“…Some techniques for removing recalcitrant contaminants include bio-stimulation, bio-augmentation, bioventing, sparging, slurping, phytoremediation, composting, land farming and piles (Vidali 2001). The utilization of brewery mash and earthworm for remediation of petroleum hydrocarbons was adopted by (Okpashi et al 2015). The ability of microorganisms to use-up petroleum hydrocarbon depends on certain factors, such as time or duration, concentration, composition, abiotic and biotic constituents of the contaminated soil (Lee et al 2007).…”

The populace are concern about how their environment is impacted by spend or used engine oil. The spills from spend engine oil posed serious problems to the land and aquatic habitats. Efficient methods but low-cost technique for remediating spends engine oil contaminated soil and restorations of soil fertility are being explored. In response to used engine oil pollution to the soil, the present investigation examined the comparative biodegradation level of spend engine oil contaminated soil using fermented chicken droppings. The soil sample was collected from the uncontaminated site 10 cm below ground level. The sandy/loam soil was sieved with 2.5 mm mesh. A 4 kg of the soil was weighed into each bucket and contaminated with spend engine oil, the soil was contaminated with 150 ml of the spend engine oil at a ratio of 1:27. A 27 kg of chicken droppings was mixed with 27 liters of water in a ratio of 1 kg: 1L. The mixture was left for 7days to ferment and increase the microbial load. The contaminated soil was irrigated using an experimental design that included uncontaminated soil that was irrigated using normal water (positive control), contaminated soil that was irrigated using normal water (negative control) and contaminated soil irrigated using fermented chicken droppings (test). Five hundred mL of the chicken droppings mixture was used to irrigate the soil for 21 days at an interval of 3 days per irrigation. Thereafter, the irrigated soil was screened with gas chromatography linked with mass spectroscopy. There was an observed change in contaminant concentration without fermented chicken droppings. The percentage of differences in the concentrations was recorded in × 10–5% with the presence of Naphthalene and Acenaphthylene with the percent difference of 2.0 × 10–5% and 5.0 × 10– 5%. Result revealed an appreciable decrease in PAHs level compared to the positive and negative control. The findings suggest the positive effect and rapid uptake of the contaminant in the application of fermented chicken droppings. J. Bio-Sci. 29(1): 01-09, 2021 (June)

This investigation was carried out in four different locations mapped out along the river bank. Twelve water samples were collected and six different fresh fish species that are frequently consumed were caught. They include: African red snapper (Lutjanus agennes), Yellow tail (Seriola lalandi), Barracuda (Sphyraena barracuda), Atlantic Croker (Micropogonias undulates), Catfish (Clarias gariepinus) and Tilapia (Oreochromis niloticus). Samples were subjected to screening using gas chromatography and flame ionization detector instrument. Results revealed presence of total petroleum hydrocarbon (TPH) contaminant in all the fish samples and varies with species significantly at p >0.05.The bioaccumulation factor varies in fish species, where the Yellow tail have higher bioaccumulation factor 969,369061, followed by Barracuda 695,067209, Tilapia 667,101072, Catfish 466,368366, African red Sniper 439,616275 and Crocker fish 104,2956024 respectively. This investigation reveal considerably the extent of bioaccumulation of TPH contaminants in aquatic animal models and making unsafe for consumption as some fishes bio-accumulate nonane beyond permissible limit.
