  • There are two main reasons why the chemical process industry should be motivated to reduce energy consumption and CO 2 emissions: rising concerns in companies, the public and scientifi c community about climate change or global warming, and the increasing fraction of energy in manufacturing costs. ‘ Climate change ’ [1] in this context, means a change of climate, which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods....

  • Diesel engines, also known as CI engines, possess a wide field of applications as energy converters because of their higher efficiency. However, diesel engines are a major source of NOX and particulate matter (PM) emissions. Because of its importance, five chapters in this book have been devoted to the formulation and control of these pollutants. The world is currently experiencing an oil crisis. Gaseous fuels like natural gas, pure hydrogen gas, biomass-based and coke-based syngas can be considered as alternative fuels for diesel engines.

  • Air travel is continuing to experience the fastest growth among all modes of transport. Increasing total fuel consumption and the potential impacts of aircraft engine emissions on the global atmosphere have motivated the industry, scientific community, and international governments to seek various emissions reduction options. Despite the efforts to understand and mitigate the impacts of aviation emissions, it still remains uncertain whether proposed emissions reduction options are technologically and financially feasible....

  • Global warming is the rising average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's average surface temperature has increased by about 0.8 °C, with about two thirds of the increase occurring since 1980. Warming of the climate system is unequivocal, and scientists are more than 90% certain that most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and the burning of fossil fuels.

  • The atmosphere may be our most precious resource. Accordingly, the balance between its use and protection is a high priority for our civilization. While many of us would consider air pollution to be an issue that the modern world has resolved to a greater extent, it still appears to have considerable influence on the global environment. In many countries with ambitious economic growth targets the acceptable levels of air pollution have been transgressed. Serious respiratory disease related problems have been identified with both indoor and outdoor pollution throughout the world....

  • Weather radar is a vital instrument for observing the atmosphere to help provide weather forecasts and issue weather warnings to the public. The current Next Generation Weather Radar (NEXRAD) system provides Doppler radar coverage to most regions of the United States (NRC, 1995). This network was designed in the mid 1980s and deployed in the 1990s as part of the National Weather Service (NWS) modernization (NRC, 1999).

  • Environmental pollution has played a critical role in human lives since the early history of the nomadic tribes. During the last millennium, industrial revolution, increased population growth and urbanization have been the major determinants in shaping our environmental quality. Initially primary air pollutants such as sulfur dioxide and particulate matter were of concern. For example, the killer fog of London in 1952 resulted in significant numbers of human fatality leading to major air pollution control measures....

  • Nevertheless, the broad message of this analysis is fairly clear. Air pollution from maquiladoras has serious consequences for human health, including respiratory disease and premature mortality. However, maquiladoras are clearly not the leading cause of air pollution in Paso del Norte. Moreover, most maquiladoras are probably less important sources of dangerous air pollution than at least one notoriously polluting Mexican-owned industry. Finally, we find no evidence to suggest that maquiladora air pollution affects the poor disproportionately.

  • Mercury released through sewage plants and storm sewers often contaminates the sediments of lakes and rivers on a local scale. However, most of the human-generated mercury that enters the aquatic system is deposited through the atmosphere in rain, snow or attached to small dust particles. Mercury also enters lakes directly from natural geologic sources. In lakes that have been created by hydro dams, very high levels of mercury are often found as a result of natural bacterial processes that become greatly accelerated by the flooding of land and decomposition of vegetation.

  • The municipal and industrial activities of the man affects human health, leads to degradation of the environment and even degradation of the objects built by himself or his predecessors. The pollutants are emitted to the atmosphere with off-gases from industry, power stations, residential heating systems and vehicles, some additional emissions come from the natural sources as volcanoes as well. Fossil fuels, which include coal, natural gas, petroleum, shale oil and bitumen are the main source of heat, electrical energy and are the basic duels for the engines of the transport vehicles....
