Petroleum Products in Soil Mediated Oxidative Stress in Cowpea (<i>Vigna unguiculata</i>) and Maize (<i>Zea mays</i>) Seedlings

Abstract

The effects of petroleum products (kerosene, diesel, engine oil and petrol) treatment of soil at various sublethal concentrations (0.0%, 0.1%, 0.25%, 0.5%, 1.0%, 1.5% and 2.0%) on oxidative stress markers (lipid peroxidation, superoxide dismutase activity, catalase activity and xanthine oxidase) were studied in cowpea and maize seedlings. The results indicated that the petroleum products caused a significant increase in lipid peroxidation and a significant decrease in the activities of the antioxidant enzymes: Superoxide dismutase, catalase and xanthine oxidase activities. Kerosene had a greater effect on these indicators of oxidative stress than did the other petroleum products. The effects on lipid peroxidation and antioxidant enzymes were more pronounced in cowpea seedlings than in maize seedlings.

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

“…While reports on the effects of contaminants on physiological processes of plants have always been an increase in SOD, the present result showed that addition of crude oil to soil caused reduction of various SOD activities (Table 3). This agrees with the information in literature (Achuba, 2014). Achuba (2014) observed an increased SOD in cowpea seedlings at higher doses of petroleum and a decreased level of SOD at lower doses.…”

“…This agrees with the information in literature (Achuba, 2014). Achuba (2014) observed an increased SOD in cowpea seedlings at higher doses of petroleum and a decreased level of SOD at lower doses. According to Sgherri et al (2000), different levels of SOD activity might occur depending on stress intensity, species of plant and growth conditions.…”

“…Plants raised in soils tainted with petroleum have been reported to exhibit retardation in growth parameters (Onwusiri et al, 2017;Osuagwu et al, 2017) and metabolic alterations (Achuba, 2006). Moreover, plants raised in crude oil tainted soil were reported to exhibit increased free radical generation, oxidative stress and lipid peroxidation (Achuba, 2014). Recently, spent engine oil was reported to adversely affect the germination and growth parameters of fruited pumpkin (T. occidentalis), Zea mays, Arachis hypogea and Vigna unguiculata (Onwusiri et al, 2017;Osuagwu et al, 2017) Tropical African palm tree, Elaeis guineensis Jacq., is a highly profitable cash crop and is reputed economically, the most efficient oil crop worldwide (Dislich et al, 2017).…”

Soil Pollution by Petroleum-Derived Substances and its Bioremediation: The Effect on Aphis fabae Scop. Infestation and Antioxidant Response in Vicia faba L.

“…It is worth mentioning, however, that the cited authors conducted their studies 48 days after the instance of soil contamination; and, in the present experiment, this effect still continues after three years. Achuba's [49] investigation indicated that contaminations by petroleum products (kerosene, diesel, engine oil, and petrol) at 2% concentrations caused a decrease by approximately 10% of CAT activity in the leaves of cowpea and maize seedlings, with these studies continuing only up to 12 days after the soil contamination.…”

Effects of soil treatment with abattoir effluent on morphological and biochemical profiles of cowpea seedlings (<i>V.unguiculata</i>) grown in gasoline polluted soil

“…Soil polluted with petroleum hydrocarbons is devoid of water and oxygen as well as shortage of available forms of carbon, nitrogen and phosphorus (Wyszkowska and Kucharski, 2000;Wyszkowski and Ziolkowska, 2008). This reduces the ability of the soil to support living organisms present in it as well as its inability to carry out biochemical activities (Agbogidi and Eshegbeyi, 2006;Makoi and Ndakidemi, 2008;Achuba, 2014;Achuba and Okoh, 2014;Alrumman et al 2015). Petroleum hydrocarbons have been described as a phytochemical substance (Peretiemo-clarke and .…”
