Literature Review : Air Pollution Dispersion Modelling

With a declining or no use of cars can result in the reduction of pollution quite tremendously. They can by reducing the greenhouse effect. As the author reports in the article, “In German Suburb Life Goes On Without Care” by Elisabeth Rosenthal, “Passenger cars are responsible for 12 percent of greenhouse gas emissions in Europe… and up to 50 percent in some car-intensive areas in the United States.” Therefore, with cars being a leading factor of greenhouse gas emissions, reducing their usage would have a positive effect on the environment. After days of near-record pollution,

As the exploration of the industrial development and increased speed of the urban sprawl in Beijing, many severe environmental issues attribute mainly to the anthropocentric activities have been come out of the scene. One of them is the air pollution. Air pollution has been regarded as the most severe environment issue in China since it has already threatened to physical health, especially for the respiratory tract and lung. “In January 2013, Beijing experienced historical heavy air pollution. In this particular month, very few days were observed with blue sky.” (Lijian Han et.al., 2015) According to the analysis of the driving factors, “the population grew fast, and energy consumption and the number of vehicles increased rapidly” (Ju Zhang et.al., 2010), these factors add together can make the air quality worse than any one of them separately can. Firstly, it has been an undoubted truth that more and more people originally lived in rural has been moved to core urban of Beijing since there are more opportunities in there. Therefore, the huge explosion of urban population with more energy release and more CO2 exhalation is seen as an inevitably primary factor causing the bad air quality. What’s more, as the population

Introduction Automobile usage has increased in America and elsewhere in the world. In a research done by Sutherland, J., et al. (2004) “The US has a contributed to 200 million passengers in cars and light truck over the past few years. Further in 1990, studies showed that US cars increased six times faster than human population. The leaders in the automotive industry must adopt some key elements to ensure success in this fast-moving environment. They must invest in knowing their markets, building brands, adapting product strategies and taking long-term view on their goals and objectives. This paper outlines some of the key factors which should be considered. Environmental factors automotive designers and engineers have always said the main threats in the American Automotive industry are the environmental factors such as fuel economy and the clean air regulations. Automotive Emission posed different problems than manufacturing discharges such as coal smoke. Increased fossil-fuel emission has resulted from the million car increase. Irritation smog, which is comprised of carbon monoxide, hydrocarbons, sulfur oxide and other various chemical mixtures are cited in major cities such as Los Angeles. These auto emissions are also said to cause headaches, visual pollutions, contribute to lung cancers and other respiratory disease. In the end, the engineers have designed cars that are better environmental performers, cost effective and fuel efficient to reduce the environmental

Pollution has become a heated issue in recent years. The destruction of the environment along with serious health problems are the eventual effects. The extensive use and availability of automobiles, tremendous amounts of production in the booming economy and the constant increase in demand for energy, can be held responsible.

Even if all countries in the world contribute to the air pollution, the developed countries take the leading role on releasing carbon monoxide in the air. This toxic air increases risk of the ozone layer depletion, which potentially would expose UVB radiation at the earth. This UVB radiation has negative consequences on humans, animals, plants and other planetary creatures. In addition to UVB radiation the polluted air by itself can cause serious health problems for humankind. Moreover, this process would cause the earth to become warmer which consequence of global warming. Industries and transportation takes the first place for the source of emissions of air

Due to advancement in technology, there has been an increase in emission of pollutants from the vehicles. Electric cars do not produce pollutants which are very important for the cities to stay green and pollution free as the air quality has deteriorated a lot.

Although thought to be “not a big problem” and “under control” by most people, pollution is making its way in being a serious and an unforgiving threat to society. Pollution a topic everyone hears and knows exists. What they don’t know is how serious of a problem it is already becoming. Many health issues are being reported now that are linked to air pollution and even the most severe weather places have encountered are linked to air pollution also. By society, not fully being aware of the true threat that pollution is making, it will only become a growing threat that they will be encountering.

Over the past decade, particulate matter (PM) is increasing the air pollution at an exceeding

Introduction: Air pollution in modern society is becoming more and more of a pressing issue. I became intrigued when I learned about the level of air quality in places such as Beijing, New York City, and London. I was curious about the air quality in a smaller large scale city such as Savannah, GA. Savannah is a large city but has a smaller population than Atlanta. I also thought about how the air quality could improve after it rains.

The large majority of todays cars and trucks travel by using internal combustion engines that burn fossil fuels and gasoline. A variety of emissions are polluted into the atmosphere when burning gasoline to power cars and trucks. Emissions that are released directly from cars and trucks into the atmosphere are the primary cause of car pollution but it still causes pollution the air during the manufacturing and refueling processes. Primary pollution from motor vehicles is pollution that is emitted directly into the atmosphere where as secondary pollution is caused from chemical reactions between pollutants after they have been released into the air at least 92 million Americans still live in areas with chronic smog problems. The U.S. Environmental Protection Agency predicts that by 2010, even with pollution controls more than 93 million people will live in areas that violate health standards for ozone (urban smog) and more than 55 million Americans will suffer from hazardous levels of fine particle pollution, which is especially dangerous to children and senior citizens.

Beijing, China has a coal mining history of nearly 800 and some odd years. This has been a major air pollutant and the main reason for it is because its economy has grown substantially in the last 30 years. Worldwide, there are twenty cities with the highest, worst air pollution, sixteen of those cities are within China alone. The main causes of Beijing’s air pollution can be pointed to several factors. Large economical growth, an increase in vehicles on the roads, growth in population, and manufacturing. China has also experienced major economic growth with a large rise in Gross Domestic Product. This increase can be connected with pollution. Vehicles are just one contributor to pollution which we will discuss later in this paper.

Akio Toyoda, the founder of the car company Toyota Incorporated, once said “Automobiles are the pinnacle of human transportation. The percentage of families across the world who own cars have reached new heights in the past decade. Multiple families now have an easier form of transportation than walking or taking an overcrowded bus. For that reason, I am happy with what I do.” Akio Toyoda is right for saying so. The usage of automobiles increases by 150% since the past decade as more consumers look towards faster and cheaper methods of transportation. The increase in usage brings many concerns to well-minded citizens, specifically concerns regarding the environment and the conservation of energy. In order to tackle the problem locally, multiple

Air, is one of the most substantial source to mankind and our planet. While it exists, so does everything else along. However, in today’s epidemic, there has been certain factors that have increased in understanding whether the air we breathe today is healthy or not? Is it doing more harm than we thought? In other words, the health risks against air pollution have risen in the past few decades; all from what you may ask? Well, it could be for various factors and evaluations; either environmental or materialistic. Pollution is a major public health crisis in the world. (Friis, 2012). This is one of the conflicts that contribute to various aspects of an individual’s life, whether they may realize it or not. In this paper will include the sources that cause pollution with the effects it cause as well as policies on the regulation of air pollution.

“Automobiles have a large impact on the quality of our environment and public health. Automobile use affects virtually every aspect of environmental quality - including noise levels, air quality, water pollution, and urban sprawl. Ninety percent of the environmental impact of automobiles occurs through the operation of the cars: about 10 percent from the production, raw materials and disposal of

The amount of factories and industries has grown immensely through the previous years which has resulted in an expansion in the consumption of petroleum products. Innovation has begun to increase and has promoted the expansion of the production of cars. As stated by the Air Quality Research Center, “Air pollution is one of the most dangerous environmental problems, causing many adverse health effects and responsible for 50,000 deaths in the U.S. each year” (Air Pollution and Health – Air Quality Research Center.). The smog and
