As a result of the content of benzene in various streams of refinery products, including gasoline, it is not surprising that over the years studies and case reports have linked gasoline exposure to lymphopoietic cancers (LPC), particularly leukemia and multiple myeloma (MM). Of three recently conducted studies of gasoline-exposed workers, one shows strong associations with leukemia and MM, a se...

EPA’s charge from the NEPD included exploring ways to increase the flexibility in the distribution infrastructure, improve fungibility, and provide added gasoline market liquidity. In addition to looking at distribution system impacts, EPA analyzed how the various options could affect the overall supply of gasoline from refineries in the U.S. (i.e., gasoline production capacity). Analyzing the ...

Approximately 11% and 25% of annual Canadian oil spill accidents are gasoline and diesel spills, respectively. Gasoline and diesel spills are a challenge to conventional environmental forensic techniques because refinery processes remove most of the higher molecular weight biomarkers. This study presents a tiered environmental forensics strategy that includes such information as site operationa...

Our objective in this study was to assess the effect of using two kinds of lead-free gasoline [including 92-lead-free gasoline (92-LFG) and 95-lead-free gasoline (95-LFG), rated according to their octane levels] to replace the use of premium leaded gasoline (PLG) on the emissions of polycyclic aromatic hydrocarbons (PAHs) and their corresponding benzo[a]pyrene equivalent (BaP(eq)) amounts from ...

Healthcare rationing means the equitable distribution of limited healthcare resources. The means of distribution and the manner in which these choices are made varies depending on each person's perspective. Rationing already occurs in the United States in areas such as organ transplantation.

Fire and explosion accidents often occur in storage tanks leading to great economic loss and serious casualties during the working, operation and maintenance. This paper established a reduced-scale storage tank experimental system, and then the explosion characteristics of gasoline-air mixture in storage tank were studied. The experimental results show that several parameters (such as concentra...

The phaseout of leaded gasoline would be a significant step forward in the reduction of a major source of exposure; however, this undertaking , even if successful, will have limited public health impact if other sources of exposure are not substantially reduced. For instance, in Mexico City, after the introduction of unleaded gasoline in 1990, lead concentrations in air declined from 1.2 pg/m3 ...

Title of Thesis: IMPLEMENTING AND EVALUATING ALTERNATIVE AIRSPACE RATIONING METHODS Degree candidate: Jason Matthew Burke Degree and year: Master of Science, 2002 Thesis directed by: Professor Michael O. Ball Institute for Systems Research While airport congestion has long been viewed as a major air traffic management problem in the United States, congestion in the en route airspace is drawing ...

BACKGROUND Societal preferences have to be taken into consideration to ensure difficult healthcare decisions are legitimate and acceptable. It has been interesting to ascertain whether attitudes towards the principles of public healthcare resources allocation are homogenous. In particular, it has been thought provoking to ask whether advancement in medical technologies, and growing accessibilit...

A Constitutional Theory of the Family The paper re-examines the idea that a family can be viewed as a community governed by a self-enforcing constitution, and extends existing results in two directions. First, it identifies circumstances in which a constitution is renegotiation-proof. Second, it introduces parental altruism. The behavioural and policy implications are illustrated by showing the...
