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)...

Contamination due to improper disposal of oilfield drilling waste is a serious environmental problem all over the world. This study used bench-scale experimental columns to investigate the effectiveness of combining soil vapor extraction (SVE) with bioremediation (bioaugmentation plus biostimulation) in treating drilling waste from onshore oil wells. The drilling waste used in this study was he...

Special Antarctic Blend (SAB) is a diesel fuel dominated by aliphatic hydrocarbons that is commonly used in Antarctic and subantarctic regions. The past and present use of SAB fuel at Australia's scientific research stations has resulted in multiple spills, contaminating soils in these pristine areas. Despite this, no soil quality guidelines or remediation targets have been developed for the re...

contamination of soil was investigated in this study from the tehran oil refining co. of iran. fifteen soil samples were collected at several points in the azimabad, 15 km south of tehran city, iran. samples were collected at depths of 0–30 cm. control sampleswere prepared to determinebackgroundlevels ofsoil contaminationwithpetroleumhydrocarbonsfor comparison with contaminatedsites. total petr...

total petroleum hydrocarbon ( tph ) are environmental contaminants that are released into the marine environment through oil spills, industrial and domestic activities. tph are readily transformed into more hydrophilic metabolites, which are accumulated in bile. thus fish bile can be used as a biomarker of exposure of fish to tph in the marine environment. in this study several stations were se...

Interaksi sinergis antara tanaman-bakteri dapat digunakan untuk meningkatkan kinerja fitoremediasi tanah yang terkontaminasi hidrokarbon (HC). Penelitian bertujuan karakterisasi plant growth promoting rhizobacteria: Azotobacter sp. dan Pseudomonas dalam limbah minyak bumi menggunakan tanaman sorgum (Sorghum bicolor L.). rancangan acak kelompok faktorial (RAK-Faktorial) terdiri dari inokulasi se...

Soil structure is an important key in the bioremediation process; for instance, clay soils tend to have high absorption of pollutants and low rates due their plasticity oxygen restrictions. This work assesses seven different treatments contaminated soil using lime, silica nanoparticles, both components combination. After a three-month treatment, variation granulometry, pH, porosity, cation exch...

A novel bacterial strain was isolated from industrially contaminated waste water. In the presence of crude oil, this shown to reduce rate total petroleum hydrocarbons (TPH) up 97.10% in 24 h. This bacterium subsequently identified by 16S rRNA gene sequence analysis and affiliated Serratia genus RDP classifier. Its genome sequenced annotated, genes coding for catechol 1,2 dioxygenase naphthalene...

Background & Aims of the Study: A feed forward artificial neural network (FFANN) was developed to predict the efficiency of total petroleum hydrocarbon (TPH) removal from a contaminated soil, using soil washing process with Tween 80. The main objective of this study was to assess the performance of developed FFANN model for the estimation of   TPH removal. Mater...
