“…Bioremediation is one of the best methods used to restore contaminated soil (Romantschuk et al 2000). Crude oil 1 3 contaminated soils are modifiable by bioremediation since microorganisms are competent in degrading petroleum hydrocarbons (Sangeetha and Thangadurai 2014).…”

Purpose The pollution of agricultural land by crude oil is a wide spread phenomenon in petroleum producing countries of the world. Therefore, there is the need to find effective and eco-friendly means of mitigating the toxic effect of crude oil on crop plants. Methods Green house experiment was conducted with cowpea seeds planted in polybags containing crude oil contaminated soil and similar concentrations treated with known amount of abattoir wastewater. The effect of abattoir wastewater (AWW) treatment of the crude oil contaminated soil on the metabolic and antioxidant properties of the leaves of cowpea seedlings was investigated. The concentrations of total sugar, total protein, total amino acid and β-carotene, chlorophyll, starch metabolizing enzymes as well as oxidative stress markers, lipid peroxidation, catalase, xanthine oxidase, aldehyde oxidase and superoxide dismutase were determined using standard methods. Results Treatment of the crude oil contaminated soil with AWW resulted in decreases in total sugar, total protein and total amino acid as well as increase in the activities of both α-amylase and starch phosphorylase and total chlorophyll and β-carotene levels compared with those in crude oil alone treated groups. Treatment of the crude oil contaminated soil with AWW also significantly decreased lipid peroxidation and Cu/ZnSOD, but increased MnSOD, catalase, xanthine oxidase and aldehyde oxidase activities. Conclusion These observations suggest that abattoir wastewater has the ability to remediate the adverse effects of crude oil polluted soil on cowpea seedlings. Therefore, abattoir wastewater should be harnessed and used in treating crude oil polluted farmland so as to reduce its toxicity on crop plants.

“…Though this approach remains a subject of controversy, several bioremediation processes have been carried out worldwide following accidental oil discharges. Romantschuk et al (2000) showed the effectiveness and the reproducibility of the in situ bioremediation of a ground contaminated by crude oil. Margesin & Schinner (2001) confirmed the effectiveness of the bioremediation on site.…”

“…natural attenuation does not remove the oil with sufficient velocity (Romantschuk et al 2000), even if the natural microbial community has the capacity to perform the degradation (Kauppi et al 2011). Diesel fuel is biologically readily degraded when bottlenecks for microbial activity-low temperature, lack of nutrients, etc.-are removed (Kauppi et al 2011).…”

Purpose Soil restoration is still mainly carried out ex situ by excavating and replacing the contaminated soil. In situ remediation would reduce the costs of soil transportation and this way, the problem is not merely transferred elsewhere. The present study introduces a field case where the aged, oilcontaminated soil in a former fuel station in Finland was treated in situ sequentially with different methods. Materials and methods Several approaches, including soil vapor extraction and biostimulation with electrokinetic pumping, were performed in the field. After these treatments, the dense original portion of the soil beneath the gasoline pump location, ca 100 m 3 , was still contaminated with petroleum-derived volatile organic compounds (VOCs), with concentrations of nearly 10,000 mg kg −1 measured at some hotspots. After a period of electroosmotic water circulation, the electrical field (0.5 V cm −1 , DC) was kept connected for 6 months without addition of water, leading to dewatering and warming of the soil. Results and discussion In contrast to the situation with the original wet soil, VOCs, in lab conditions, were found to volatilize very efficiently from the dewatered soil. When the soil vapor extraction treatment was renewed using perforated tubing installed horizontally at ca 1 m depth in the dewatered soil at the contaminated site, the treatment was efficient and the soil was decontaminated in 5 months. The final VOC concentrations were on average 190 mg kg −1 (n = 13) with the highest value of 700 mg kg −1 at one hotspot. After a risk evaluation, the site was concluded to be sufficiently clean for industrial use. Conclusions Since with many former fuel stations, the contamination consists of both volatile fractions that are difficult to degrade by biological means and heavier compounds for which biostimulation is often suitable, a combination of different methods may be worth pursuing.
