Effect of abattoir waste water on metabolic and antioxidant profiles of cowpea seedlings grown in crude oil contaminated soil

Abstract

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.

Effect of oil palm leaf treatment of crude oil impinged soil on biochemical indices of cowpea (vigna unguiculata) seedlings

“…This agrees with the present investigation that reported elevated lipid peroxidation and decreased glutathione and vitamin C and uric acid, though these indices were reversed by OPL addition to crude oil tainted soil ( Table 2). Attenuation of crude oil toxicity in cowpea seedlings by organic substances is in literature (Achuba and Erhijivwo, 2017;Achuba and Iserhienrhien, 2018).…”

Role of bitter leaf (Vernonia amygdalina) extract in prevention of renal toxicity induced by crude petroleum contaminated diets in rats

“…Tissue lipid peroxidation has been identified as one significant marker of oxidative stress status of any organism that has been associated with the deleterious effects of petroleum contamination in plants and animals [36], [37]. The process of lipid peroxidation, often times preceded by disruption of the natural antioxidant defence, which in several cases are signalled by the depletion of both enzymatic and non-enzymatic antioxidants [38].…”

Effect of Crude Oil on Growth, Oxidative Stress and Response of Antioxidative System of Two Rye (Secale cereale L.) Varieties

“…The low rate of decomposition of oil and oil products in the environment triggers their accumulation and a gradual increase in their concentration in the environmental objects, including the soil. After getting into the soil, crude oil products destroy its structure, upset the air–water balance [ 1 ], alter the soil physicochemical properties [ 6 , 7 ], inhibit the microbial proliferation [ 1 ], disrupt the soil enzymatic activity [ 8 , 9 ], and have a negative impact on terrestrial and soil mesofauna [ 6 ], as well as on plant growth and development [ 1 , 2 , 3 , 4 , 5 ].…”

“…Secondly, insufficient aeration caused by air displacement from the pore spaces between the soil particles by crude oil leads to root stress and low water availability to the plant [ 11 ]. Moreover, oil pollution minimizes the percentage of organic matter available to plants and reduces the amount of mineral nutrients such as sodium, phosphates, potassium, sulfates, and nitrates [ 8 , 9 ].…”

“…Detailed information about the effect of oil contamination on photosynthetic activity is scarce. For example, it has recently been reported that crude oil pollution reduces overall photosynthetic activity and chlorophyll contents in plants [ 9 , 11 ]. Notable symptoms observed in plants growing on oil-polluted soil also include a decrease in the activity of starch metabolizing enzymes [ 9 ] and a decrease in content of total carbohydrates, total proteins, and total amino acids [ 9 , 12 ].…”
