Genotoxic responses towards chronic exposure of Chaetoceros tenuissimus and Skeletonema costatum to water accommodated fraction of petroleum hydrocarbons (WAF-P) were evaluated as biomarkers of petroleum hydrocarbons pollution. The DNA damage caused by water accommodated fraction of petroleum hydrocarbons was assessed in terms of the DNA integrity measured by alkaline unwinding assay. The compa...

Administration (EIA) provides analyses used to assess proposed energy and environmental policies and to make energy forecast for the Annual Energy Outlook (AEO). The tool used by EIA for these mid to long term forecasts is the National Energy Modeling System (NEMS), a large-scale model of energy supply, demand, prices, and technologies. One component of NEMS is the Petroleum Marketing Module (P...

The wastewater from petroleum industries contains high organic matter content, oil and grease, dissolved solids and turbidity. The petroleum wastewater normally treated in a plant comprising of primary, secondary and tertiary treatments. The high organic loading needs to be treated in biological treatment step. Biological treatment can be suspended growth or attached growth type. Activated slud...

Currently, petroleum hydrocarbons are the most abundantly used chemicals in the world. Manufactured from crude oil, petroleum hydrocarbons are found in gasoline, kerosene, fuel oil, asphalt, and even some chemicals used in home or at work. Almost every person on this planet has once or more used a petroleum product or byproduct. Due to their wide de mand, they are transported all over the world...

Microbial bioremediation of petroleum wastewater by phenol-degrading-bacteria holds promise in circumventing the issue of petroleum-spill related pollution. Herein, biodegradation of petroleum wastewater samples collected from oil refinery site was carried out in a fluidized bed bioreactor by Ca-alginate immobilized biomass of phenol-degrading strains of Bacillus cereus (AKG1 MTCC9817 and AKG2 ...

Focused open-vessel microwave-assisted extraction (FOV-MAE), closed-vessel microwave-assisted extraction (CV-MAE), and accelerated solvent extraction (ASE) were used for extraction before determination of organochlorine compounds (polychlorinated biphenyls, DDT, toxaphene, chlordane, hexachlorobenzene, hexachlorocyclohexanes, and dieldrin) in cod liver and fish fillets. Wet samples were extract...

BACKGROUND An experimental work was reported to estimate the increase in distillate yield for a compound parabolic concentrator-concentric tubular solar still (CPC-CTSS). The CPC dramatically increases the heating of the saline water. A novel idea was proposed to study the characteristic features of CPC for desalination to produce a large quantity of distillate yield. A rectangular basin of dim...

An application of solid-phase extraction (SPE) for high-performance liquid chromatography (HPLC) analysis was developed for the rapid determination of benzoic acid and sorbic acid in Thai rice wine and distillate products. The SPE extraction gave promising results with 95.7+1.7% recovery for benzoic acid standard, and 95.2+2.3% for sorbic acid standard. Mean relative standard deviation (RSD) fo...

This study investigates the effect of ageing on the qualitative and quantitative composition of plum distillate in contact with oak wood chips. Maturation was performed with lightly toasted French oak (Quercus sessiflora and Quercus robur) chips or oak chips made from fragments of empty barrels that had been used for ageing cognac. The effects of oak chip dose, process temperature, ageing syste...

The vitamin E analogs δ-tocotrienol (DT3) and γ-tocotrienol (GT3) have significant protective and mitigative capacity against the detrimental effects of ionizing radiation (IR). However, the expense of purification limits their potential use. This study examined the tocotrienol-rich fraction of rice bran (TRFRB) isolated from rice bran deodorizer distillate, a rice oil refinement waste product,...
