This book provides a dynamic simulation model based on input-output table. The model includes an objective function, i.e. maximizing economic and social development and three sub-models, including economic growth model, pollutant emission model and energy balance model. The data of 2012 is selected as the base period data. The haze control policy of Hebei Province is written into the model as an exogenous variable. Reducing the total PM2.5 emissions is an environmental constraint, which is used to eliminate the impact of natural factors on environmental quality. Lingo software is used to simulate this model. By comparing the socio-economic impacts in different scenarios, this book found the most effective policy combination of haze governance. Comprehensive haze governance policy recommendations provide experience for other regions of China and other developing countries. In this book, the dynamic simulation model of haze governance also provides a reference to other environmental policy simulations. This book is divided into five parts. The first part is an introduction. This paper mainly introduces the research background, research status at home and abroad, the purpose and significance of the study, the content and methods of the study, the key scientific problems to be solved and the expected results. In the second part, the current situation and existing problems of economic, social, energy and environment development in the study area are analyzed in detail. In the third part, a comprehensive evaluation model of dynamic optimization of haze control policy is constructed. The fourth part carries on the simulation experiment, and carries on the analysis to the experimental result. The fifth part puts forward the policy suggestions to realize the economic, social, energy and environmental development of Hebei Province. In this book, we have some understandings about haze governance. From the perspective of policy effect, the policy effects of subsidy for soil and water conservation, subsidy for development and utilization of clean energy, subsidy for new energy vehicles, motor vehicle restriction and subsidy for introduction of PM2.5 treatment technology are decreasing. Comprehensive policy can better achieve the goal of sustainable development of economy, energy and environment than single policy, and the effect of "source governance" policy is better than that of "end governance" policy.

It has often been said that generals prepare for the next war by re-fighting the last. The Deepwater Horizon (DWH) oil spill was unlike any previous - an underwater well blowout 1,500 meters deep. Much has been learned in the wake of DWH and these lessons should in turn be applied to both similar oil spill scenarios and those arising from "frontier" explorations by the marine oil industry. The next deep oil well blowout may be at 3,000 meters or even deeper. This volume summarizes regional (Gulf of Mexico) and global megatrends in marine oil exploration and production. Research in a number of key areas including the behavior of oil and gas under extreme pressure, impacts on biological resources of the deep sea, and the fate of oil and gas released in spills is synthesized. A number of deep oil spills are simulated with detailed computer models, and the likely effects of the spills and potential mitigation measures used to combat them are compared. Recommended changes in policies governing marine oil exploration and development are proposed, as well as additional research to close critical and emerging knowledge gaps. This volume synthesizes state-of-the-art research in deep oil spill behavior and response. It is thus relevant for government and industry oil spill responders, policy formulators and implementers, and academics and students desiring an in-depth and balanced overview of key issues and uncertainties surrounding the quest for deep oil and potential impacts on the environment.
Fossil hydrocarbons form a continuous series
whose"heavy"members--heavy oils, bitumens, oil shale kerogens, and
coal--are important sources of conventional lighter fuels. These
hydrocarbons are much more abundant and easier to extract than
natural gas and oil. This book discusses the origins and
compositions of fossil hydrocarbons and shows how the"heavies"can
be chemically transformed into environmentally clean gas, liquid
transportation fuels, and an almost unlimited range of
petrochemicals.

Civilization's negative impact on the environment has vastly accelerated since the onset of the industrial revolution. Serious environmental contamination now threatens many ecosystems and perhaps ultimately the human race. While some of the most visible urban pollution may have abated, the larger problems of regional and global pollution, particularly by an ever-increasing number of trace contaminants, remain far from solved. While the link has been clearly established between long-range transport of gaseous pollutants and environmental issues such as acid rain, the greenhouse effect, and Arctic haze, the scientist's understanding of the fate of these pollutants in the atmosphere has been constrained by the lack of suitable analytical methods, the complexities of pollution sources, and the volume of potential contaminants involved. This volume offers some of the research tools needed to begin untangling these riddles: appropriate measurement technology, sophisticated analytical techniques, and a better understanding of physical and chemical processes in the atmosphere. Chapters by leading environmental scientists from the world over discuss: . Standard and new methods of sampling and analyzing gaseous contaminants in the atmosphere. The uses of these analytical methods in deciphering material fluxes. The sources, occurrences, and characterization of volatile organic compounds in both indoor and outdoor environments. Gaseous Pollutants will be of great interest to scientists and engineers interested in monitoring air quality; atmospheric chemists studying the behavior and fate of trace contaminants in the air; and anyone concerned with air pollution and pollution control strategies. Inaddition to presenting a valuable profile of current research results, this book outlines the challenges that lie ahead, pointing students and environmental professionals alike toward important research opportunities in this dynamic field.

Air pollution challenges nations sharing common borders to balance economic needs with protecting citizens and the environment across jurisdictions. By examining landmark cases on the two borders, John Wirth shows how environmental diplomacy, citizen action at the grassroots level, and the role of science, industry, and the law converged, bringing Canada, the United States, and Mexico to the threshold of today's continental approaches to pollutant pathways. Wirth first examines the famous Trail smelter conflict of 1927-1941. This precedent-setting case, which pitted U.S. farmers against the Canadian smelter, resulted in the doctrine that in cases of transborder damage, the polluter must pay. Although the farmers were modestly compensated and the British Columbia-based smelter cooperated to control pollution, Wirth reveals the real significance of the decision: U.S. industries shared with the Canadians a common interest to resolve the case in a manner that would allow them to continue to pollute freely across international borders with minimal regulation. Wirth then turns to the Gray Triangle confrontations of the 1980s, in which the new instruments of the Clean Air Act and cooperative policies developed by the Mexican and U.S. governments established an entirely new climate for citizen action, resulting in the closing of an American smelter in Arizona and the imposition of stricter standards on two Mexican smelters in Sonora. Although the Trail precedent favored industry, the Gray Triangle resolution signaled that the needs of industry and the public interest were now in better balance. Drawing on extensive interviews and previously untapped archives, Smelter Smoke in North America provides new analysis of the development of a North American institutional response to continental air pollution. It chronicles how industry developed a continental perspective in a shared regional space, the mineralized West, and how successful efforts of governments and citizens to protect the environment evolved.
