“…Among various water pollutants, heavy metals are of major concern because of their persistent and bio-accumulative nature (Rai et al, 1981;Lokeshwari and Chandrappa 2007;Chang et al, 2009;Yadav et al, 2009). Water is an indispensable part for the sustenance of mankind and the increasing awareness about the environment; especially aquatic ecosystems have attracted the attention of researchers worldwide.…”

“…Pb accumulation was only found in the leaves of the plants, with the highest level observed in T4 (4.63 mg kg ) was found in the roots in T4, followed by T5 (0.32 mg kg −1 ) and the minimum (0.06 mg kg Relationship between heavy metal concentrations in the growth medium and plant parts: The higher concentrations of Zn, Cu, Cr, Pb and Cd in the 100% sewage sludge contributed to increased basal area in the T4 and T5 treatments and the height increase in T3, which consisted of 40% soil and 60% sewage sludge, this proportion may have allowed for optimal plant growth stimulation. Yadav et al (2009) reported that the soil or sewage sludge containing higher amounts of Zn compared to the other metals tended to reduce the increase in plant growth. Similar results were also observed in T5 treated J. curcas where the growth quite slow or poor compared to other J. curcas, in which the growth markedly slowed compared to the J. curcas planted in the lower proportions of sewage sludge.…”

“…Kabata-Pendias and Pendias (2001) determined that Pb, Cd, Cr, Hg, Zn and Cu are the most common heavy metal contaminants. These heavy metals, when ingested by humans, may cause several health problems, such as anemia and skin allergies (Yadav et al, 2009).…”

“…The leaves of J. curcas are about 6-5 cm long and 5-7 cm and are usually crowded at the apex of the twig. Yadav et al (2009), in their studies on the uptake of As, Cr and Zn by J. curcas, concluded that this plant exhibits the ability to recover and reclaim the contaminated soils. Not only does J. curcas act as an important alternative biofuel, this plant can grow in diverse types of soil conditions.…”

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.
