“…The urea addition might have provided nutrients for the biodegradation of hydrocarbon. This is in agreement with the report of Anukwa et al 21 that the addition of fertilizer enhanced the degradation of TPH. This assertion is justifiable since the rate of degradation was directly proportional to the amount of urea (amendment) added (that is the higher the amount of fertilizer applied, the higher the rate of reduction of petroleum hydrocarbon).…”

Background and Objective: Environmental pollution resulting from oil spills during exploration and exploitation of petroleum resources in the Niger Delta Region is a major challenge in the development of the region. An investigation on the remediation potential of Andropogon tectorum in crude oil polluted soil amended with urea was conducted on a crude oil impacted farmland at Botem Tai. Materials and Methods: A Latin Square Design (LSD) was used for the experiment and the treatments were: P1(Phytoremediation soil without amendment), P2 (Phytoremediation soil with 20 g Urea amendment), P3 (Phytoremediation soil with 40 g Urea amendment) and P (Polluted soil without phytoremediation and amendment) which served as the control. Results: The result showed that Andropogon tectorum was tolerant to and had the potential for phytoremediation of crude oil polluted soil. The addition of urea significantly improved the potential of Andropogon tectorum as higher reductions in TPH (56.93 and 92.66%) and THC (76.52 and 95.81%) were obtained in phytoremediation soil amended with 40 and 20 g urea at 2 and 4 months, respectively as compared to TPH (1.34 and 14.76%) and THC (24.75 and 32.90%) recorded in the control (P). Results also showed that urea amendment increased the uptake and accumulation of hydrocarbon in Andropogon tectorum with the highest accumulation of TPH (1.79±0.01 and 2.68±0.02 mg kgG 1 ) and THC (4.45±0.56 and 26.97±4.11 mg kgG 1 ) in treatment with 40 g urea amendment. Conclusion: Andropogon tectorum amended with 20 g urea increased hydrocarbon reduction rate in crude oil polluted soil; showing its great potential in remediating crude oil polluted soil.

Wastewater is widely used for irrigation and can accumulate heavy metals in the soil, potentially causing harm to human health and the environment. In this study, a pot experiment was used to assess the impact of biochar in soil properties enhancement as well as mitigation of the concentration of Cd, Cu, Zn and Pb to lettuce (Lactuca Sativa) in a soil irrigated with wastewater. Citrus peel biochar pyrolised at 400°C was applied on soil in three levels (0%, 5%, and 10%). The lettuce plant was harvested after 28 days of planting, and the concentrations of heavy metals were determined in roots and leaves using atomic absorption spectroscopy (AAS). The result obtained shows the increase in soil properties with an increase in biochar concentration, the result also shows the p-value of leaves and roots as 0.744 which is not statistically significant at 95% confidence interval. The result obtained shows a decrease in the uptake of heavy metals by the lettuce plant in both parts of the plants (leaves and roots) as follows: the concentration of cadmium was not detected at all levels in both roots and leaves, in un-amended samples (Leaves) the concentration of Cu, Pb, and Zn were 0.141, 0.252, and 1.116 respectively while in roots the concentration of Cu, Pb, and Zn were 0.205, 0.266, and 1.248 respectively. At 5% amendment (leaves) Cu decreased by 48.2% (0.073), Pb by 42.86% (0.144), and Zn by 66.13% (0.378). At 10% amendment (leaves) Cu decreased by 71.63% (0.040), Pb by 53.57% (0.117), and Zn by 48.03% (0.580). While in roots almost similar reductions were observed. These findings show the potential of biochar as an effective strategy for soil properties improvement as well as reducing heavy metals uptake by the plants, with implications for sustainable agriculture in an environment contaminated with heavy metals.
