The addition of ethanol into gasoline has long been a method to help the hydrocarbons of gasoline burn smoother in an internal combustion engine by adding oxygen into the fuel. Gas stations list ethanol content in gasoline can be up to 10% ethanol but no more than 10% ethanol. By using the methods of standard addition, using known concentrations and volumes of spikes of ethanol into the gasolin...

Since 1970, vehicle’s exhaust pollutions have received increasing attention as a source of air pollution at both local (human health concerns) and global (global warming) scales. This study mainly discusses diesel and gasoline vehicles because, today, over 90% of vehicles on the road use gasoline and diesel fuels. The major concerns of gasoline exhaust contaminants are carbon monoxide (CO), hyd...

Exploiting a rich data set of new vehicle registrations in 22 U.S. Metropolitan Statistical Areas from 1999 to 2006, we analyze the determinants in the demand for hybrid vehicles and examine government programs that aim to promote the adoption of hybrid vehicles. We find that both the recent run-up in gasoline prices from 1999 and federal income tax incentives are important in the diffusion of ...

Ethanol use in vehicle fuel is increasing worldwide, but the potential cancer risk and ozone-related health consequences of a large-scale conversion from gasoline to ethanol have not been examined. Here, a nested global-through-urban air pollution/weather forecast model is combined with high-resolution future emission inventories, population data, and health effects data to examine the effect o...

Increasing numbers of young women are employed as gasoline station attendants in most developing countries despite the lack of empirical data on the adverse reproductive health effect of this solvent. This study therefore sought to assess the effects of gasoline inhalation on the serum sex hormone profile and menstrual characteristics of female gasoline station attendants in Nigeria, given the ...

Imagine a world where government regulation of gasoline, justified by scarcity of supply, allowed 20% of the gasoline in the U.S. to be used for farming; 20% for manufacturing; 20% for home use; 20% for government; and another 20% held in reserve for future potential government uses. In this world, prices would regulate the use of gasoline within each sector, but consumers would pay vastly diff...

Retail gasoline sales generally take place in an incredibly competitive environment with highly visible prices, many competitors, and homogeneous goods. Here, we show how price–cost margins have changed era of drastic changes to transportation choices. We find that increasing COVID-19 case rates increased firms’ market power the retail sector, effectively halving station-level price elasticity ...

Characterization and evaluation of a biological submerged filter was carried out on a full-scale pilot plant performing removal of biochemical oxygen demand (BOD) and total nitrogen (TN) from pre-treated urban wastewater. The average influent values of BOD5, chemical oxygen demand (COD) and TN were 370, 1,015 and 60 mg/L, respectively. The pilot plant produced good discharge quality during stea...

We use naturalistic driving data to analyze the refueling behavior of drivers. The data come from a year-long study in which drivers were provided with experimental vehicles to use for seven weeks. We use data logged during the experiment to identify the time and location of refueling stops. With this dataset, we estimate a discrete choice model for the driver’s choice of refueling location. We...

Abstract Increasing biofuel production over the last decade and policies in Brazil, European Union, United States have changed global agricultural landscape terms of land-use, commodity prices, trade. fuel efficiency electrification vehicle stock is projected to lower gasoline, diesel, demand future. In this analysis, we quantify effects a 30% reduction ethanol consumption U.S. Union triggered ...
