In 2000 the price of crude oil rose to levels not seen for more than 20 years, and as a result so did the price of oil products. The price hikes prompted public debate about the level of taxes determining the final prices paid by consumers. By one estimate, taxes accounted for 68 percent of the final price in the European Union in 2000 (OPEC 2000). But what about developing countries, where pet...

The NAKHODKA and ERIKA oil spills in Japan and France, respectively, have once again focused the attention of politicians, regulators, the media and claimants on the potentially high cost of such events and the adequacy of the current international compensation arrangements. As will be explained by another speaker at the Conference, this has led to a proposal for a Supplementary Fund that would...
This paper examines the effect of anticipated and unanticipated changes in oil prices and gasoline inventory on US gasoline prices. We estimate empirical responses to anticipated and unanticipated changes in oil prices and gasoline inventory and show that gasoline price adjustments are faster and stronger for anticipated changes in oil prices and inventory levels than for unanticipated changes....
Despite their importance as ecosystem drivers, our understanding of the influence of bacterial diversity on ecosystem functioning is limited. After identifying twelve bacterial strains from two petroleum-contaminated sites, we experimentally explored the impact of biodiversity on total density by manipulating the number of strains in culture. Irrespective of the origin of the bacteria relative ...
In methanogenic sediments from a petroleum-contaminated aquifer, [14C]benzene was converted to 14CH4 and 14CO2 without an apparent lag. Phenol, acetate, and propionate were intermediates in benzene mineralization. These results suggest that alternative electron acceptors need not be available for there to be significant natural attenuation of benzene in some petroleum-contaminated aquifers.
...I think [petroleum intermediates] poses one of the great problems before our company today. Should we get into it at all; if so, how deeply? What are our advantages or disadvantages opposite the many others who are already interested in that field among both chemical manufacturers and petroleum anufacturers? -W.S. Carpenter, Jr., Du Pont President, o C.H. Greenewalt, August 16, 1946 [Carpent...
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. OUST has consulted on several occasions with experts in the field of vapor intrusion an...
