“…More copper was also found to be accumulated in the root than shoot by Luhach and Chaudhry, [11] and Ahmadpour et al [8] but to a lesser extent. This same trend was observed in J. gossypifolia and J. multifida, however, the concentration of copper accumulated in the root of J. gossypifolia in this study is lower than that reported by Awokunmi et al [12] for copper translocated to the root of J. gossypifolia in heavy metal contaminated soil from different dumpsites. Also, the accumulation of copper both in the root and shoot progresses as J. curcas had the highest followed by J. multifida, then J. gossypifolia having the least.…”

“…Some of these studies clearly demonstrated the potential of J. curcas to phytoremediate heavy metals contaminated media. For the other species, the effect of EDTA on the phytoextraction of heavy metals by J. gossypifolia from dumpsite was reported by Awokunmi et al [12]. The success of J. curcas is attributed to its highly effective and dedicated mechanism against abiotic pressures making it possible to endure severe climatic condition including excessive dryness, arid and seriously polluted soils [13,14].…”

The comparative metal uptake and phytoremediation capacity of Jatropha curcas, Jatropha gossypifolia, and Jatropha multifida in heavy metal contaminated soil from a dumpsite in Ibadan Nigeria were studied. Plants were transplanted into polythene pots containing 2kg of soil (control and dumpsite), using a 3×2 factorial laid out in complete randomized designed. Cu, Zn, Cr, Cd, Pb and Ni concentration was determined in the soil before planting and after harvesting as well as in the roots and shoots of the plant after 12 weeks using the standard method. The heavy metal levels in the control soil are within the permissible limits of WHO/FAO while only Cr and Ni in the contaminated soils are within the limit. The heavy metals concentration in the root of the plants ranged from 0.27-63.14 mg/kg (Cu), 4.82-54.18 mg/kg (Zn), 0.48-3.47 mg/kg (Cr), 1.75-72.37 mg/kg (Pb) and 0.05-3.23 mg/kg (Ni); in the shoots, the concentration ranged from 0.25-33.36 mg/kg (Cu), 5.40-12.48 mg/kg (Zn), 0.29-1.45 mg/kg (Cr), 0.58-8.26 mg/kg (Pb) and 0.05-3.23 mg/kg (Ni). Cd was not detected in the root and shoot of the three Jatropha species. Analysis of variance shows heavy metal uptake was influenced by the interaction of contamination level and Jatropha species. Bioaccumulation factor and Translocation factor ranged from 0.

People in recent times have engaged in the habit of cultivating on abadoned dunpsites or soil collected from the existing ones because of their fertility. Lycopersicun esculentus is one of the vegetables that is mostly cultivated on such sites and also commonly consumed in Nigeria. Uptake of heavy metals by tomato (Lycopersicum esculentus) grown on soil collected from dumpsites located in Ekiti State, Nigeria was determined with a view to monitoring the pollutional status of the environment. Concentration of heavy metals were found in the range of ) and Zn (7.54-91.10) all in mg/kg. The sequence of accumulation is in order of leaf>stem>root>fruit and Translocation factor (TF) values greater than 1 revealed that heavy metals were translocated into the aerial part of the plant. However, the study serves as pathway for the investigation of these heavy metals which may eventually enter the food chain and subsequent ingestion by man.

“…India has the potential of becoming the world's leading producer of biodiesel, as it can be "harvested," and produced from nonedible oils like Jatropha curcas, Pongamia pinnata, Madhuca indica plants etc (Awwokunmi et al 2012;Bauddh and Singh 2012a, b).…”

Environmental decontamination is an integral part of sustainable development. In recent years there has been growing interest in using plants for decontamination. On the other hand, water, soil and air are increasingly contaminated. Large amounts of toxic waste have been dispersed in thousands of contaminated sites spread all over the globe. These pollutants belong to two main classes: inorganic and organic. The challenge is to develop innovative and costeffective solutions to decontaminate polluted environment. Phytoremediation is emerging as an invaluable tool for environmental cleanup. Various strategies are being applied to reduce the accumulation of toxic metals in plants. Cultivation of edible crops in contaminated soils is a subject of human health concern if the contaminant concentration in the edible parts of crops plant exceed the permissible level. In such cases non-food crop production viz. value chain and value additions appears profitable. In this review: (1) the contamination due to industrial effluents in peri urban region of greater Hyderabad, and (2) the strategies to use contaminated soil and water for raising phytoremediation crops, and generation of value products. Crops and products include medicinal and aromatic plants, ornamental plants, biofuels, tree crops, fiber crops, dyes, and plants for carbon sequestration.
