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...

1.1.1. Petroleum fuels It is estimated that between 1.7 and 8.8 million tons of petroleum hydrocarbons are released into the marine environment each year, with a best estimate of 3.2 million tons per year. Although major oil spills, like the Exxon-Valdez spill of 1989 or last summer’s Deepwater Horizon spill in the Gulf of Mexico, garner much media and citizen attention, you may be surprised to...

The Deepwater Horizon (DWH) accident, one of the largest oil spills in U.S. history, contaminated several beaches located along the Gulf of Mexico (GOM) shoreline. The residues from the spill still continue to be deposited on some of these beaches. Methods to track and monitor the fate of these residues require approaches that can differentiate the DWH residues from other types of petroleum res...

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...

Pseudomonas aeruginosa strain PK6, a potential petroleum hydrocarbon-degrading soil bacterium, was isolated from a site contaminated by a petroleum hydrocarbon spill from an automobile service station in Junagadh, Gujarat, India. Here, we provide the 6.04-Mb draft genome sequence of strain PK6, which has genes encoding enzymes for potential and related metabolic pathways of the strain.

Crude oil spilled from the Herbaysprit in Oecember 2007 and contaminated Tae Ann Sound shoreline. A weathered oiled sediment collected at the spill area (Tai Ann beach) from 3 months to 12 months after the spil l. The fingerprinting and data interpretation techniques oil spill characterization and identification studies and environmental investigations discussed indude oil spill identification ...

The extractive nature of the petroleum industry sets it apart from other industries in many respects. The nature of this industryplaces it at some‘what o f a disadvantage to other industries when attempts are made to foster waste minimization practices and programs. However, this is no excuse for the industry to not further vigorously pursue minimizing waste. This paper describes the petroleum ...

Funding injections by British Petroleum this summer are fueling studies in the Gulf Coast, raising hopes that the Deepwater Horizon oil spill might provide answers to long-standing questions on the nature of cellular toxicity. Rebecca Alvania investigates.

Seabirds exposed to even a dime-sized amount of oil can die of hypothermia in cold-water regions, but despite repeated requests by Environment Canada, offshore oil operators are failing when it comes to self-monitoring of small oil spills, says new research. Chronic pollution from many small oil spills may have greater population-level impacts on seabirds than a single large spill, suggest rese...

This investigation was conducted in an area of oil spill along the east coast of Thailand to examine the relations among cytochrome P450 1A activity in liver and PAHs in the bile of the tonguefish and petroleum hydrocarbons in the sediments. PAH sediment concentrations in the reference and oil spill areas were 5.03 +/- 0.42 and 0.21 +/- 0.043 microg(-1) dry weight respectively Cytochrome activi...
