Current bioremediation techniques for petroleum-contaminated soils are designed to remove contaminants as quickly and efficiently as possible, but not necessarily with postremediation soil biological quality as a primary objective. To test a simple postbioremediation technique, we added earthworms (Eisenia fetida) or wheat (Triticum aestivum) straw to petroleum land-farm soil and measured biolo...

Rhizoremediation potential of different wild plant species for total (aliphatic) petroleum hydrocarbon (TPH)-contaminated soils was investigated. Three-week-old seedlings Acacia inaequilatera, pyrifolia, stellaticeps, Banksia seminuda, Chloris truncata, Hakea prostrata, Hardenbergia violacea, and Triodia wiseana were transplanted in a soil contaminated with diesel engine oil as TPH at pollution...

Nutrient deficiency severely impairs the catabolic activity of indigenous microorganisms in hydrocarbon rich environments (HREs) and limits the rate of intrinsic bioremediation. The present study aimed to characterize the microbial community in refinery waste and evaluate the scope for biostimulation based in situ bioremediation. Samples recovered from the wastewater lagoon of Guwahati refinery...

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...

The present study investigated the coupling effect of biodegradation and media filtration in treating hydrocarbon contaminated water. The study recorded reductions in total petroleum hydrocarbon, total dissolved solids, turbidity and microbial load. The study was essentially a simulated pump and treat process that involved the pumping of hydrocarbon contaminated water for treatment in a locally...

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...

A short-term ecological study was carried out to comparatively evaluate the phytoremediation potential potential of two leguminous plant species. This aimed at quantifying residual TPH as index for assessing a post-phytoremediated crude oil contaminated soil. Plant and soil analysis were carried out using the photometric method of American Petroleum Institute (API). Result has shown that Leucae...

This study adopted an ecosystem services approach to pollution management by investigating the impact of biochar-mediated remediation on soil nitrogen, abundance nitrogen cycling bacteria and activity ammonia monooxygenase (AMO) enzyme in petroleum-polluted using two biochar types applied at treatment levels with monitoring over 15 weeks. The corn cob-derived (CDB), generally, had a stronger re...

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...
