Crude oil-polluted marine sediment from Bonny River loading jetty Port Harcourt, Nigeria was treated in seven 2.5 l stirred-tank bioreactors designated BNPK, BNK5, BPD, BNO(3), BUNa, BAUT, and BUK over a 56-day period. Five bioreactors were biostimulated with either K(2)HPO(4), NH(4)NO(3), (NH(4))(2)SO(4), NPK, urea or poultry droppings while unamended (BUNa) and heat-killed (BAUT) treatments w...


 The study assessed the removal of total petroleum hydrocarbon (TPH) and polyaromatic hydrocarbons (PAHs) from spent engine oil (SEO) contaminated soil through bioenhancement bacteria isolated SEO polluted soil. Sterilized was subjected to a three level contamination before addition sterilized biostimulants including powdered cow dung (CD), cocoa pod husk (CPH) compost (made fresh CPH CD)...

The term “Total petroleum hydrocarbons” (TPH) is used to describe a complex mixture of petroleum-based hydrocarbons primarily derived from crude oil. Those compounds are considered as persistent organic pollutants in the terrestrial environment. A wide array amendments increasingly for remediation TPH-contaminated soils. Organic not only supply source carbon and nutrients but also add exogenous...

Assessing oil pollution using traditional field-based methods over large areas is difficult and expensive. Remote sensing technologies with good spatial and temporal coverage might provide an alternative for monitoring oil pollution by recording the spectral signals of plants growing in polluted soils. Total petroleum hydrocarbon concentrations of soils and the hyperspectral canopy reflectance ...

Zero-valent iron nano-particle (nZVI) was modified with Spondias mombin (Sm) leaves extract (Sm-nZVI) for the removal of total petroleum hydrocarbons (TPH), hydrocarbon content (THC), and polycyclic aromatic (PAHs) from contaminated soil. Advanced analytical tools such as Fourier Transform Infra-Red (FT-IR) Spectrophotometer, Scanning Electron Microscope(SEM) X-ray diffractometer (XRD) were use...

This study was aimed at assessing the soil conditions of previously remediated oil spill sites in Niger Delta region. Ninety-six (96) samples were collected over two seasons from three states (Rivers, Abia, and Imo). Gas Chromatographic (GC) Analysis used analyzing for Total Petroleum Hydrocarbon (TPH) content while heavy metals analysis Lead (Pb), Zinc (Zn), Copper (Cu), Chromium (Cr) Iron (Fe...

Bacterial community dynamics and biodegradation processes were examined in a highly creosote-contaminated soil undergoing a range of laboratory-based bioremediation treatments. The dynamics of the eubacterial community, the number of heterotrophs and polycyclic aromatic hydrocarbon (PAH) degraders, and the total petroleum hydrocarbon (TPH) and PAH concentrations were monitored during the biorem...
