Biofiltration of volatile organic compounds of Brazilian gasoline BABT
Rizzolo,Joana Antunez; Santos,Vanessa Cristina de Castro; Soares,Marlene; Woiciechowski,Adenise Lorenci; Soccol,Carlos Ricardo.
Gasoline vapors pollute the atmosphere and can be harmful to human and animal health. Tons of particles of this pollutant are expelled to the atmosphere, generating great economic losses to the industries and serious damage to the environment. Biofiltration is an option of simple technology with low costs that can be used for the gasoline vapor treatment. The present study was carried out in two biofilter systems of laboratorial scale. The biofilter system 1 was operated with a total volume of 2.72 L (four columns) and the biofilter 2 with 2.04 L (three columns) of total volume. Both of them were operated in sequence, with airflow of 450 mL entering each one. Results obtained were as follows for the removal efficiency (RE) of different gasoline vapor...

Gasoline biodegradation in different soil microcosms BJM
Cunha,Cláudia Duarte da; Leite,Selma Gomes Ferreira.
The objective of this study was to evaluate gasoline biodegradation in batch soil microcosms. Microorganisms able to grow in the presence of gasoline were isolated from soil. Several treatment systems were performed using both isolated strains and Pseudomonas putida obtained from a culture collection. The treatment system using only autochthonous microflora (system 1) presented an average value of degradation of 50%. The association of Pseudomonas putida, Burkholderia cepacia, Pseudomonas alcaligenes and the native soil microflora (system 13) presented significant percentage of removal of n-undecane (88.7), n-dodecane (61.3) and n-tridecane (66.7). According to these results, systems 1 and 13 revealed considerable potential for application in...

Impact of fuel costs on high-latitude subsistence activities Ecology and Society

Most rural residents in Arctic communities rely on motorized transportation to hunt, fish, trap, and gather subsistence resources. Although these technologies have created advantages, one significant disadvantage is that peoples’ ability to meet their nutritional and cultural needs now depends on consistent opportunities for wage employment and availability of affordable fuel. Recent qualitative research suggested that rising fuel prices have disrupted subsistence lifestyles in the Arctic. Our objectives were to collaborate with subsistence users in rural Alaskan communities to quantify how rising fuel costs have impacted subsistence activities and explore ways local residents may adapt to the trajectory of change. We conducted interviews with...

Policy-Induced Technology Adoption: Evidence from the U.S. Lead Phasedown AgEcon
Kerr, Suzi; Newell, Richard G..
The theory of environmental regulation suggests that economic instruments, such as taxes and tradable permits, create more effective technology adoption incentives than conventional regulatory standards. We explore this issue for an important industry undergoing technological responses to a dramatic decrease in allowed pollution levels - the petroleum industry's phasedown of lead in gasoline. Using a panel of refineries from 1971 to 1995, we provide some of the first direct evidence that alternative policies affect the pattern of adoption in expected ways. Importantly, we find that the tradable permit system used during the lead phasedown provided incentives for more efficient technology adoption decisions. Where environmentally appropriate, this suggests...

The Market-based Lead Phasedown AgEcon
Newell, Richard G.; Rogers, Kristian.
The U.S. lead phasedown was effective in meeting its environmental objectives, and did so more quickly with the allowance of permit banking. The marketable lead permit system was highly costeffective, saving hundreds of millions of dollars relative to comparable policies not allowing trading or banking. Estimates suggest that transaction costs brought about only a modest reduction in program efficiency. The market-based nature of the program also provided incentives for more efficient adoption of new lead-removing technology, relative to a uniform standard. Distributionally, it is likely that the program was actually more responsive to the cost concerns of small refiners than a similar uniform standard would have been. The flexibility of the program likely...

Like Products, Health and Environmental Exceptions: The Interpretation of PPMs in Recent WTO Trade Dispute Cases AgEcon
Read, Robert.
This article is concerned with the ongoing debate on process and production methods (PPMs) and the extent to which existing GATT 1994 articles and WTO agreements are able to deal with these issues. The article provides an overview of GATT articles III.4 on like products and XX on general exceptions as well as the SPS and TBT agreements. It then summarises four recent GATT/WTO trade dispute cases involving PPM issues: tuna-dolphin; shrimp-turtle; gasoline standards; and asbestos. The WTO panel and appellate body decisions in these cases are analysed with regard to articles III.4 and XX in the context of the evolution of WTO case law with respect to PPMs. Inferences are also drawn concerning the likely implications for a potential trade dispute over GM...

Inside the Black Box: Price Linkage and Transmission Between Energy and Agricultural Markets AgEcon
Du, Xiaodong; McPhail, Lihong Lu.
This study addresses the complex relationship between energy and agricultural markets—represented by corn, ethanol, and gasoline prices—particularly in light of the growth in biofuel production. Contemporaneous price response and transmission of market shocks are investigated in a simultaneous-equation system to disclose fundamental driving forces before and after the development of large-scale ethanol production. We use a dynamic conditional correlation multivariate GARCH model to demonstrate a strengthening relationship among corn, ethanol, and gasoline prices. We identify a structural change point at March 25, 2008 using the test by Bai and Perron (2003). The strengthened market relationship is further illustrated by variance decomposition based on a...

Incidence of Federal and State Gasoline Taxes AgEcon
Chouinard, Hayley H.; Perloff, Jeffrey M..
The federal specific gasoline tax falls equally on consumers and wholesalers; whereas state specific taxes fall almost entirely on consumers. The consumer incidence of state taxes is greater in states that use relatively little gasoline.
