF) are evident that, crop species performance, apart from practically irrigated crops P.purpureum Schumach is hoard a highest Heavy metals accumulated crop among selected local plants which were grown in the heavy metal contaminated wastewater agricultural fields.
