The aim of the study is to isolate indigenous bacterial species which have ability degrade crude oil. Samples were collected from an oil polluted site in Ejama-Ebubu Eleme Rivers state. samples taken five spot (A-E), depth 0-15 (A1– E1) and 15-30 (A2– E2) sterile polyethylene bags, using appropriate equipment, then laboratory for analysis, Physicochemical parameters such as pH, nitrate, sulphat...

Subsurface contaminants such as coal tar, creosote, diesel fuel, and other petroleum-derived materials typically exist as very complex chemical mixtures. Risk assessment is useful for site management if a single metric can represent the composition-dependent risk profile of the mixture. This paper examines the factors governing human health risk assessment for multicomponent nonaqueous phase li...

A dynamic multimedia fugacity model was used to evaluate the partitioning and fate of petroleum hydrocarbon fractions and aromatic indicator compounds within the soil: oil matrix of three biopiles. Each biopile was characterised by four compartments: air, water, soil solids and non-aqueous phase liquid (NAPL). Equilibrium partitioning in biopile A and B suggested that most fractions resided in ...

Although mass spectrometry has been studied extensively in the past 50 years for analysis of petroleum and other fossil fuels, comprehensive characterization of total petroleum composition across a wide boiling range remains a challenge. In this work, we report our efforts in combining GC separation, field Ionization, and time-of-flight high-resolution mass spectrometry (GC-FI-TOF HRMS) for det...

In this study the full-scale operation of soil flushing with air sparging to improve the removal efficiency of petroleum at depths of less than 7 m at a military site in Korea was evaluated. The target area was polluted by multiple gasoline and diesel fuel sources. The soil was composed of heterogeneous layers of granules, sand, silt and clay. The operation factors were systemically assessed us...

Introduction: The increasing trend of petroleum production in Iran and lack of proper and systematic management of waste products in the deposition of petroleum storage tanks have made the existing hydrocarbons as a major hazards to the environment. In this study, the ozonation process was used to remove the petroleum deposits. Materials and Methods: In this experimental study, effects of pH, ...

Hydrocarbon wastes generated from remediation activities contain Total Petroleum (TPH), Polyaromatic (PAH) and Heavy Metals whose respective concentrations are yet to be determined. There is limited available literature particularly in Nigeria, on whether the concentration of these after treatment exceeds permissible limits. The present work aims determine petroleum hydrocarbon residual ash tre...

Phytoremediation is an emerging environmental-friendly technology that can be a promising solution to remediate oil-polluted soils. The impact of high amount of hydrocarbons on growth characteristics of burningbushand common flax was evaluated in this survey. The influence of organic fertilizers was also assessed on growth of plant species in oil...

hydrocarbons (PAHs) in coastal marine sediments: case studies in Cotonou (Benin) and Aquitaine (France) areas. Marine Pollution Bulletin 40, 387–396. Steinhauer, M.S., Boehm, P.D., 1992. The composition and distribution of saturated and aromatic hydrocarbons in near shore sediments, river sediments, and coastal peat of Alaskan Beaufort Sea: implications for detecting anthropogenic hydrocarbon i...

Fuel pollution is a significant problem in Antarctica, especially in areas where human activities occur, such as at scientific research stations. Despite this, there is little information on the effects of petroleum hydrocarbons on Antarctic terrestrial biota. The authors demonstrate that the Antarctic mosses Bryum pseudotriquetrum, Schistidium antarctici, and Ceratodon purpureus, and the Antar...
