“…This could be as a result of reduce in photosynthesis of plant leaves due to coating of roots with spent oil which could have disrupted the architecture, and led to decrease in nutrients uptake by the plants (Khan et al 2013;Pezeshki et al, 2000) and other physiological and biochemical activities. This finding conforms to the earlier study of Idowu and Fayinminnu (2015) on Jatropha curca with significant reduction of growth parameters from SLO polluted soil.…”

“…The study site and all the methods carried out in this study followed the same procedures as earlier reported according to Idowu and Fayinminnu (2015; Top soil samples (0-15 cm) were collected randomly with a Dutch auger and trowel from the Forest Floor of Acacia Plantation of the Forestry Research Station. The soil was thoroughly mixed and passed through a 2mm sieve to remove the non-soil particulate.…”

Oil pollution especially Spent Lubricating Oil is a wide environmental problem in Nigeria. It constitutes potential toxic effects on soil, flora, fauna and humans and also making the environment unsightly. This study assessed the potential of kenaf plant as a phytoremediator grown in spent oil polluted soil for a period of 84 days (12 weeks). Pot experiment was conducted in the Nursery site of the Moist Forest Research Station, Forestry Research Institute of Nigeria (FRIN), Ibadan, Oyo State, Nigeria. The treatments: amended (with organic manure) and unamended (without organic manure) soils and three pollution levels (0, 3 and 6%) of spent engine oil, each filled in eight-liter plastic pots with 6 kg soil. Growth parameters: plant height, stem diameter and number of leaves were collected and Total Petroleum Hydrocarbon (TPH) in soil was determined. Data were analyzed using descriptive statistics and ANOVA. Results at 12 weeks (84 days) showed amended (control 0%) treatment having highest plant height (112.17 cm), stem diameter (8.92 cm) and number of leaves (178.43), while 6% unamended level of pollution had the lowest plant height (26.78 cm), stem height (1.62 cm) and number of leaves (8.06). Amended soil had the highest total percentage reduction of TPH (75.90, 90.05 and 90.30%), when compared with unamended soil with lowest values (76.88, 85.18 and 82.36%) at 0, 3 and 6 pollution levels, respectively. Reduction of TPH in the phytoremediation process was in this order of pollution levels 6%> 3%> 0%. This study revealed effectiveness of kenaf with organic amendment in remediating Total Petroleum Hydrocarbon in oil polluted soil, hence a good potential phytoremediator.

“…curcas has been known to be a good phytoremediating plant capable of surviving in adverse heavy metal contamination, for instance, Idowu and Fayinminnu [5] investigated the phytotoxicity of spent oil contaminated soil on J. curcas, while several studies have also demonstrated its ability to withstand metal toxicities. Liang et al, [6] showed that J. curcas exhibited inherent tolerance to cadmium and lead stress and thus a good candidate for phytoremediation; the growth response of J. curcas to heavy metal contaminated sludge has been reported by several authors [7], [8], [9], [10] with various phytotoxic effects observed dependent on the level of heavy metals present in the growth media.…”

“…The research therefore aims at evaluating the comparative phytotoxcity effect of heavy metal contamination on J. curcas, J. gossypifolia and J. multifida with a view to find a common behavioural pattern in the Jatropha spps and consequently, an alternative Jatropha specie with phytoremediating potential. (5) days, sieved using 2mm mesh size and analysed for heavy metals specifically, lead, chromium, Nickel, Zinc and cadmium. This is to ascertain the level of contamination by the metals and thus the effect on the growth factors of the plants.…”

A B S T R A C TThis study investigated the comparative phytotoxcity effect of heavy metal contamination on Jatropha curcas, Jatropha gossypifolia and Jatropha multifida in contaminated soil from a dump site in Ibadan Nigeria. Seeds of J. curcas, J. gossypifolia and J. multifida were planted in a germination tray and later transplanted into polythene pots filled with 2kg of either control soil or heavy metal contaminated soil, a 3 × 2 factorial experiment laid out in complete randomized design (CRD) replicated four times was adopted; treatments imposed include T1 -J. curcas/Control Soil, T2 -J. gossypifolia/Control Soil, T3 -J. multifida/Control Soil, T4 -J. curcas/Contaminated soil, T5 -J. gossypifolia/Contaminated Soil, and T6 -J. multifida/Contaminated Soil. Weekly variation in growth parameters: the plant height, leave production and stem diameter were measured over the course of 12 weeks. The growth parameters were dependent on a combination of both specie type and level of heavy metal contamination of soil. J. multifida (T3) (36.93cm) performed best, comparable with J. gossypifolia (T2) (34.1cm) after 12 weeks while J. multifida (T6) had the lowest mean plant height (7.23cm) which is not significantly (p<0.05) different from other species on the contaminated soil; for leave production, J. gossypifolia (T2) produced the highest mean number of leaves (9.67) which is comparable with J. multifida (T3) (9.00) and less so with J. curcas (T1) (6.67) with significant leave losses on the contaminated soils after 12 weeks; variation in stem diameter shows that J. curcas (T1) had the highest stem girth (1.96 mm) which is comparable to the value obtained for J. curcas (T4) (1.95mm), while J. multifida (T6) had the lowest stem girth (1.09 mm). J. gossypifolia (T2) and J. multifida (T3) had comparable stem girth of 1.57mm and 1.47mm respectively. Toxicity of heavy metals in the contaminated soil greatly affect the growth parameters of the Jatropha.
