Chemical deicing plays a fundamental role for traffic safety on roads and runways in winter season. Traditional deicing chemicals, such as sodium chloride and urea have, however, undesirable effects on surface and ground waters. For more sustainable road and runway winter maintenance, easily biodegradable organic salts such as acetates and formates, have been proposed and taken into use. Next t...

Petroleum is an indispensable chemical product in industrial production and daily life. The hydrocarbon molecules petroleum are important raw materials the organic industry. hydrocarbons currently used industry usually obtained by fractional distillation of petroleum, which not only consumes more energy, but has poor separation selectivity for some hydrocarbons. Adsorption technology many advan...

BACKGROUND Heightened awareness of the health benefits of fish oil consumption has led to a great increase in the number of fish oil supplements available to the consumer. Therefore manufacturers are continually looking for ways to distinguish their products from those of competitors. Minimally refined or virgin fish oils provide a unique feature; however, petroleum hydrocarbon contamination fr...

Biological markers are organic compounds in geological samples with an unambiguous link to specific precursor molecules in living organisms. They provide information on the origin and depositional environment of fossil organic matter as well as about its thermal maturation caused by geothermal heat flow during burial. Petroleum and its refinery products carry this biomarker information into the...

Ecological disasters resulting from oil spills have created a great need to find more efficient materials for oil spill cleanup. This research highlights the use of a novel macroporous polymeric material based on butyl rubber (BR) as a sorbent in an oil spill cleanup. The sorption capacity of BR for crude oil and petroleum products is 15-23 g g(-1) as compared to the value of 10-16 g g(-1) obta...

LPG (Liquefied Petroleum Gas) is a petroleum derived, colorless gas, typically comprised of mainly propane, butane, or a combination of these two constituents. LPG fuel for vehicles is actually a mixture of various hydrocarbons which are gases at atmospheric pressure and temperature but which liquefy at higher pressures like less than 200 psi. LPG is a natural derivative of both natural gas and...

Natural remediation of oil spills is catalyzed by complex microbial consortia. Here we took a whole-community approach to investigate bacterial incorporation of petroleum hydrocarbons from a simulated oil spill. We utilized the natural difference in carbon isotopic abundance between a salt marsh ecosystem supported by the 13C-enriched C4 grass Spartina alterniflora and 13C-depleted petroleum to...

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...
