This study aimed to determine the impact of artisanal refinery operations on physicochemical and microbiological properties soil water in Igia-Ama, Tombia Kingdom, Rivers State, Nigeria. Physicochemical parameters along with concentrations heavy metals, polyaromatic hydrocarbons (PAHs), total petroleum hydrocarbon (TPH), benzene, toluene, ethylbenzene xylene (BTEX), polychlorinated biphenyls (P...

Production and spillage of petroleum hydrocarbons which is the most versatile energy resource causes disastrous environmental pollution. Elevated oil degrading performance from microorganisms is demanded for successful microbial remediation of those toxic pollutants. The employment of biosurfactant-producing and hydrocarbon-utilizing microbes enhances the effectiveness of bioremediation as bios...

13 Oil wastes produced in large amounts in the processes of oil extraction, refining, and 14 transportation are of great environmental concern because of their mutagenicity, toxicity, high 15 fire hazardousness, and hydrophobicity. About 40% of these wastes contain radionuclides; 16 however, the effects of oil products and radionuclides on soil microorganisms are frequently 17 studied separatel...

Background: Water plays an essential role in supporting life on earth and sea worldwide, requiringclean, safe, high quality and sustainable resources. Nowadays, many water resources have been contaminatedwith toxic compounds originating from petroleumdue to economical and industrial developments. There is anurgent need to clean up the waters with environmentally friendlyand inexpensive methods...

The biodegradability of leachate from the land treatment of hydrocarboncontaminated soil was investigated in the laboratory using respirometry and toxicity test­ ing in combination with total petroleum hydrocarbon (TPH) measurements. Soil in land treatment units (LTU) had been contaminated with a diesellike hydrocarbon mixture formerly used as a diluent for crude oil at an oil field in Californ...

Oil spills have immediate adverse effects on marine ecological functions. Accurate assessment of the damage caused by oil spill is great significance for protection ecosystems. In this study observation data Chaetoceros and shellfish before after Penglai 19-3 in Bohai Sea were analyzed least-squares fitting method radial basis function (RBF) interpolation. Besides, an transport model provided w...

This study presents the proof-of-concept of the "Oil-Spill Snorkel": a novel bioelectrochemical approach to stimulate the oxidative biodegradation of petroleum hydrocarbons in sediments. The "Oil-Spill Snorkel" consists of a single conductive material (the snorkel) positioned suitably to create an electrochemical connection between the anoxic zone (the contaminated sediment) and the oxic zone (...

Salt formations exist in K?z?l?rmak Graben (Central Anatolia, Turkey), which consists of volcano-sedimentary units, and it was stated previous studies that these have a diapiric structure. The adjacent basin, Ayhan Basin, contains bituminous shale operated coal deposits. For this reason, study, is aimed to investigate the oil gas potential by conducting TPH (Total Petroleum Hydrocarbons) analys...

The application of water washing technology for recycling an organic composite solvent consisting of hexane and pentane (4:1; TU-A solvent) was investigated for extracting total petroleum hydrocarbons (TPH) from contaminated soil. The effects of water volume, water temperature, washing time and initial concentration of solvent were evaluated using orthogonal experiments followed by single facto...
