Dissipation of petroleum contaminants in the rhizosphere is likely the result of enhanced microbial degradation. Plant roots may encourage rhizosphere microbial activity through exudation of nutrients and by providing channels for increased water flow and gas diffusion. Phytoremediation of crude oil in soil was examined in this study using carefully selected plant species monitored over specifi...

The objective of this review was to synthesize existing information regarding the effects of petroleum hydrocarbons on marsh macrophytes in a manner that will help guide research and improve spill-response efficiency. Petroleum hydrocarbons affect plants chemically and physically. Although plants sometime survive fouling by producing new leaves, even relatively non-toxic oils can stress or kill...

The two methods of processing synthetic crude from organic marlstone in demonstration or small-scale commercial status in the U.S. are in situ extraction and surface retorting. The considerable uncertainty surrounding the technological characterization, resource characterization, and choice of the system boundary for oil shale operations indicate that oil shale is only a minor net energy produc...

The transportation of petroleum represents one of the most strategically important circulations of resources in the global economy. Its role cannot be overstated. Yet, petroleum has become a “strategically invisible” commodity as its flow has been continuous with limited, but eye-opening, disruptions such as the First Energy Crisis is 1973. Petroleum supplies are virtually taken for granted. Si...

BACKGROUND One of the most important environmental problems is the decontamination of petroleum hydrocarbons polluted soil, particularly in the oil-rich country. Bioremediation is the most effective way to remove these pollutants in the soil. Spent mushroom compost has great ability to decompose lignin-like pollution. The purpose of this study was the bioremediation of soil contaminated with cr...

Large mass casualty gas explosions and catastrophic oil spills are widely reported and receive considerable regulatory attention. Smaller, less catastrophic petroleum product releases are less likely to receive publicity, although study of these incidents might help focus and prioritize prevention efforts. To describe the causes and health impacts of petroleum product release incidents (includi...

Pseudomonas aeruginosa strain SJTD-1 can utilize long-chain alkanes, diesel oil, and crude oil as sole carbon sources. We report the draft genome sequence of strain SJTD-1 (6,074,058 bp, with a GC content of 66.83%) and major findings from its annotation, which could provide insights into its petroleum biodegradation mechanism.

The relation between occupational factors and pancreatic cancer has been studied by two different approaches: a population based case-control study with two series of controls and a retrospective cohort study based on register data. With both approaches, some support was found for an association with occupational exposure to petroleum products. Associations were also indicated with exposure to ...

One of the major challenges in petroleum industry is producing residual oil from underground. One of the major techniques for enhancing oil recovery (EOR) is using gas injection. However, gas has poor volumetric sweep efficiency, this is attributed to its high mobility which considers to be higher compared with oil and water mobility. Several techniques are proposed and applied for reducing gas...

This paper uses a ßexible approach to characterize the nonlinear relation between oil price changes and GDP growth. The paper reports clear evidence of nonlinearity, consistent with earlier claims in the literature— oil price increases are much more important than oil price decreases, and increases have signiÞcantly less predictive content if they simply correct earlier decreases. An alternativ...
