This exploration evaluated the bioremediation potential of garbage of enzymes (GE) from fermented organic wastes on Fe, Co, Zn, Cu concentrations on crude oil polluted soil. The natural gas polluted soil was self-possessed from Agbura community of Bayelsa State. The crude oil polluted were divided into 6 groups. Group 1and 2 served as control and untreated soil samples respectively. Group 3 was treated with 30% of GE from fermented watermelon and pineapple wastes. Group 4 was treated with 50% of GE from plantain and banana wastes. Group 5 was treated with 70% of GE from plantain, watermelon, pineapple and banana wastes. Group 6 was treated with 100% of GE from plantain, watermelon, pineapple, and banana peels. Group 3, 4, 5, and 6 were treated for 30, 60, 90, 120, 150, and 180 days using 90 days GE from organic peel wastes. The Cu concentration in group 6 (91.05±0.0%) after treatment with 100% of GE were significantly higher than those of group 2 (17.34±0.02%). The Zn concentration in group 6 (83.25±0.03%) after treatment with 100% of GE were higher than those of group 2 (12.05±0.0%). The Co concentration in group 6(81.06±0.04%) after treatment with 100% of GE were higher than those of group 2 (17.33±0.02%). GE from organic peels demonstrated percentage Fe, Cu, Zn, and Co percentage removal from crude oil polluted soil after treatment, hence could be used as bioremediation tool in crude oil spill cleanup.
This evaluation analyzed the proximate and heavy metal compositions of locally processed cassava food product (Abacha) in selected markets in Yenagoa. The Abacha used for this study was purchased from Tombia, Opolo, Swali, and Azikoro markets. Proximate and heavy metal were determined carried based on standard methods. The ash, moisture, rude lipid, crude fiber, and carbohydrate of Abacha obtained from Tombia market for week 3 were 2.01±0.15%, 3.16±0.11%, 3.82±0.03%, 3.51±0.023%, and 86.59±2.11% respectively The ash, moisture, rude lipid, crude fiber, and carbohydrate of Abacha obtained from Swali market were 3.71±0.10%, 3.31±1.03% 3.25±0.20%, 3.84±0.16%, and 85.08±0.59% respectively. The Pb, Cr, Cd, an Hg levels in Abacha purchased from Tombia market for week 3 were 2.10±0.10%, 2.05±0.02%, 2.07±0.02%, and 2.10±0.00% respectively. The Pb, Cr, Cd, an Hg levels in Abacha purchased from Swali market for week 3 were 2.14±0.02%, 2.17±0.21%, 2.11±0.30%, and 2.17±0.02% respectively. The carbohydrate content in Abacha purchased from Opolo market was highest followed by Swale market, Azikoro market while the least was Tombia market. The Pb, Cr, Cd, and Hg observed in Abacha from Tombia and Swali markets were within the reference daily intake values for both women and men. There should be profound control of inorganic mineral concentration of locally processed food in Yenagoa, Bayelsa from time to time in order to thwart the incidence of metal-induce toxicity, resulting from consumption of food loaded with pollutant by the public.
