Soil-Enzymes and Antioxidants Activities of Edible Vegetables Grown in Soils Polluted by Gas Flaring

Associated gas flaring has several consequences on the environment. This study was aimed at assessing impact of soil enzymes and plant antioxidant activities from flare-bearing communities in Nigeria. Soil samples were obtained farmlands Ukwa West Izombe sites, as well unpolluted site Olokoro (used control). The level urease, dehydrogenase, phosphatases, lactate dehydrogenase (LDH) selected plants (Gnetum africanum [GA], Piper guineense [PG], Gongronema latifolium [GL], Pterocarpus mildbraedii [PM]) evaluated using standard methods. results showed that urease significantly higher (P < 0.05) than control soil. Dehydrogenase (DHA) phosphatases recorded for compared with control. For plants, superoxide dismutase (SOD), glutathione S-transferase (GST) peroxidase (GPx) a significant all assayed site. GPx GA PG not > when control, except PM GL which decrease GPX SOD activities, respectively. catalase enzyme also decreased grown Ukwa, while an increase seen overall variability is indication ecosystem are altered by stress load pollutants could serve bio-indicators ecological risks bioremediation.
