Response issued draft vapor intrusion guidance (EPA, 2002), which specifically states that it is not recommended for Subtitle I underground storage tank (UST) sites. EPA's Office of Underground Storage Tanks (OUST) is thus currently developing guidance to address petroleum vapor intrusion (PVI) at UST sites. In September 2009, OUST assembled experts in the field of vapor intrusion and petroleum...

A soil washing study was performed to evaluate the treatability of New River sand contaminated in the laboratory with a petroleum distillate. Unaltered and base-extracted sands were mixed with petroleum hydrocarbons, equilibrated, and washed with water or a surfactant at two different pH values (7 and 12). The surfactant had no significant effect on contaminant removal efficiencies at neutral p...

Plant material was collected from Western Ghats, India, shade-dried and extracted successively with different polarity solvents of petroleum ether and ethyl acetate. The extracts were tested for their antimicrobial activity against Gram-positive and Gram-negative bacteria and against a fungal species using the disc-diffusion method. The antimicrobial activity of extracts of Pongamia pinnata was...

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...

Reactor and reaction engineering play a vital role in petroleum and chemical processing. The aim of this article is to acquaint the reader with the interaction between reactor design=selection and the characteristics of the chemical reaction of interest. Reactor selection and design are the basis of economical and safe operation. Chemical reactions in petroleum refining include a huge spectrum ...

Fossil fuels are used throughout the United States Antarctic Program. Accidental releases of petroleum hydrocarbons are the leading source of environmental contamination. Since 1999 McMurdo Station has been the site of the most extensive environmental monitoring programme in Antarctica. Nearly 2500 surface soil samples were collected from 1999–2007 to determine the spatial ‘‘footprint’’ of petr...

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...

As part of a broad, multldlsciplinary effort to monitor the impact of petroleum exploration activities on the outer continental shelf areas of the Gulf of Mexico, the local effects of a drilllng rig on the benthic environment have been investigated. Petroleum hydrocarbons in or on seawater can become associated with suspended sediment partlcles I and be transported downward and incorporated int...

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...
