OBJECTIVE The price of gasoline has been found to be negatively associated with traffic crashes in a limited number of studies. However, most of the studies have focused either on fatal crashes only or on all crashes but measured over a very short time period. In this study, we examine gasoline price effects on all traffic crashes by demographic groups in the state of Alabama from 1999 to 2009....

Our model suggests that spot diesel should rise 25 cents a gallon over the next six months and 41 cents a gallon over the next 18 months. americans who drive cars are no doubt aware of the drastic rise and fall in gasoline prices over the past few years. What they may not have noticed is the unusual movement in the price of diesel, a fuel primarily used in trucks, buses, railroad engines, farm ...

We would like to alert toxicologists to the importance of testing for gasoline, and for volatile hydrocarbons in general, in deaths involving inhalation of exhaust fumes occurring in closed spaces with running motors or machinery. We present here a case of suicidal inhalation of motorbike exhaust, a mixture of carbon monoxide (CO) and gasoline vapor, by a 38-year-old female. She was found in he...

Hydrocarbons (benzene, toluene, ethyl benzene and xylene (BTEX) found in gasoline and organic solvents are ubiquitous in the environment, and are known to have toxic effects in human system. This study therefore investigated the thyroid function of workers occupationally exposed to gasoline and paint products using TSH, T3 and T4 as markers. A total of 162 subjects were recruited for this study...

Introduction: Benzene, Toluene, Ethyl Benzene and Xylene (BTEX) are Volatile Organic Compounds (VOCs) with similar physical and chemical characteristics. BTEX existing in gasoline releases to the air in result of the gasoline evaporation and the staffs are exposure to it in gasoline stations. The main goal of this project is to determine the risk of occupational exposure to BTEX compounds amon...

Six popular approaches of «NIR spectrum–property» calibration model building are compared in this work on the basis of a gasoline spectral data. These approaches are: multiple linear regression (MLR), principal component regression (PCR), linear partial least squares regression (PLS), polynomial partial least squares regression (Poly-PLS), spline partial least squares regression (Spline-PLS) an...

This review examines the animal, human, and mechanistic studies that precede the new studies reported in this volume. Wholly vaporized unleaded gasoline was found to produce a dose-dependent increase in renal carcinoma in male rats and an excess above background incidence of hepatocellular tumors in female mice in the high-dose group. Mechanistic studies suggest that gasoline is not mutagenic a...

This paper uses a unique data set of monthly new vehicle sales by detailed model from 19702007, and implements a new identification strategy to estimate the effect of gasoline prices on new vehicle demand. We control for unobserved vehicle and consumer characteristics by using within model-year changes in gasoline prices and vehicle sales. We find a significant demand response, as nearly half o...

The authors presented the contribution of gasoline vehicle exhaust to SOA formation in urban atmosphere. The manuscript indicated the importance of the vehicular gasoline compositions and clariïňĄed the principal problem of vehicular emissions for haze pollution in China. However, in your literature review, the authors missed some new ïňĄndings. E. g. Tang et al. (2015) illustrated the differen...
