“…It was also noticed that D. reflexa plant amended with SC grew better and taller (about 25 % more than other treatments) with lots of fibrous roots than other treatments in the experimental set up. The result is similar to that of (Palmroth et al, 2002) , who recorded 60 % loss of diesel fuel in 30 days in diesel contaminated soil planted with pine tree and amended with NPK fertilizer. It has been found that the best reduction in TPH in vegetated treatments occurred when the fertilizer ratio was 100 : 2 : 0.2 (C : N : P) 26) .…”

The phytoremediation potential of Dracaena reflexa to remediate diesel contaminated soil was determined in a greenhouse study. D. reflexa was planted in soil contaminated with different concentrations of diesel fuel (1, 2.5 and 5 wt%). 5 (wt%) of three different organic wastes [tea leaf (TL), soy cake (SC) and potato skin (PS)] were mixed with the soil and monitored for 270 days. The results of the biodegradation of oil and its fractions showed a reduction of 90 % and 98 % of total petroleum hydrocarbons (TPHs) in soil amended with SC, at 2.5 % and 1 % fuel, respectively. It was observed that in the non-cultivated polluted soil the TPHs, were reduced by 24-27 %. Soil amended with SC provided the greatest diesel fuel loss when compared to other organic waste supplements. D. reflexa roots did not accumulate hydrocarbons from the soil, but the number of hydrocarbon utilizing bacteria was high in the rhizosphere, thus suggesting that the mechanism of the oil degradation was via rhizodegradation. This study has shown that D. reflexa amended with organic wastes has a potential for biodegrading hydrocarboncontaminated soil.

“…The accumulation of heavy metals in J. curcas tends to occur mainly in the roots and to a lesser degree in the leaves and stems. Palmroth et al (2002) also agreed that plant roots stimulate the degradation of toxic organic materials. Furthermore, roots act as a medium for soil microorganisms to speed up the organic pollutant biodegradation rates.…”

Problem statement: The chemical pollution of soil has become a major source of concern and has posed serious health problems within the last few years in many developed nations. A variety of organic and inorganic pollutants, including heavy metals, are being mixed in with the cultivated soil and water. Sewage sludge was one of the major sources of enrichment of heavy metals. These pollutants are eventually transported to the natural vegetation and cultivated crops and concentrated in food chains, with possible detrimental effects on human health and wild-life. Thus, soil contaminants need to be cleaned up to improve environmental safety. Approach: Research was conducted to elucidate the potential of Jatropha curcas L. to clean toxic heavy metals derived from sewage sludge. J. curcas seedlings were planted on six different planting media T0 (100% soil-control), T1 (80% soil and 20% sewage sludge), T2 (60% soil and 40% sewage sludge), T3 (40% soil and 60% sewage sludge), T4 (20% soil and 80% sewage sludge) and T5 (100% sewage sludge) for a period of three months. The growth performance, including height and diameter, of J. curcas was measured using diameter tape, while the basal diameter was measured using a venier caliper every two weeks. Plant samples were collected after harvest and soil samples were collected before and after planting. The ICP-MS was used to determine the concentration of heavy metals in the planting medium and plant parts. Results: According to the growth parameters, the composition of 60% sewage sludge mixed with 40% soil was suitable for achieving optimum J. curcas growth. This plant was able to remove heavy metals (Zn, Pb, Cr, Cd and Cu) effectively from the medium containing 100% sewage sludge and after harvesting, the concentrations of Zn, Pb, Cr, Cd and Cu in T5 ( 100% sewage sludge medium) were decreased by 67.7, 78.3, 77.2, 78.5 and 75.0%, respectively from the initial values. The highest levels of Zn (29.5 mg kg ) accumulation were found in the roots, whereas the highest Pb and Cr concentrations were observed in the leaves and stem, respectively. Conclusion/Recommendations: The roots of J. curcas were found to be suitable for the uptake of heavy metals in sewage sludge, especially Zn. Cr was also adsorbed effectively by the leaves. Thus, J. curcas was a suitable plant to use as a phytoremediator to clean heavy metals, in particular Zn, Cu and Cr. However, a study determining, the short term effects of the large scale use of sewage sludge on trees /-field crops/-leafy vegetables and environmental its impact needs to be carried out.

1) Phytoremediation-the use of plants for the in situ treatment of contaminated soil and water-has recently emerged as an inexpensive and user-friendly alternative to traditional methods of environmental clean-up. The present article outlines the characteristics of phytoremediation based on accumulated research evidence, along with discussions on its advantages and disadvantages. It further reviews various mechanisms involved in the phytoremediation processes: phytoextraction, rhizofiltration, phytostabilization, phytovolatilization and phytodegradation. Along the way, the author summarizes examples of its applications to environmental pollution control. These include wastewater treatment, removal of heavy metals, and hydrocarbons, remediation of recalcitrant contaminants, phytoremediation of radionuclides, and application of transgenic plants for enhanced biodegradation and phytoremediation. The remainder of the article briefly concludes with directions for future research.
